Production of cable joints

摘要: The invention relates to a method and apparatus for producing an insulated joint between electrical conductors, particularly cables by cross-linked polyethylene material. Heat is applied joined parts of the conductors which have been covered material in uncured condition closely confined within enclosure heated until said cured, pressure being while cooling, whereby voids cured are substantially suppressed. More specifically, cable cores connected together, adjacent portions with material, mould it cooling. Advantageously, form tape. cavity may be defined two moving one them relation other. Alternatively pistons slidable cylinders communicating cavity. In either case through spring means.
