Specifications and functions of 380V three-phase charging cable

China [CN]

Product overview: 380V three-phase cable plays a core role in connecting new energy vehicles, including the following:

1. Efficient transmission of electric energy: Three-phase electricity (L1/L2/L3+N+PE) balances the load and has higher power than single-phase electricity (220V), which is suitable for fast charging piles such as 11kW/22kW, shortening the charging time.

For example: 22kW charging pile (380V/32A) requires three-phase cable, while single-phase cable cannot support this power.

2. Reduce line loss: Under the same power, the current of three-phase electricity is smaller than that of single-phase electricity (such as 22kW single-phase requires 100A, and three-phase only requires 32A/phase), reducing heat and energy loss.

3. Ensure safe operation: High-specification cables are required in high-current scenarios to avoid overheating (such as flame retardant/high-temperature resistant insulation layer) to prevent short circuit or fire.

About specification parameters and their impact:

1. Conductor cross-sectional area (core indicator)

Cross-sectional area vs. current carrying capacity

Of course, taking copper core conductor cable as an example, product specifications can be recommended, please refer to the actual application:

Power (kW) Voltage (V) Current (A/phase) Recommended cross-sectional area (mm²)

11kW 380 16A 4mm²

22kW 380 32A 10mm²

60kW 380 95A 25mm²
