Description
Technical field
The invention belongs to electric automobile and technical field of cables, especially relate to a kind of electric automobile inside high tension cable, especially relate to use the cable of aluminium alloy conductor.
Background technology
It is a kind of for electric connection line, the primary high-voltage transmission for vehicle interior that automotive interior high pressure connects cable.Communication power supply flexible cable does not require nothing more than has good flexibility, in order to conveniently lay in narrow space or when similar, and requires have desirable anti-flammability, to adapt to higher fire-protection rating requirement.
The application number of our company is: 2014104424205 and name be called: " connecting cable and preparation method thereof with high pressure inside a kind of electric automobile with super soft aluminium conductor ", application number be: 2014104424313 and name be called: " have inside the electric automobile of super soft aluminium conductor and connect cable and manufacture method with high pressure ", application number be: 2014104424328 and name be called: in " there is electric automobile internal pair sheath high pressure connection cables and the manufacture method of ultra-soft aluminum conductor " patent, adopt aluminium conductor to substitute copper conductor, reach the purpose of joint Zhi Jiangben；But, owing to the hardness of aluminum is not high, although the purpose of softness can be reached, but its tensile property is poor, is easier to creep, corrosion resistance and thermal expansion aspect not ideal enough.
