FIELD: electricity.
SUBSTANCE: electric cable includes current-conducting cords insulated with thermoplastics and sheath from thermoplastic elastomer, which is located on each cord and/or on all together; at that, cord insulation is made from oxygen-free-radiation-modified thermoplastic material through sheath, and sheath is made from thermoplastic elastomer soaked with non-saturated hydrocarbons. Saturation of insulation from thermoplastic material with non-saturated hydrocarbons also improves cable characteristics. Gap made between insulated cords in cable with common sheath increases its operating life.
EFFECT: longer operating life of cable at operation in contact with corrosive medium.
