Title: Insulator skirt fitting for overhead cable - uses pulley attached to clamp which grips outer edge of skirt to support cable before it is placed round insulator
Inventor: GAMET LUCIEN
IPC: H02G1/04
Filed: 1980-11-04
Abstract: The device has a demountable clamp which is fastened round the edge of the insulator skirt and carries a pulley wheel over which the insulated overhead cable is run. The cable is tensioned while on the pulley then lifted off the pulley and placed round the insulator. This takes away risk of damage by pulling the cable round the insulator while tensioning. A yoke with jaws filled with hard rubber notches fits over the edge of the insulator. A hoop is pivoted from the two ends of the yoke, and has a hard rubber insert so the hoop may be pulled down over the outer edge of the insulator, completing the gripping of the skirt edge. The vertical cable pulley runs on a shaft fitted to the yoke, carrying the cable till it is shifted over to the insulator.
