Made of high-purity oxygen-free copper core, it delivers excellent conductive performance with low resistance and stable signal and power transmission. The outer thickened insulating layer is tensile, bend-resistant, temperature-resistant and oil-corrosion resistant, avoiding aging cracking, short circuit and open circuit. Precisely made terminals ensure tight plug connection against loosening and falling off. It stably supplies power and transmits control signals to ensure coordinated operation of sensors and actuators, featuring easy wiring and high safety, suitable for all ZF heavy-duty automatic gearboxes.
