Embodiment 1
[0038] See figure 1 , The aluminum alloy cable for new energy vehicles of Example 1 includes a conductor 1, an insulating layer 2, a shielding layer 3 and a sheath layer 4 arranged in sequence from the inside to the outside.
[0039] Conductor 1 is a solid aluminum alloy conductor with a cross-sectional area of 1.5mm 2 , can greatly reduce crimping or welding defects when the stranded conductor 1 is connected to the terminal. The solid aluminum alloy conductor adopts a high temperature resistant aluminum alloy formula system, and the composition and ratio are calculated in parts by mass: Al96.5%, Mn0.6%, Cu0.2%, Fe0.6%, Si0.6%, Mg1.5 %. Its elongation at break and heat resistance are excellent, and it can operate at 150°C for a long time without deformation and has high breaking strength.
[0040] The shielding layer 3 is an aluminum pipe shielding layer.
[0041] Both the insulating layer 2 and the sheath layer 4 are solid-solution materials of PTFE and rubber, and both...
