Title: Technical Features of High Voltage Three-Phase Cables for Electric Vehicles

Description: The technical features of high voltage three-phase cables for electric vehicles (usually as part of high voltage wiring harnesses) are mainly reflected in the following aspects:

1. High voltage
Voltage range: New energy vehicles generally operate in the B-level voltage range, and high voltage wiring harnesses need to meet the requirements of the operating voltage range of 60V-1500V. According to the provisions of GB/T 184384.3 for Class B voltage, it is usually AC30V-1000V or DC60V-1500V. As a key part of power transmission, the high voltage three-phase cable of electric vehicles also needs to withstand such high voltage.

2. High current
Current load: The motor of an electric vehicle requires a large amount of current to operate normally, so the high voltage three-phase cable must be able to withstand a large current load. The rated operating current of the DC bus can usually reach more than 200A, or even higher, to ensure efficient transmission and stability of electrical energy.

3. Safety
Electrical safety: The high voltage three-phase wiring harness needs to have high safety performance to prevent leakage, short circuit and other faults in the electrical system. This includes the use of high-quality insulation materials, reasonable wiring harness layout and connection methods, etc. to ensure the safe operation of the electrical system.

In summary, the technical characteristics of electric vehicle high-voltage three-phase lines are mainly reflected in high voltage, high current, sealing, heat resistance, electromagnetic compatibility, durability, safety and high-voltage connector characteristics. These characteristics jointly ensure the stable, reliable and safe operation of the high-voltage electrical system of electric vehicles. Welcome to consult customer service: OMG EV battery cable
