IEC/BS Standard 19-33kV-XLPE Insulated MV Middle Voltage Power Cable

Medium voltage cables(MV) are manufactured using the Monosil process. We offer the highly specialized factories, leading research facilities and exacting quality control procedures necessary for the manufacture of PVC insulated cables up to 6KV and XLPE/EPR insulated cables for use at voltages up to 35 KV. Throughout the production process, all materials are kept under clean controlled conditions to ensure absolute homogeneity of the finished insulation material.

Application

Suitable for energy networks such as power plants,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: The Red outer sheath can be prone to fading when exposed to UV rays.
