Abstract
PURPOSE: To form electrically and mechanically excellent junction by forming a reinforced insulator on junction and then by covering it with a protective cylinder which serves as a fluid container for pressurizing and heating the fluid inside.
CONSTITUTION: An insulating tape of unvulcanized ethylenepropylene rubber or unbridged polyethylene is wound around the junction 5 of conductor to form the reinforced insulator 1. Then, the fluid seal layer 6 is provided on the insulator 1 and then the protective cylinder 2 is covered on the seal layer. Then, the fluid 10 is forced by pressure into the protective cylinder 2, and then heated by the heater 11 attached to the outside of the protective cylinder 2 to mold the reinforced insulator 1. Then, the protective cylinder 2 is transferred to remove the fluid seal layer 6, and then a necessary surface treatment is made. Again, the protective cylinder 2 is attached and the insulating mixture 12 is filled in the cylinder 2 to reinforce the insulated junction. Thus, the sealing work is easy and also electrically and mechanically excellent junction can be obtained.
