Abstract

The utility model discloses a high pressure shielded cable, which comprises a cable body, the cable body includes a plurality of cable cores, outer semi -conductive layer, internal shield layer, external shielding layer and sheath, be equipped with the combination conductor in the cable core, it has covered inner semiconductor layer, the insulating cover of shielding and insulating inner core in proper order to constitute the conductor, the cable core separates through the median, the filling layer has between cable core, median and the outer semi -conductive layer, fill up the filler in the filling layer, the filler is compriseing polypropylene resin, the outer semiconductor electricity layer outside covers there is the internal shield layer, the internal shield layer outside covers there is the external shielding layer. This high pressure shielded cable, the interference killing feature is strong, through the multilayer shield layer, can to a great extent the shielding of reinforcing cable, through the intraformational filler of packing between cable core, median and the outer semi -conductive layer, can increase the compressive resistance of cable, use that can be safer.

Description

A kind of high-tension shielding cable

Technical field

The utility model relates to high-tension cable technical field, is specially a kind of high-tension shielding cable.

Background technology

Cable is normally by the cable of several or the stranded similar rope of several groups of wires [often organizing at least two], and often organize mutually insulated between wire, and be often twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Multi rack is located at aerial or is contained in underground, the bottom, for telecommunication or electric power conveying.1832, tsarist Russia's army officers was permitted woods lattice and telegraphy line is embedded in underground, between six conductors each other with after rubber-covered with being placed in glass tube, a Here it is underground cable the earliest in the world.The insulated conductor that sealing sheath forms is placed in by the conducting wire center of one or more mutually insulated.Protection cover layer can be added outside it, for transmission, distribute electric energy or transmit the signal of telecommunication.Mainly cable dimension is comparatively large for the difference of it and common wiring, and structure is more complicated.

As the service cable of electric energy transmitting, what not only add cable accordingly easily corrodes cable from escheat, and affect cable dissipate heat, finally can only reduce the ampacity of cable conductor and the useful life of cable, for these reasons, obtain and reach designing requirement a kind of useful life, the high performance cable of what properties was excellent the be suitable for basic routing line of electric energy transmitting is brought into schedule.

Utility model content

The purpose of this utility model is to provide a kind of high-tension shielding cable, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme: a kind of high-tension shielding cable, comprise cable body, described cable body comprises multiple cable core, outer semiconducting layer, internal shield, outer shielding layer and sheath, combined conductor is provided with in described cable core, described combined conductor is coated with inner semiconductor layer successively, shielding insulation cover and insulation inner core, described cable core is separated by isolation strip, described cable core, between isolation strip and outer semiconducting layer, there is packed layer, filler is filled up in described packed layer, described filler is for be made up of acrylic resin, described outer semiconductor electric layer outer side covers has internal shield, described internal shield outer side covers has outer shielding layer.

Preferably, multiple auxiliary core and wire core is provided with between described outer shielding layer and sheath.

Preferably, scribble protection cover layer outside described sheath, described protection cover layer adopts the rubber with fire-retardant effect to make.

Compared with prior art, the beneficial effects of the utility model are: this high-tension shielding cable, antijamming capability is strong, by multilayer screen layer, the shielding of cable can be strengthened to a great extent, pass through cable core, filler between isolation strip and outer semiconducting layer in packed layer, the compressive resistance of cable can be increased, use that can be safer, pass through auxiliary core, when staff needs, can use as supervision core, be conducive to the fail safe of monitoring cable core, by protection cover layer, effectively can prevent the cable bad caused because of fire and floods.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

In figure: semi-conductive layer, 13 shielding insulation covers, 14 inner insulating layer, 15 packed layers in 1 cable body, 2 auxiliary cores, 3 protection cover layers, 4 sheaths, 5 outer shielding layers, 6 wire core, 7 internal shields, 8 outer semiconducting layers, 9 cable cores, 10 isolation strip, 11 combined conductors, 12.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of high-tension shielding cable, comprise cable body 1, described cable body 1 comprises multiple cable core 9, outer semiconducting layer 8, internal shield 7, outer shielding layer 5 and sheath 4, combined conductor 11 is provided with in described cable core 9, described combined conductor 11 is coated with inner semiconductor layer 12 successively, shielding insulation cover 13 and insulation inner core 14, described cable core 9 is separated by isolation strip 10, described cable core 9, there is between isolation strip 10 and outer semiconducting layer 8 packed layer 15, filler is filled up in described packed layer 15, described filler is for be made up of acrylic resin, by cable core 9, filler between isolation strip 10 and outer semiconducting layer 8 in packed layer 15, the compressive resistance of cable can be increased, use that can be safer, described outer semiconductor electric layer 8 outer side covers has internal shield 7, described internal shield 7 outer side covers has outer shielding layer 5, be provided with between described outer shielding layer 5 and sheath 4 to scribble outside sheath 4 described in multiple auxiliary core 2 and wire core 6 and protect cover layer 3, by auxiliary core 2, when staff needs, can use as supervision core, be conducive to the fail safe of monitoring cable core, described protection cover layer 3 adopts the rubber with fire-retardant effect to make, effectively can prevent the cable bad caused because of fire and floods.

The utility model improves and is: this high-tension shielding cable; antijamming capability is strong; by multilayer screen layer; the shielding of cable can be strengthened to a great extent; by cable core 9, filler between isolation strip 10 and outer semiconducting layer 8 in packed layer 15; the compressive resistance of cable can be increased; use that can be safer; by auxiliary core 2; when staff needs, can use as supervision core, be conducive to the fail safe of monitoring cable core; by protection cover layer 3, the cable bad caused because of fire and floods effectively can be prevented.
