FIELD: electricity.
SUBSTANCE: cable comprises current-conducting strands from a round copper wire with insulation from fire-resistant organosilicic rubber, which are twisted in pairs jointly with insulating cords from water-blocking threads, on top of which a screen is laid from laminated aluminium foil with a metal layer outside and braids from copper tinned wires applied evenly above the laminated aluminium foil. Screened pairs of the cable with pair number of 2 or 4 are twisted into a core. The inner space of the cable core is filled with sealing compound and enclosed into a shell from a polymer composition that does not contain halogens.
EFFECT: increased resistance of a cable to exposure of open frame under single mechanical shock, preservation of cable operability after fire liquidation under long-term exposure of sinusoid vibration, increased ability of a cable to resist action of longitudinal hydrostatic water pressure.
