Send An Email19/33kV XLPE-insulated medium-voltage power cables are suitable for energy networks such as power stations. For installation in ducts, underground and outdoor. It may also be employed for fixed installations within distribution networks, industrial premises, and power stations. Please note: Red outer sheath can be prone to fading when exposed to UV rays. Medium voltage cables are manufactured using the monosil process. We provide the highly specialized plant, state-of-the-art research facilities and meticulous quality control procedures that are required for the manufacturing of PVC insulated cables for use up to 6KV and XLPE/EPR insulated cables for use at voltages up to 35 KV. The materials are all kept in cleanliness-controlled conditions throughout the production process in order to ensure the absolute homogeneity of the finished insulation materials.
