Description
Technical field
The invention belongs to technical field of cables, especially relate to inner two sheath high pressure stube cables and the manufacture method used of electric automobile with ultra-soft aluminum conductor.
Background technology
Automotive interior is a kind of for electric connection line with high pressure stube cable, the primary high-voltage transmission for vehicle interior.Communication power supply not only requires to have good flexibility with flexible cable, to conveniently lay under situation, and requires to have desirable anti-flammability in narrow space or similarly, to adapt to higher fire-protection rating requirement.
The cable for car overwhelming majority adopts copper conductor both at home and abroad at present, and copper conductor itself is heavier, and flexibility is poor; Conventionally adopt communication power supply to substitute use with flexible cable both at home and abroad.
About communication power supply, by the technical information of flexible cable, can in disclosed Chinese patent literature, be seen in, for example CN201247632Y recommends to have that " communication power supply is with fire-retardant, fire-resistant, shielding anti-interference flexible cable ", CN201302849Y provides " a kind of communication power supply flame-retardant refractory flexible electric cable ", CN202230791Y discloses " the flame-retardant crosslinking polyethylene insulated flexible cable of a kind of communication power supply ", CN202720953U introduces to be had " for watt form drag combustion shielded flexible cable of communication power supply ", CN202855416U discloses " communication power supply fire-resistant shield flexible cable " and CN202601277U disclosed " a kind of communication power supply flame-retardant flexible electric cable ", etc..
