Medium Voltage Cables (1kV – 33kV)

Medium voltage power cables designed for substation distribution networks and interconnection between 1kV and 33kV. Equipped with XLPE insulation, semi-conductive layers, and metallic screens for uniform electric field distribution, with optional mechanical protection via armouring. These cables provide stable electrical performance, continuous operating temperature up to 90°C or more, and reduced fault currents due to metallic screens and semi-conductive layers. Ideal for urban substation networks, connecting distribution stations, and underground or central duct installations.
