Abstract
The utility model discloses a halogen-free low-smoke flame-retardant shielded intrinsic type computer cable which comprises a plurality of wire cores, wherein each wire core is formed by twisting two groups of copper conductors (1) coated with insulating layers (2). The halogen-free low-smoke flame-retardant shielded intrinsic type computer cable is characterized in that each wire core is sequentially coated with an internal composite copper aluminum plastic tape (3) and a copper wire braiding pair shield (4) to form a shielded wire pair, a plurality of shielded wire pairs are twisted to form a cable core, filling layers (5) are arranged at clearances of the shielded wire pairs, and an external composite aluminum-plastic tape (6), a total copper wire braiding shield (7), an internal sheath (8), a steel tape armoring layer (9) and an external sheath (10) are coated outside the cable core in sequence. The cable has low capacitance and low inductance, and the charge carried by the cable is less so as not to easily produce electric sparks. In addition, the cable is high in tensile strength and breaking elongation and good in impact strength; and the halogen-free low-smoke cable sheath is prevented from cracking.
Description
Technical field
The utility model relates to a kind of cable, and particularly LSOH anti-flaming shield type computer cable, belong to technical field of electric wires and cables.
Background technology
along with science and technology is constantly progressive, computer is widely used in communication, electronics, oil, chemical industry, weaving, the various type of productions such as colliery, the service type field, computer is in running, cable is required to be it stable electric current is provided, voltage, this just requires its cable must have good anti-electromagnetic interference performance, in addition for ensure calculate function run into adverse circumstances still can safe and stable operation, the low electric capacity of cable, low inductance, anti-flammability, toughness, tensile strength, impact strength is also its indispensable premium properties, as the good cable of computer, how to accomplish both possessed anti-electromagnetic interference performance, possesses again low electric capacity, low inductance, high flame retardant, high tenacity, high resistance is opened, impact strength is the utility model technical issues that need to address.
The utility model content
The problem that exists in order to solve prior art, the utility model provides a kind of LSOH anti-flaming shielding intrinsically safe computer cable, and the power supply environment of a safety and stability is provided for computer.
The utility model technical solution problem adopts following scheme:
LSOH anti-flaming shielding intrinsically safe computer cable, include several cores, every core consists of by two groups of copper conductors that are coated with insulating barrier are stranded, its design feature is, described every core is coated with the line pair that interior aluminium-plastic tape and proof copper-wire braided separated-shielding consist of the composite shielding structure outward successively, the stranded rear formation cable core of a plurality of shielded pairs, the gap of shielded pair is provided with packed layer, cable core is coated with outer aluminium-plastic tape outward successively, proof copper-wire braided always shields, inner sheath, steel-tape armouring layer and oversheath.
The utility model design feature also is:
Described inner sheath and oversheath adopt thermoplastic halogen-free and low-smoke polyolefin elastic material.
Packed layer adopts fire-retardant glass cord.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model cable is provided with separated-shielding and the total shielding pattern that aluminium-plastic tape adds the proof copper-wire braided composite construction, and cable always shields the outside the steel-tape armouring layer, and shielding and steel-tape armouring layer are isolated mutually, this cable has low electric capacity and low inductance, cable itself with electric charge few, be difficult for to produce electric spark.
Oversheath adopts thermoplastic halogen-free and low-smoke polyolefin elastomer material in the utility model cable, and the toughness that it has existing excellence has again good processability, and tensile strength and elongation at break all very high, have good impact strength.Can effectively prevent the oversheath cracking.
3, the utility model cable can not produce pernicious gas and a large amount of smog when burning, has Halogen, low cigarette and fire resistance, does not exist and can cause " secondary disaster ".
Description of drawings
Fig. 1 is the utility model construction of cable schematic diagram.
Number in the figure: 1 copper conductor, 2 insulating barriers, 3 interior aluminium-plastic tapes, 4 proof copper-wire braided sub-shields, 5, packed layer, 6 outer aluminium-plastic tapes, the 7 total screens of proof copper-wire braided, 8 inner sheaths, 9 steel-tape armouring layers, 10 oversheaths.
Technical solutions of the utility model are described further by embodiment below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1, the utility model cable is comprised of copper conductor 1, insulating barrier 2, interior aluminium-plastic tape 3, proof copper-wire braided sub-shield 4, packed layer 5, outer aluminium-plastic tape 6, the total screen 7 of proof copper-wire braided, inner sheath 8, steel-tape armouring layer 9, oversheath 10.
In concrete enforcement, crosslinked polyetylene insulated layer 2 is extruded on copper conductor 1, and two thoroughly do away with the edge core twists together, and then wrapped interior aluminium-plastic tape 3, be provided with proof copper-wire braided sub-shield 4 on interior aluminium-plastic tape; Many shielded pair is twisted together the formation cable core, between shielded pair, the packed layer 5 use low smoke, zero halogen glass cords in space are filled and wrapped outer aluminium-plastic tape 6, be provided with outside the total screen 7 of proof copper-wire braided on aluminium-plastic tape, then be disposed with thermoplastic halogen-free and low-smoke polyolefin elastomer material inner sheath 8, steel-tape armouring layer 9; Thermoplastic halogen-free and low-smoke polyolefin elastomer material oversheath 10.Wherein the count of proof copper-wire braided sub-shield and the total screen of proof copper-wire braided is greater than 85%.The utility model cable has low electric capacity and low inductance, cable itself with electric charge to lack, be difficult for to produce electric spark.Have good anti-external electromagnetic field and disturb and do not produce external interference.Cable tensile strength and elongation at break are all very high simultaneously, have good impact strength.Avoid low smoke, zero halogen cable cover(ing) cracking.
