The Three Core 12/20kV Medium Voltage Unarmored Cable is designed for electricity transmission and distribution networks, particularly in fixed installations such as industrial plants, utilities, and infrastructure projects.
This cable features XLPE (cross-linked polyethylene) insulation, which offers excellent electrical, thermal, and mechanical properties, along with chemical resistance. It is lightweight, easy to install, and ideal for indoor and outdoor use where armor protection is not required.
