What's the Electric Wire of the Car?

As the "neural network" of automobiles, wire and cable for vehicles are core components that ensure the normal operation of electrical systems by transmitting power and signals. Different from ordinary wires, automotive wire and cable must meet strict requirements for heat resistance, flexibility, and anti-interference to adapt to complex working environments such as high temperatures and vibrations. Below is a detailed elaboration.

1. Basic Definition of Automotive Wire and Cable

Automotive wire and cable refer to assembled components consisting of conductive cores, insulating layers, and terminals. The conductive core is usually made of multi-strand copper to ensure conductivity and flexibility, while the insulating layer is made of high-performance materials like cross-linked polyethylene to resist high temperatures and corrosion. Their core role is to connect power sources (batteries, generators) with electrical components (engines, lights, sensors) and transmit control signals between them, directly affecting vehicle safety and performance.

2. Main Classifications of Automotive Wire and Cable

2.1 Power Wires

These thick wire products carry large currents, mainly connecting batteries to engines and generators. They feature excellent conductivity and can withstand high temperatures up to 120-150℃, ensuring stable power supply for high-power components.

2.2 Signal Cables

Thin-diameter cable designed for transmitting weak electrical signals, such as those from ABS, radar, and infotainment systems. Most adopt shielding structures to avoid electromagnetic interference, guaranteeing accurate signal transmission.
