Abstract

This utility model relates to a kind of power cable, is specifically related to a kind of 19 core power cables.Including the cable core that 19 groups of cross sections are equal and the most stranded, cable core is by conductor and is placed in the insulating barrier outside conductor and forms, and the outside of cable core is enclosed with lapping layer, and the outside of lapping layer is enclosed with flame-retardant layer, the outside of flame-retardant layer is enclosed with restrictive coating, and it is uniform that 19 groups of cable cores are positioned at lapping layer.The material of conductor is tin-coated copper, and the material of insulating barrier is silicone rubber, and lapping layer is copper strips, and the material of flame-retardant layer is chlorosulfonated polyethylene, and the material of restrictive coating is low-smoke non-halogen flame-retardant cross-linking radiation polyolefin.This utility model 19 core power cable, designed by above-mentioned Rational structure and the material type selecting of reasonable science, under the effect of lapping layer, flame-retardant layer and restrictive coating, the mechanically supported performance of this power cable, fire resistance, compressive property, acid-alkali-corrosive-resisting, crack resistence, high pressure resistant, anti-external disturbance etc. can be made to be promoted the most by a relatively large margin.

Description

A kind of 19 core power cables

Technical field

This utility model relates to a kind of power cable, is specifically related to a kind of 19 core power cables.

Background technology

Power cable of the prior art, how in three cores, the structure such as six cores or seven cores, the power cable of this kind of structure is universal There is structural behaviour poor, the defects such as flammability is high.

Utility model content

For technical problem present in prior art, this utility model provides 19 cores of a kind of reasonable in design Power cable.

To achieve these goals, the technical scheme of employing is as follows:

A kind of 19 core power cables, it is characterised in that: include the cable core that 19 groups of cross sections are equal and the most stranded, described Cable core is by conductor and is placed in the insulating barrier outside conductor and forms, and the outside of described cable core is enclosed with lapping layer, described lapping layer Outside is enclosed with flame-retardant layer, and the outside of described flame-retardant layer is enclosed with restrictive coating.

Further, to be positioned at lapping layer uniform for 19 groups of cable cores.

Further, the material of described conductor is tin-coated copper, and the material of described insulating barrier is silicone rubber, and described lapping layer is Copper strips, the material of described flame-retardant layer is chlorosulfonated polyethylene, and the material of described restrictive coating is that low-smoke non-halogen flame-retardant cross-linking radiation gathers Alkene.

This utility model 19 core power cable, is designed by above-mentioned Rational structure and the material type selecting of reasonable science, Under the effect of lapping layer, flame-retardant layer and restrictive coating, the mechanically supported performance of this power cable, fire resistance, resistance to compression can be made Performance, acid-alkali-corrosive-resisting, crack resistence, high pressure resistant, anti-external disturbance etc. are promoted the most by a relatively large margin.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is further described for the ease of it will be appreciated by those skilled in the art that.

As a kind of preferred embodiment of the present utility model, referring to Fig. 1, a kind of 19 core power cables, including 19 Equal and the most stranded cable core 6 in group cross section, described cable core 6 is by conductor 1 and is placed in the insulating barrier 2 outside conductor 1 and forms, described The outside of cable core 6 is enclosed with lapping layer 3, and the outside of described lapping layer 3 is enclosed with flame-retardant layer 4, the outside parcel of described flame-retardant layer 4 Having a restrictive coating 5, it is uniform that 19 groups of cable cores 6 are positioned at lapping layer 3.

The material of described conductor 1 is oxygen-free copper, aluminium alloy or tin-coated copper, and the material of described insulating barrier 2 is polyethylene, silicon rubber Glue, crosslinked polyethylene or F 46 resin, described lapping layer 3 is copper strips, proof copper-wire braided net or tinned copper wire mesh grid, described resistance The material of combustion layer 4 is halogen-free anti-flaming polyolefin, flame-retardant polyurethane thermoplastic elastomer (TPE) or chlorosulfonated polyethylene, described restrictive coating The material of 5 is low-smoke non-halogen flame-retardant cross-linking radiation polyolefin.

Above content is only to structure example of the present utility model and explanation, the technology of affiliated the art Described specific embodiment is made various amendment or supplements or use similar mode to substitute by personnel, without departing from The structure of utility model or surmount scope defined in the claims, all should belong to protection domain of the present utility model.
