FIELD: electrochemical industry; power cables for feeding submersible motors of oil pumps.
SUBSTANCE: proposed cable has current-conductors covered with first and second insulating layers, as well as protective pad and armor common for all conductors. Insulation is made of fluorine-containing copolymers which enhances cable thermal stability to 230 °C.
EFFECT: reduced mass and size, enhanced thermal stability of cable.
