IEC/BS Standard 3.8/6.6kV XLPE Insulated MV Middle Voltage Power Cable
Application
Suitable for energy networks such as power plants and distribution system etc. Typically used for installation in ducts, underground and outdoors.
Due to its robustness and high electrical stability, medium voltage cables are used in harsh environments.
Note: Red outer sheath can be prone to fading when exposed to UV rays.
Standards
Flame propagation to BS EN60332BS6622IEC 60502
