Types of the automotive wiring

Lead Wire

The lead wire is convenient in joints with multiple connections. The presence of a single cable in a box makes it easier to make internal electrical connections.


AVSS wires are thin-walled, have many stranded conductors and bending properties. Besides, they are resistant to both fire and heat. That makes them withstand the adverse engine environment.


The FLYY can accommodate thin walls and low-voltage typical in the automotive industry.

Applications of Automotive Wire

Automobiles apply a wide range of wire harnesses for the highest possible performance. These wires combine the wiring of various electrical and electronic equipment into one system. The integration injects efficiency into a vehicle’s power and signals transmission system.

We customize and manufacture these products according to a customer’s electrical and geometrical needs. You can embed these wires into your car’s body, sliding doors, power windows, engine, and others.
