The 18/30kV Three Core Medium Voltage Unarmored Cable is engineered for power transmission and distribution systems in utility networks, industrial facilities, and infrastructure projects operating at a nominal voltage of 30kV.
Thanks to the use of XLPE (Cross-linked Polyethylene) insulation, this cable offers a superior combination of dielectric strength, mechanical durability, thermal stability, and chemical resistance. It is especially suitable for installations where armor protection is not required, but where reliable, long-lasting medium voltage performance is essential.
Whether installed in trays, ducts, or directly underground (where conditions allow), this cable ensures safe and efficient power delivery for medium voltage applications.
