METHOD FOR PRODUCING INSULATED WIRE OR CABLE Russian patent published in 2007 - IPC H01B13/06 

FIELD: electrical engineering; using silanol cross-linked polyethylene covered wires or cables.

SUBSTANCE: proposed method includes covering of cable or wire conductor with silanol cross-linked polyethylene insulation followed by cooling down wires or cables and placing them in horizontal branches into water-filled basket. After that either current is passed through cable or wire thereby heating it to temperature not over maximal admissible value ensuring insulation resistance to thermal deformation and exposing it to this temperature for period required for silanol cross-linking of polyethylene, or basket is placed in heated tank filled with water, steam, or steam-water mixture, and held in this tank at mentioned temperature for time required for polyethylene cross-linking, or water is drained from basket and then the latter is placed in heated tank filled with water, steam, or steam-water mixture and held in this tank at mentioned temperature for time required to ensure silanol cross-linking of polyethylene.

EFFECT: enhanced quality of insulation, reduced cost, time, and heat energy requirement.
