Wire for field communication of P-274M grade

Field communication wire consists of two twisted insulated conductive cores. The conductive core is formed by twisting of copper and steel galvanised wires with diameters of 0,30 mm. The twisting system of the conductive core is as follows: 1+6 (Copper wires should be in the outer strand: 2 copper + 1 steel + 2 copper + 1 steel). The conductive cores are covered with polyethylene insulation. The wire is designed to be suspended on the supports of overhead lines or local objects, for laying in the ground, on the ground. Short-term laying through water barriers is allowed.
