Multicore copper round conductors (not less 5 class in accordance with GOST 22483 – 77).
Insulation of main and auxiliary conductors
Polyvinylchloride (PVC) compound of low hardness.
Screen over main conductors
Earth conductor is divaricated on individual cores and consists from three cores; the total cross-section is not less than 10 mm².
Elastic screen from electroconductive compound laid over each of the individual cores of earth conductor.
Four insulated auxiliary conductors and three screened earth conductors are twisted together in cable core. The elastic screen from electroconductive compound is laid over the cable core.
Main insulated conductors stranded around screened cable core.
Intervals between screened cable core and main conductors are filled by insulated cable bundles of synthetic thread during twisting.
Two-layer polyvinylchloride compound of low hardness oversheath is laid over stranded conductors of cable. Oversheath is reinforced by steel-copper braid.
Upon customers request allow strengthening cable oversheath by another materials do not impairing the strength characteristics of the cable.
