FIELD: electricity.
SUBSTANCE: cable for oil melting (100) comprises a plurality of conductors (102) in assembly. Each conductor in assembly includes a conductor (110) of galvanized steel, an insulating layer (120) that surrounds the conductor of galvanized steel, and a metal shell (130) that surrounds the insulating layer. The armour layer (140) surrounds the plurality of conductors in assembly.
EFFECT: invention provides manufacturing a cable less expensive than conventional heating cables.
