Cables passing through the interior of the vehicle can generally be divided into two voltage categories - low voltage, between 0 and 60 V, and high voltage, which usually means any voltage higher than 60 V (usually operating up to 600, 800 or 1500 V electric vehicle industry).

The structural design and key performance of high-voltage cables are particularly important in the overall cable. Differences in all aspects are based on differences in materials, while excellence is determined by the key performance of materials.

The flexibility of high-voltage cables for electric vehicles depends largely on the design of conductors. High-voltage cables adopt special conductors. A large number of very fine diameter monowires are used to lay a certain number of strands, and then concentric twisted pairs are used to form the flexible conductors required for high-voltage cables. Achieve flexible performance. At the same time, another advantage of the multiple is that the bending resistance is better, the stranding pitch is shorter, and the bending life of the harness can also be improved.

The reason is that the conductivity of copper is better than that of aluminum, which makes the braided net better in transmitting electromagnetic noise. Therefore, as a shielding layer, woven mesh often has better shielding effect. If you want to know which specification and model should be selected.
