Automotive wires are the key components used to transmit power and signals in automotive electrical systems, and are responsible for connecting batteries, generators, sensors, control units, lights, motors and other devices. Due to the complex automotive environment, automotive wires need to have high temperature resistance, oil resistance, vibration resistance, corrosion resistance and other characteristics.

Main features of car wire:

1. High temperature resistance : the engine compartment temperature is high, and the wires need to be able to work at -40°C to +125°C or even higher temperatures.

2. Oil resistance and chemical corrosion resistance : need to resist the corrosion of oil, fuel, detergent and other chemical substances.

3. Resistance to vibration and mechanical stress : the vibration of the car is frequent, and the wire needs to have good vibration resistance and mechanical strength.

4. Wear resistance : the outer cover of the wire should be wear-resistant to prevent damage due to friction during long-term use.

5. Good electrical performance : It is necessary to have stable conductivity and insulation to ensure reliable signal and power transmission.

6. Flame retardant : need to have flame retardant performance to prevent fire.

Common types of car wires:

1. Low-voltage wire : used to transmit low-voltage electrical energy, such as batteries, lights, sound, etc., common cross-section area of 0.5mm² to 6mm².

2. Signal wire : Used to transmit signals of sensors and control units, usually shielded lines to prevent electromagnetic interference.

3. High voltage wire : High voltage system for hybrid and electric vehicles, voltage up to hundreds of volts, higher insulation requirements.

4. Coaxial cable : used to transmit high-frequency signals, such as antennas, GPS, etc.

Material of car wire:

1. Conductor material : usually copper or copper alloy, with good electrical conductivity and flexibility.

2. Insulation material : Commonly used PVC, crosslinked polyethylene (XLPE), silicone rubber, etc., with heat resistance, oil resistance, corrosion resistance and other characteristics.

3. Sheath material : Used to protect wire, commonly used PVC, TPE, etc., with wear resistance, oil resistance, flame retardant and other properties.

Car wire application:

1. Engine system : Connect sensors, ignition systems, injectors, etc.

2. Body electrical system : Connect lighting, sound, air conditioning, electric Windows, etc.

3. Chassis system : Connect ABS, ESP and other control systems.

4. Hybrid and electric vehicles : Connect high-voltage components such as batteries, motors, and electronic control systems.

Standard for car wires:

Automotive wires must comply with international and industry standards such as ISO 6722, SAE J1128, etc., to ensure their performance and safety.

In short, the automotive wire is the core of the automotive electrical system, which needs to have high temperature resistance, oil resistance, vibration resistance and other characteristics to ensure the reliable operation of the car in a variety of environments.
