What is the difference between high-voltage cables for new energy vehicles and household cables?

Generally speaking, the thicker the cable, the more current it can carry. Some friends are curious whether the car cable is the same as the household cable? Of course not the same, now let's talk about the main difference between the two lines.

1. Conductor. The conductor of the high-voltage cable for new energy vehicles is made of multiple copper wires, while the conductor of the household cable is a solid copper core. The electric vehicle high-voltage cable is the carrier for transmitting electric energy and needs to have strong electrical conductivity. By increasing the number of conductor cores, the electrical conductivity of the wire harness can be enhanced.

2. In terms of cross-sectional area. The cross-sectional area of ​​high-voltage cables for vehicles is generally several times that of household cables. The former is thicker because it needs to carry a larger voltage. Considering the layout in the car, the toughness and rigidity of high-voltage cables are required. Compared with A solid copper core, multi-core wire is also a better choice.

3, the shielding layer. Automotive high-voltage wiring harnesses have shielding, while household cables do not. Because a magnetic field is generated when there is current in the conductor, and the high-voltage cables are distributed inside the car, it is necessary to shield the magnetic field in the wiring harness by adding a shielding layer, and reduce the influence of electromagnetic radiation on other components, and also need to shield the interference of external magnetic fields .

All in all, high-voltage cables are used in harsher environments, so their standards are more stringent. When purchasing high-voltage wire harnesses, we need to choose safer and more durable cables in terms of design and materials. Paige Rui specializes in the production of new energy electric vehicle wiring harnesses. The EV high-voltage wiring harness adopts XLPE insulation and sheath, uses tinned copper and braided shielding structure, and has a temperature resistance level of -40°C-150°C. Product aging test, The flame test, oil resistance test, tear resistance and other tests all meet the relevant standards and are a good choice.
