Description
Technical field
The present invention relates to a kind of cable for new-energy automobile, belong to electric wire field.
Background technology
China is vast in territory, and aboundresources highway transportation is one of China's important transportation form, with China's economic construction
Continue to develop visitor, shipping throughput rate increasingly to increase, the demand of Automobile two is also increasing.
The highway transportation of China from original fuel vehicle to the transition of New-energy electric vehicle epoch, fuel vehicle using diesel oil and
Gasoline is used as power and new-energy automobile uses electrical actuation power, due to new-energy automobile using electrical actuation power so being accomplished by substantial amounts of
Electric wire, temperature is high during due to narrow space on new-energy automobile, operation, have lubricating oil to ooze out, also require low cigarette, Halogen,
Insulaion resistance performance fire-retardant and high, so requires that one side new-energy automobile should possess above defencive function, new-energy automobile
Operationally this is clearly to be difficult to accomplish, on the other hand we are it has to be considered that cable should have small volume, resistance to height in itself
The performances such as temperature, oil resistant, wear-resisting, low cigarette, Halogen, fire-retardant and high insulaion resistance, i.e. cable small volume, resistance to height under certain condition
The performances such as temperature, oil resistant, wear-resisting, low cigarette, Halogen, fire-retardant and high insulaion resistance are good, and cable can soak 168 in 180 DEG C of mineral oil
Hour, satisfactory mechanical property do not burn simultaneously under naked light, and cable is maintained to normal operation, so far also without one
Plant the property such as the small volume with excellent properties, high temperature resistant, corrosion-resistant, oil resistant, wear-resisting, low cigarette, Halogen, the resistance of fire-retardant and high insulation edge
The special ultrathin insulating cable of new-energy automobile of energy.
The content of the invention
To overcome above-mentioned deficiency, the object of the invention to provide a kind of small volume, high temperature resistant, oil resistant, wear-resisting, low cigarette, Halogen, resistance
The special ultrathin insulating cable of new-energy automobile of the performance such as combustion and insulaion resistance high, to adapt to different working environments, during burning
Nontoxic is a kind of excellent new-energy automobile private cable to human body fanout free region.
The solution of the present invention is as follows：Cable for new-energy automobile, extrudes in the thick cross-linking radiation polyolefin of 0.2 ㎜ outside conductor
Insulating barrier, extrudes the thick cross-linking radiation polyolefin external insulation layers of 0.1 ㎜ outside described cross-linking radiation polyolefin inner insulating layer；
Protuberance is set outside described cross-linking radiation polyolefin external insulation layer.
Further, described conductor is twisted and multiple strand using multiply tin-plating round copper wire stock.
Further, described protuberance is strip or wavy.
Further, the cross-linking radiation polyolefin external insulation layer surface between described protuberance pastes reflective membrane/fluorescent film.
Core interior insulation is thick low cigarette, Halogen, nontoxic, high insulating property the cross-linking radiation polyolefine material of 0.2 ㎜, this
The fusing point of polymeric material is 260 DEG C, 180 DEG C is reached using heat-resisting peak and continuous temperature in use is 150 DEG C；In fire
Smog and poison gas are not produced under environment, with excellent electric property：Dielectric strength reaches 2 times that 35kV/mm is general material,
Specific insulation reaches 4 × 1016It is 100 times or so of general material；Mechanical strength reaches 2 times that 20MPa is general material.
External insulation layer is thick low cigarette, Halogen, nontoxic, wear-resisting, high flame resistance the cross-linking radiation polyolefin material of 0.1 ㎜
Material, the fusing point of this polymeric material is 260 DEG C, 180 DEG C are reached using heat-resisting peak and continuous temperature in use is 150 DEG C；Tool
There is excellent rub resistance and abrasion resistance properties；There is splendid acid and alkali resistance corrosive nature, oil resistant, even if in the elevated situation of temperature
Under still be able to keep stabilization；Smog and poison gas are not produced under fire hazard environment, oxygen index (OI) reaches more than 35, non-ignitable under naked light
Burn；Dielectric strength reaches 19kV/mm, and specific insulation reaches 4.0 × 1014；Mechanical strength reaches 30MPa.
Interior insulation and external insulation are once completed by the way of co-extrusion, i.e., internal layer ensure that cable electrical performance, outer layer
Ensure that the fire resistance of cable.Because the low cigarette of core interior insulation material, Halogen, nontoxic, high insulating property cross-linking radiation
Polyolefine material, dielectric strength reaches 2 times that 35kV/mm is general material, and it is general material that specific insulation reaches 4.0 × 1016
100 times or so of material；Mechanical strength reaches 2 times that 20MPa is general material, with good electrical property and mechanical performance so
Its insulation thickness can be 1/10th of general material, core outer insulating material be high temperature resistant, corrosion-resistant, oil resistant, it is wear-resisting,
Low cigarette, Halogen, the cross-linking radiation polyolefine material of nontoxic high flame resistance, fusing point is high, heat endurance is good, high temperature resistant；With excellent
Good rub resistance and abrasion resistance properties；Low cigarette, Halogen, the fire-retardant fire resistance that so both improve cable, thus subtract significantly
The small external diameter of cable, can use in new-energy automobile high temperature, narrow space.
Cable of the present invention is provided with some protuberances in outer jacket outer surface, in practice, the protuberance first with outside
Contact friction, cable body is just touched after protrusion friction is smooth, and this design can increase the friction life-span of oversheath.This
Reflective membrane/fluorescent film is pasted outside invention oversheath, when overhauling at night, cable can be first found, overhaul efficiency is improved.
