Low-voltage automotive cable compounds: a key element of automotive electrical systems

From an electrical performance perspective, low-voltage automotive cable compounds must ensure good conductivity. Highly conductive materials such as copper are often used for conductors, and the resistance is further reduced by carefully formulating the compound. This effectively reduces energy losses during the transmission of power to many electronic devices in the car, such as lighting and multimedia systems. At the same time, insulation performance is also a key factor. Compounds made of materials such as polyethylene and polyvinyl chloride can effectively prevent current leakage. Whether in wet weather or dry environment, their stable dielectric constant and high resistivity ensure the safe operation of the electrical system in the car.

In terms of mechanical properties, cable compounds must be flexible. The internal structure of the car is complex, and the cable needs to shuttle through it, so it must be able to adapt to various bends and twists. For example, in some compact car engine compartments, the wiring layout is difficult, and cables with good flexibility can easily cope with it. In addition, tensile strength should not be ignored. Vibration, acceleration, braking and other actions during the driving process of the car will exert tension on the cable. Compounds with sufficient tensile strength can prevent the cable from breaking in these situations.

Thermal performance is also an important consideration. The temperature of the car engine compartment is high, and some areas will also have large temperature changes. Cable compounds must be able to remain stable in high temperature environments. Compounds made of materials such as polyamide can work normally at higher temperatures. In addition, good heat dissipation is also critical to avoid danger caused by overheating of the cable.

In traditional fuel vehicles, low-voltage automotive cable compounds are widely used in systems such as starting, ignition, fuel injection, and line connections of various sensors. For electric vehicles and hybrid vehicles, battery management systems, motor control systems, etc. have higher requirements for cable compounds because they involve large current transmission and more complex electrical control.

Low-voltage automotive cable compounds are also developing in an environmentally friendly direction. Lead-free and halogen-free compounds are gradually becoming mainstream, which not only meets environmental protection requirements, but also improves the safety of vehicles. With the development of autonomous driving technology and the widespread application of high-performance electronic systems, cable compounds also need to meet the low attenuation and high bandwidth requirements of high-speed data transmission, and have stronger anti-electromagnetic interference capabilities. In short, low-voltage automotive cable compounds continue to evolve in the development process of the automotive industry to adapt to new needs.
