FIELD: mining.
SUBSTANCE: cable consists of one or several isolated leads coated with one or two, or three pairs of armored layers and with exterior polymer coating; also each layer of exterior pair is executed with lay length equal to 8÷12 multiple diameter of laid layer with gaps between wires providing 60-70% filling of layer from close laying, while rest free part (30-40%) of both layers of armor of exterior pair is filled with polymer material of exterior coating.
EFFECT: increased tear resistance of cable on a whole and adhesion hardness of polymer coating to surface of wires of exterior pair of armor; increased corrosion protection of cable from aggressive well fluid.
