IEC/BS Standard 18-30kV-XLPE Insulated MV Middle Voltage Power Cable

Application

Suitable for energy networks such as power stations,distribution system etc. It usually 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.
