FIELD: electrical engineering.
SUBSTANCE: method for production of insulated HV direct current (DC) eclectic cable or HV direct current (DC) eclectic cable or HV direct current (DC) lead or HV junction involves the stages of a polymer-based insulation system production (21), the system including a stirred polymer composition (12). Further thermal treatment (25) of the polymer-based insulation system is performed until the outside surface of the polymer-based insulation system is coated (24) with a coating impermeable for the substance present in the polymer-based insulation system as evenly distributed. Thus the concentration of the substance in the polymer-based insulation system is levelled.
EFFECT: manufacture time reduction, electric strength enhancement and maintenance simplification.
