Background technology
With the fast development of China's economy and society, people are growing to the demand of electric energy, and power system is continuous
Develop to more extensive direction, get in touch with increasingly closer between each regional power grid, electric power quality and power supply reliability are proposed more
High request, the environmental protection and power conservation requirement to electrical equipment is tightened up.
China is geographical vast, and the north and south temperature difference is big, and especially in the winter time, the outdoor temperature of northeast some areas is up to subzero 50 DEG C
Left and right.Under the conditions of this arctic weather, plastics and part rubber material have become brittle, cracking, or even nature occur and open
Obscission is split, let alone carries out electrical line setting and is constructed.Common wiring is laid in the progress construction of this condition just occurs electric wire
Insulation and sheath cracking, conductor is exposed and can not use.This just brings influence to project progress, and the life to the people brings tired
It is difficult.
The content of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art that there is provided cold-resistant macromolecule modified insulated compound
PVC electric wire.
Resist cold macromolecule modified insulated compound PVC electric wire, including：3 groups by core, conductor layer, conductor shield,

Heating wire；It is characterized in that：The core is arranged on innermost layer, and the outside of core is provided with conductor layer, and the outside of conductor layer is provided with
Conductor shield, the outside of conductor shield, which is provided with the outside of insulating barrier, insulating barrier, is sequentially provided with insulation screen, protective layer, 3
Electric wire is arranged in metal sleeve by isosceles triangle in group, stuffed heat insulated packed layer, metallic sheath between electric wire and metal sleeve in 3 groups
The outside of pipe is provided with external insulation layer, and the outside of external insulation layer is provided with oversheath, oversheath provided with some alloy heat generating silks.
Preferably, the conductor layer is made up of some groups of wrapped silver-plated copper bands on the outside of core.
Preferably, the metal sleeve is the bellows of aluminium alloy or copper product.
Preferably, the conductor shield and insulation screen are the copper cash composition by latticed braiding.
Compared with prior art, the beneficial effects of the utility model：
The utility model is by setting alloy heat generating silk oversheath is generated heat, it is to avoid low temperature produces jelly to electric wire internal structure
Wound, damage；By setting the corrugated metal sleeve of aluminium alloy or copper product, can greatly improve electric wire tensile strength and
Bending property；By the conductor layer for setting silver-plated copper band to be made, the resistance of electric wire can be greatly reduced, transmission of electricity consume is reduced；Tool
Have the advantages that tolerance to cold is strong, tensile strength is high, good bending property, transmission of electricity consume it is low.
