1. Power and signal transmission
The seven-core cable is responsible for the transmission of power and signals in the Trailer/Truck. It connects different systems of the vehicle, such as lighting, braking, steering, signaling, etc., to ensure that these systems can work properly. The seven-core design improves the transmission capacity of the cable and meets the needs of complex electrical systems.

2. Improve system reliability and safety
Since the Trailer/Truck needs to face various complex road conditions and working environments during driving, the reliability and safety of its electrical system are crucial. The use of the Trailer/Truck seven-core cable reduces the risk of the entire system being paralyzed due to a single cable failure by providing multiple independent transmission channels, thereby improving the overall reliability and safety of the system.

3. Durability and resistance to environmental interference
Seven-core cables are usually made of high-quality insulation and sheath materials with good durability. They can withstand harsh weather conditions, corrosive substances and mechanical wear, ensuring stable performance during long-term use. In addition, the shielding layer is used to isolate the conductors of the seven-core cable, which can effectively prevent the signal from being affected by external electromagnetic interference and ensure the accuracy and stability of signal transmission.

4. Wide adaptability
Seven-core cables are widely used in various Trailer/Truck electrical systems, including but not limited to lighting systems, braking systems, signal systems, and power supply for certain special equipment (such as air conditioners, refrigerators, etc.). This wide adaptability makes seven-core cables an indispensable and important part of Trailer/Truck electrical systems.

5. Application in specific scenarios
In certain specific scenarios, such as underground coal mines, nuclear power plants, and other environments that require high safety and stability, the flame retardant and aging resistance of seven-core cables are particularly important. These properties can ensure that the cable can still work normally in harsh environments, providing reliable protection for the operation of equipment.
