Title: Prefabricated connection for cv cable
Inventor: NIINOBE HIROSHI
IPC: H02G15/08
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To make it possible to make full use of the insulating capability with stability for a long time, by forming a smooth section of a specified length in the center of the removed section through two-staged grinding when the end of a cable outer conductor is removed into a tapered shape. SOLUTION: An end of a cable outer conductor is ground to form a first tapered portion 12a1 , a smooth portion 12a2 , and a second tapered portion 12a3 on the cable outer conductor 12a. Before assembly on the site, silicone oil is applied to the surface of a cable insulator 12 and the inner and outer surfaces of a rubber molded stress cone 16, and the stress cone is fit onto the cable. Thus most silicone oil is let out, and a very small quantity of silicone oil is caught in the boundary between the stress cone 16 and the cable insulator 12. If a pressure is applied to the boundary, the very small quantity of silicone oil moves into the gap between the inner surface of the stress cone 16 and the end of the cable outer conductor 12a to form a silicone oil sump there.  Since the smooth section is formed in the center of the end by two-staged grinding, however, the sump of silicone oil can be reduced. As a result, stable insulating capability is obtained for a long time.
