Abstract: Apparatus for molding insulation about a relatively short section of an uninsulated conductor of a high voltage cable. The apparatus has a pair of mold forms that define a cavity in which the new insulation is molded. Heat and pressure applying platens on each side of the mold forms are fitted with perpendicularly extending stress bars and removable means mounted to the platen for biasing the latter and, therewith, the mold forms towards each other. The mold forms and at least one platen include a series of cavity vent holes which are tapered and have a major diameter proximate the cavity. A transfer pot is provided for injecting a softened insulating material into the cavity via a passage. One or move transverse bars extend across the center of the passage and prevent entrapped gas or air disposed in the center of the transfer pot from being transferred into cavity. A band heater is applied about a length of cable contiguous with and extending from the mold forms to avoid the formation of permanent bulges in existing cable insulation during the application of heat and pressure to the new insulating material in the mold form cavity.
