The automotive cable standards mainly cover a series of key technical and safety requirements to ensure the performance and quality of the cables, thereby improving the safety and reliability of the car. These standards include but are not limited to wire cross-sectional area, color identification, insulation thickness, high temperature resistance, flame retardancy, elasticity retention, corrosion resistance and other aspects. In addition, there are specific national and international standards, such as GB/T 25085-2010, GB/T 25087-2010, GB/T 25089-2010 and DIN/TS 70112-1:2024, which specify specific requirements and test methods for automotive cables.
Wire cross-sectional area: Common specifications for automotive wires include 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0 square millimeters, etc. Wires of different specifications are used for wires of different power electrical equipment and have different load current values .
Color identification: The color identification of automotive wires should comply with relevant standards, such as the surface color of the insulation layer of single-color wires is black, the color of the phase line is the main color of multi-color wires, and the other colors are auxiliary colors.
Insulation layer thickness: The thickness of the insulation layer of automotive wires should meet the requirements to ensure the insulation performance of the wires during use.
High temperature resistance: Automotive wires should have high temperature resistance and be able to work normally in the high temperature environment of the car engine compartment.
Flame retardant performance: Automotive wires should have flame retardant properties, which can effectively prevent the wires from burning in fires and other situations, reducing the possibility of fires.
Elasticity retention performance: Automotive wires should have good elasticity retention performance, and be able to maintain their shape and performance in situations such as car vibration and bending.
Corrosion resistance: Automotive wires should have corrosion resistance and be able to resist the erosion of corrosive substances such as acids and alkalis inside the car.
In addition, there are some specific national and international standards, such as DIN/TS 70112-1:2024, which is the latest standard officially released by the German Standardization Committee in March 2024, and specifies the tests and requirements for copper conductor unshielded single-core cables. The release and implementation of this standard is of great significance for regulating and promoting the healthy development of the automotive wire and cable industry.
