<p>PURPOSE:To prevent bedewing and to conduct a premolded insulator mounting work easily by providing a hydraulic cylinder, fastening metal fittings and pressing metal fittings and by mounting the premolded insulator by means of the hydraulic cylinder with the inside of a cover filled with electric negative gas or dry air after degassing the inside of the cover. CONSTITUTION:An end of a CV cable 12 is peeled at places to expose a cable conductor 15, which is covered with a conductor connection sleeve 16 and is compression-connected. After the inside of a cover 4 is degassed, the atmosphere of the inside of the cover 4 is replaced with SF6 gas, etc., by using a gas filling tube 21. Then, a hydraulic cylinder 10 installed on a fastening metal fitting 7 is driven and a cone-shaped end of a premolded insulator 2 is moved to the right through a pressing metal fitting 3, to be fit in with a tapered face on the inner surface of an epoxy unit 1. After removing an insertion jig, a spring unit 18 is mounted on an end of a protective tube 17 and the spring unit 18 is covered with an end copper pipe 19. A part between the end copper pipe 19 and the CV cable 12 is coated with a waterproof agent 20.</p> |
