Abstract
An insulated conductor such as an encapsulated electrical circuit is made by locating the circuit components in a preformed carrier with opposed flexible walls with an external, outwardly facing abutment in the shape of a conical opening through each wall. The internal volume between the walls of the carrier is then filled with a hot fluid insulating plastic which also fills the conical opening forming a bridge between the openings. The bridge is caused to cool and set first so that it contracts developing a lengthwise tension which draws the walls toward each other providing the formation of air space between the walls and remainder of the filling.
