Description

Application

HVCRC CENTELSA by Nexans cables are designed to improve the current capacity of the line, reduce sag and electrical losses and are used in overhead lines for the transmission of electrical energy. Additionally, they are an excellent alternative for transmission line repowering projects.

Construction

Conductor made of trapezoidal wires of high-conductivity annealed aluminum alloy 1350-O, stranded on a carbon and glass fiber core embedded in a high-temperature thermoset resin.
