Introduction to 380V cable material selection
China [CN] General insulation materials for copper core cables: XLPE (cross-linked polyethylene): high temperature resistance (90℃~105℃), anti-aging, suitable for fixed laying (such as YJV cable).
Rubber insulation (such as EV cable): good flexibility, suitable for mobile charging gun wire.
Cable structure: 5-core cable (three-phase + neutral wire + ground wire):
Typical model: YJV-5×6mm² (3-phase + 1N + 1PE), for fixed installation.
Shielding layer: anti-electromagnetic interference (especially DC fast charging high-frequency signal).
Voltage level: Nominal voltage: 380V, but you need to choose a cable with a withstand voltage ≥1000V (to deal with instantaneous surges).
Application scenario and specification matching: home/commercial AC pile (11kW/22kW)
Short distance (<30 meters): 4mm² (11kW), 10mm² (22kW).
Long distance (>50 meters): need to upgrade the cross-sectional area (such as 16mm² for 22kW long distance).
DC fast charging pile (above 60kW)
Requires 25mm² copper cable + liquid cooling technology (such as Tesla V3 supercharger).
Summary: No matter how large the cable is, please understand the cable specifications and models according to actual needs. Welcome to: https://www.omgevcable.com
