P-274U field communication wire

Field communication wire consists of two twisted insulated conductive cores. The conductive core is formed by twisting copper and galvanised steel wires. The twisting system of the conductive core is as follows:1+6 (Central steel wire with a diameter of 0.40 mm+2 copper wires + 1 steel wire +2 copper wires + 1 steel wire with a diameter of 0.30 mm). The conductive cores are covered with polyethylene insulation. The wire is designed for suspension on overhead line supports or local objects, for laying in the ground, on the ground. Short-term laying through water barriers is allowed.
