Technical field
A kind of cable for new-energy automobile is the utility model is related to, 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 economic construction of China
Continue to develop objective, shipping throughput rate increasingly to increase, the demand of Automobile two is also increasing.
The highway transportation in 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, because new-energy automobile uses electrical actuation power so just needing 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,
Fire-retardant and high insulaion resistance performance, so requires one side new-energy automobile to possess above defencive function, new-energy automobile
It is difficult what is accomplished that operationally this, which is clearly, and on the other hand we are it has to be considered that cable should have small volume, resistance to height in itself
The performance 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 performance such as temperature, oil resistant, wear-resisting, low cigarette, Halogen, fire-retardant and high insulaion resistance is 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
Kind with the property such as the small volumes of 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.
Utility model content
To overcome above-mentioned deficiency, the utility model purpose provides a kind of small volume, high temperature resistant, oil resistant, wear-resisting, low cigarette, nothing
The special ultrathin insulating cable of new-energy automobile of the performances such as halogen, fire-retardant and high insulaion resistance, to adapt to different working environments, combustion
Nontoxic during burning is a kind of excellent new-energy automobile private cable to human body fanout free region.
Scheme of the present utility model is as follows：Cable for new-energy automobile, conductor extrude the thick cross-linking radiation polyenes of 0.2 ㎜ outside
Hydrocarbon inner insulating layer, described cross-linking radiation polyolefin inner insulating layer extrude the thick cross-linking radiation polyolefin external insulation layers of 0.1 ㎜ outside；
Protuberance is set outside described cross-linking radiation polyolefin external insulation layer.
Further, described conductor is twisted using multiply tin-plating round copper wire stock and twisted again.
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 the low cigarette, Halogen, nontoxic, high insulating property cross-linking radiation polyolefine material of 0.2 ㎜ thickness, this
It is 150 DEG C that the fusing point of polymeric material, which is 260 DEG C, 180 DEG C are reached using heat-resisting peak and temperature is used continuously,；In fire
Smog and poison gas are not produced under environment, there is excellent electric property：Dielectric strength reaches 2 times that 35kV/mm is general material,
Specific insulation reaches 4 × 1016It is 100 times of general material or so；Mechanical strength reaches 2 times that 20MPa is general material.
External insulation layer is the thick low cigarettes of 0.1 ㎜, Halogen, nontoxic, wear-resisting, high flame resistance cross-linking radiation polyolefin material
Material, it is 150 DEG C that the fusing point of this polymeric material, which is 260 DEG C, 180 DEG C are reached using heat-resisting peak and temperature is used continuously,；Tool
There are excellent rub resistance and abrasion resistance properties；There are splendid acid and alkali resistance corrosive nature, oil resistant, even in the elevated situation of temperature
Under still be able to keep stable；Do not produce smog and poison gas under fire hazard environment, oxygen index (OI) reaches more than 35, be 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 can ensure cable electrical performance, outer layer
The fire resistance of cable can be ensured.Because the low cigarette of core interior insulation material, Halogen, nontoxic, high insulating property cross-linking radiation
Polyolefine material, dielectric strength reach 2 times that 35kV/mm is general material, and it is general material that specific insulation, which reaches 4.0 × 1016,
100 times or so of material；Mechanical strength reaches 2 times that 20MPa is general material, have 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 for so both having improved cable, thus subtract significantly
The small external diameter of cable, new-energy automobile high temperature can be used, in narrow space.
The utility model cable is provided with some protuberances in outer jacket outer surface, in practice, the protuberance first with
External contact friction, cable body is just touched after protrusion friction is smooth, this design, friction longevity of oversheath can be increased
Life.Reflective membrane/fluorescent film is pasted outside the utility model oversheath, when overhauling at night, cable can be found first, improves maintenance effect
