FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, in particular to the use of wires or cables with insulation of silanol cross-linked polyethylene, and can be used in cable industry in production of insulated wires. Method of making an insulated wire or cable consists in the fact that for cross-linking, a conventional container with hot water and vertical loading of drums with a wire or cable is used, but container and cover are made with possibility of their tightness, capable to withstand internal overpressure of up to 1.0 bar, cross-linking is carried out in said sealed container with hot water at an excess pressure created by feeding air inside the container at pressure of 0.2–0.7 bar, cross-linking is carried out in water at temperature of 90–95 °C at excess pressure created by supplying air inside the sealed container for 0.5–1.5 hours.
EFFECT: method combines the advantages of a hot water bath and a steam autoclave and at the same time eliminates the need to discharge the heat carrier during reloading.
