Understanding 4 Câble AWG
UN 4 Câble AWG is a standard conductor size defined by the American Wire Gauge (AWG) system. It is widely used in electrical systems due to its balance between conductivity, force mécanique, and installation flexibility.
Key parameters of 4 Câble AWG:
- Cross-sectional area: approximately 21.1 mm²
- Diamètre du conducteur: about 5.2 mm
- Typical ampacity: 85–95 A (depending on insulation and installation conditions)
This size is commonly applied in both low voltage and medium voltage systems with different structural designs.
