Description
Technical field
The invention belongs to technical field of cables, especially relate to a kind of internal use of electric automobile with super soft aluminium conductor
High pressure connection cable and preparation method thereof.
Background technology
Automotive interior high pressure connection cable is that one kind supplies electric connection line, the primary high-voltage transmission for vehicle interior.Logical
Letter power supply flexible cable does not require nothing more than has good flexibility, so that convenient in narrow space or in the case of similar apply
If, and require that there is preferable anti-flammability, required with adapting to higher fire-protection rating.
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；
Generally carried out with flexible cable substituting using communication power supply both at home and abroad and use.
Technical information with regard to communication power supply flexible cable can be in disclosed Chinese patent literature, such as
Cn201247632y recommends have " communication power supply fire-retardant, fire resisting, shielding anti-interference flexible cable ", cn201302849y to be provided with
" a kind of communication power supply flame-retardant refractory flexible electric cable ", cn202230791y are disclosed a kind of " the poly- second of communication power supply flame-proof cross-linking
Alkene insulated cable ", cn202720953u introduce have " for the shoe flame-retardant shielding flexible cable of communication power supply ",
Cn202855416u discloses " communication power supply fire-resistant shield flexible cable " and a kind of disclosed " communication power supply of cn202601277u
With flame-retardant flexible electric cable ", etc..
