Definitions
- the invention relates to a data cable.
- a data cable is used for the transmission of signals or data and usually comprises a number of wires, which are combined for example to couple or star quads. Examples of data cables are so-called
- Category 5, 6 or 7 Ethernet cables whose transmission characteristics are usually standardized and specified, for example, in the IEC 61 1 56-5 or IEC 61 156-6 standards.
- the functionality of a data cable is essentially determined by a number of telecommunications transmission parameters, such as impedance, attenuation and return loss of a respective wire.
- the individual wires of the data cable typically each have a conductor and a wire insulation surrounding the conductor.
- the wire insulation is often made of a suitable dielectric plastic to ensure the required transmission characteristics and to realize suitable transmission parameters, for example, to provide a suitable impedance of a respective wire.
- a commonly chosen plastic is polyethylene, for example.
- the data cable has a number of wires, which are designed in particular for the transmission of data or signals.
- a plurality of cores are in each case combined as a core network to form a data line, for example as wire pairs or as quadrilateral composite, in particular so-called star quads.
- the wires each have a conductor which is surrounded by a wire insulation, by which the corresponding wire is formed with a number of predetermined telecommunications transmission parameters, in short only transmission parameters.
- a respective data line is formed with corresponding telecommunications transmission parameters.
- Such telecommunications transmission parameters are, for example, an impedance, an attenuation or a return loss.
- the core insulation is made, in particular, from a plastic which serves as a dielectric, which surrounds the conductor and thereby defines the transmission properties of the wires and, in particular, of the data lines.
- the core insulation has a number of flame retardant layers with a mineral, electrically insulating and flame-resistant first material.
- function preservation means, in particular, that the transmission parameters of a respective core and thus the telecommunications transmission properties the data cable substantially and in particular meet the relevant for the data cable standard.
- a core idea of the invention is, in particular, that the core insulation is made particularly flame-resistant due to the flameproofing layers and thus the data cable can continue to be used as such in case of fire.
- An advantage of the flame retardant layers is, in particular, that even the basic structure of the wire insulation in case of fire remains largely intact.
- a melting of the core insulation is prevented in case of fire, which advantageously preserves the impedance of the wires and thus also the overall functionality of the data cable.
- mineral material is understood in particular to mean a material which is not organic and in particular is not plastic.
- the fact that the first material is also electrically insulating, moreover, a sufficient electrical separation of the conductors of the wires is realized with each other.
- the data cable at least over a certain period of time even in case of fire still continue to be used for data transmission.
- the specially trained wire insulation is thus a functional integrity in case of fire guaranteed.
- Such a trained data cable is particularly suitable, for example, for use in shipbuilding, in the offshore industry, in refineries, tunnels or public buildings.
- An essential aspect of the invention is, in particular, that the mineral material not only in the event of fire, the functionality of fusible components of the data cable, in particular the wire insulation, takes over, but already defined in normal operation, the transmission properties significantly. Since the mineral material is particularly resistant to flame, a particularly good preservation of the transmission properties is guaranteed in case of fire, since the majority or even entire part of the core insulation is maintained in case of fire, and in principle in a same or at least predominantly similar configuration as in normal operation. Function preservation is particularly important with data cables. It is fundamentally to distinguish between the terms function preservation and isolation preservation. For an insulation preservation it is decisive that the insulation, in particular the core insulation, is retained as such and a short circuit is avoided.
- Data cables generally serve digital data transmission at frequencies in the megahertz range, e.g.
- a Category 5E (Cat 5E) cable has a maximum transmission frequency of 250 MHz
- a Category 7 (Cat 7) cable up to 600 MHz.
- conventional messaging cables have comparatively low maximum transmission frequencies in the kilohertz range, e.g. up to 100 kHz, and transmission is usually analog and not digital as with data cables.
- Cables for energy transmission e.g. in the field of power engineering, are operated at much lower frequencies or even with DC voltage.
- transmission characteristics are less dependent on wire insulation, deformation in case of fire is less critical to functionality than data cables. Accordingly, isolation integrity and functional integrity of messaging cables coincide but not with data cables. Higher requirements apply to these.
- Typical requirements for data cables are, for example, no short circuit for voltages up to 100 VDC or up to 70 VAC, in the range between 1 and 10 MHz a maximum difference of attenuation of 8.5 dB, a return loss greater than 8 dB and for frequencies f between 1 and 10 MHz crosstalk greater 26-15 log-i 0 (f / 10) dB. Compliance with the given values is decisive for the functionality of the data cable.
- the core insulation is formed as a mixed dielectric and has, in addition to the flame retardant layers on at least one insulating layer of an electrically insulating second material.
- the additional insulating layer also allows extended protection of the conductor, especially in regular operation, that is not in case of fire.
- the insulating layer is formed continuously in a preferred embodiment.
- the conductor of a respective wire is advantageously completely surrounded by the insulating layer and thus completely protected against environmental influences, for example, penetration of moisture, and on the other hand against accidental short circuit, for example, by contact with other conductors of the data cable.
- the insulating layer is wrapped around the conductor as a foil or banding, laid or folded and welded or glued.
- the insulating layer is made of a plastic, whereby their application, in particular extrusion, is particularly easy on the conductor.
- the insulating layer is therefore extruded, ie formed by means of an extrusion process.
- the insulating layer is made of polyethylene, short PE, polypropylene, short PP or a copolymer manufactured. In addition to advantageous processing properties, these plastics also have a suitable insulating effect.
- the insulating layer is admixed with a flame-retardant or flame-resistant material, for example a mineral additive.
- a flame-retardant or flame-resistant material for example a mineral additive.
- the insulating layer melts or burns and thereby adversely changes the transmission parameters of the respective wire and / or data line, as a result of which the function of the data cable may no longer be guaranteed.
- the insulating layer preferably has a Isolierwanddicke corresponding to a maximum 35%, in particular at most 10% of a total wall thickness of the core insulation.
- the core insulation In the event of a fire, in spite of a melting or burning off of the insulating layer, the core insulation remains structurally intact for the most part, so that the transmission parameters set correspondingly remain largely intact and preferably still lie within the value range specified by the relevant standard.
- the contribution of the insulating layer to the transmission parameters of the core is set such that deformation of the insulating layer only has a small effect on the transmission parameters of the core and in particular of the respective data line. which the vein belongs to, has.
- the insulating layer therefore makes only a small contribution to the impedance, whereby a functional integrity within the tolerance of the impedance is realized.
- the total wall thickness is about 400 ⁇ and then the Isolierwanddicke corresponding to at most about 100 ⁇ .
- the above applies mutatis mutandis to all communication technology transmission parameters of the data cable.
- a key idea here is to make the insulating layer as thin as possible in comparison to the mineral material, so that even in normal operation, the transmission properties are mainly determined by the mineral material.
- a melting of the insulating layer in case of fire then advantageously has little or no influence on the transmission properties, the transmission parameters change at most insignificantly, at least the values described above for the transmission parameters are maintained.
- the preferred Isolierwanddicke is particularly dependent on the arrangement of the insulating layer relative to the flame retardant layers.
- the Isolierwanddicke preferably corresponds to at most 1 0% of the total wall thickness.
- an insulating wall thickness of not more than 25% of the total wall thickness is also suitable.
- an insulating wall thickness of not more than 35% of the total wall thickness is suitable. This difference is due in particular to the generally different contribution to the transmission parameters as a function of the distance of the insulation Layer to the ladder. Accordingly, an insulator layer arranged further in particular has a greater influence and is therefore preferably thinner than a further outermost insulating layer.
- the insulating layer is therefore preferably applied directly to the conductor, in particular extruded and is thus arranged in particular within the flame retardant layers.
- the insulating layer is particularly homogeneous and thus the transmission parameters and accordingly the transmission properties along the vein are particularly homogeneous. Possible bumps are advantageously avoided. In principle, however, an arrangement in the insulating layer around the flameproofing layers or between several flameproofing layers is conceivable.
- the core insulation is exclusively from the
- Flame protection layers constructed and in particular has no additional insulating layer. In this embodiment, therefore, is dispensed with possibly in the event of fire melting insulating layer, so that the transmission parameters of the wire insulation in case of fire due to the flame-resistant flame retardant layers is particularly well preserved.
- the transmission parameters of a respective wire or data line are usually specified by a corresponding standard for the data cable.
- the impedance of a data line which is designed as a wire pair, amount to 100 ⁇ .
- the actual impedance of a particular data line is particularly dependent on the material and the total wall thickness of the wire insulation.
- their core insulation preferably has several flameproof layers. By appropriate selection of the exact number of flame retardant layers, optionally in combination with an additional insulating layer, then the total wall thickness of the core insulation is set such that the predetermined impedance is achieved.
- the flame resistance and electrical insulation are particularly suitable as a first material of a particular flame retardant mineral fission products such as mica or glass fiber.
- These mineral materials are characterized by a particularly good flame resistance and also do not usually melt in the event of fire.
- the shape of the core insulation in case of fire also remains largely preserved, that is, the overall strength of the core insulation and therefore also their transmission parameters remain particularly well preserved.
- the flameproof layers are preferably each formed as a wrap.
- the flame retardant layers are each formed as a banding or braid.
- the aforementioned materials that is mica and glass fiber, but in general any mineral materials can be used in a particularly simple manner to form a core insulation.
- glass silk is braided around the conductor as a braid, knitted or spun.
- Mica is applied as a thin layer on a carrier foil, which is then banded around the conductor or spun or beaten with longitudinal seam around the conductor.
- this embodiment is preferably combined with an additional insulating layer as described above. In this combination is then ensured by the insulating layer continuous coverage and, so to speak, physical shielding of the conductor from the environment and other conductors, the flame resistance and functional integrity are realized by the flame retardant layers.
- the respective core insulation are designed to be as homogeneous as possible, ie with a uniform overall wall thickness.
- the flame retardant layer as a band around the conductor in particular helically wrapped and usually has a plurality of coils which overlap in the edge region of the tape and thus form an overlap, within which correspondingly more material is arranged.
- a respective flame retardant layer is therefore formed with an overlap of at most 20%, in particular at most 10%, and preferably on impact, ie without overlapping. This results in particularly defined and sufficiently uniform transmission parameters of the respective wire along the data cable.
- the overlap is about 49%.
- a respective flame retardant layer is designed by the 49% overlap, in particular quasi double-walled, since in this case a respective coil of the wrapping is each covered about half of the previous and the subsequent coil.
- the formation of an exposed gap is then avoided.
- the previous and the following helix are wound approximately on impact due to the overlap of about 49%, the remaining gap is covered by the intermediate helix.
- about 49% is meant an overlap which forms such a double-layered winding on impact, in particular an overlap of at least 47% and at most 50% is understood.
- the impedance of a data cable according to IEC 61 156-5 or IEC 61 156-6 for functional maintenance in case of fire changes by not more than 20%, in particular not more than 10%.
- the usual tolerance of the relevant standards are then maintained even in case of fire.
- the core insulation is designed with an insulating layer such that the impedance is still within the tolerance, e.g. with 1 10 ⁇ then 10% above an ideal value of 100 ⁇ . If the insulation layer melts or burns in the event of a fire, the impedance is reduced by a maximum of 20% to a corresponding 90 ⁇ and then remains within the tolerated value range, so that standardized data transmission is still guaranteed.
- the functional integrity is maintained in particular over a certain minimum period.
- the transmission parameters and thereby advantageously the transmission properties in case of fire remain over a period of at least 30 minutes, in particular at least 90 minutes and preferably at least 180 minutes.
- the embodiments for the wires and data lines described above already ensure a particularly good flame retardancy and functional integrity in case of fire.
- the data cable in an advantageous development, a cable sheath which surrounds the data lines and their cores and which has a layer which is made of a flame-resistant material. In addition to the flame-resistant flame retardant layers of the individual core insulations, these are therefore surrounded by an additional layer of flame-resistant material. This further improves the flame resistance of the entire data cable.
- a plastic with a corresponding admixture is suitable as the flame-resistant material. meadow a halogen-free polyethylene material. This plastic is then extruded example, and thus forms a particular continuous flame-resistant sheath for the data lines and generally the wires.
- a flame-resistant film is wrapped around the data lines and generally around the wires.
- the data cable has a cable shield, which surrounds the cores, in particular all the cores and, in particular, is designed to electrically shield the cores, in particular the data lines, against the environment and vice versa.
- the cable shield is integrated in particular in the cable sheath, for example, as a braid or wrapping, for example, made of tinned copper wires.
- the data cable has a reinforcement, which in particular surrounds the data lines and in general the wires and in particular serves for mechanical stabilization.
- the reinforcement is designed as a steel braid and integrated into the cable sheath. Conveniently, the reinforcement also serves as additional heat protection.
- the cable has a plurality of wires, which in particular are twisted in pairs and are combined to form a number of data lines. These data lines are surrounded by a common cable sheath. Additionally or alternatively, the data lines are expediently twisted together.
- the data lines each have a cable shield, that is, each of the wires belonging to a data line are jointly surrounded by a cable shield.
- This cable shield is used in particular to shield the various data lines from each other.
- FIG. 4 shows a conductor with insulating layer and flame retardant layer in a side view.
- FIGS. 1 to 3 an embodiment of a data cable 2 is shown in each case.
- This has a number of wires 4, which are combined in pairs in the embodiments shown here in pairs to data lines 6.
- the data lines 6 are each surrounded by a cable shield 7, for shielding against each other.
- a total of eight wires 4 are organized in four data lines 6.
- the data lines 6 are grouped around a central element 8, which is designed in particular as a strain relief.
- the data cable 2 also has a cable sheath 10 which surrounds the cores 4.
- the wires 4 each have a conductor 12, which is surrounded by a wire insulation 14.
- FIGS. 1 to 3 each show exemplary embodiments with different variants of this wire insulation 14.
- the wire insulation 14 in FIG. 1 has a number of, in particular, six flame retardant layers 1 6, which are banded around the conductor 12, for example as a mica foil, or alternatively as a glass fiber wrapped around the conductor 12.
- FIG. 2 shows an exemplary embodiment in which only three flameproof layers are applied to the conductor and are finally surrounded by an additional insulating layer 18.
- This is made of a plastic, such as a polyethylene, and designed consistently, in particular extruded.
- the core insulation 14 is designed in such a way that initially an insulating layer 18 is applied directly to the conductor 12.
- This insulated conductor 12 is surrounded by a number of, here three flame protection layers 14, in particular disgusted.
- the insulating layer 18 is disposed between two flame retardant layers 14.
- the cable sheath 10 in Figures 1 to 3 is designed in multiple layers. On the inside of the cable sheath 10, first a cable shield 19 and a flame-resistant foil 20 are arranged, which surround the data lines 6. Furthermore, a reinforcement 22 is integrated in the cable sheath 10, which is here in particular a steel braid. To further improve the flame resistance of the data cable 2, the cable jacket 10 is admixed with a flame-resistant material, whereby a flame-resistant layer 24 is formed, which also forms an outermost layer of the cable jacket 10 here.
- additional layers or banding are preferably additionally or alternatively arranged, which are arranged inside and / or outside with respect to the cable shield 19.
