<p>PURPOSE:To decrease the surface leakage insulating distance of an insulator and to permit efficient application by conducting an optical fiber from the high tension side to ground side of the insulator so as not to detach the same from the surface of the insulator. CONSTITUTION:An optical fiber is so conducted from the high tension side to ground side of an insulator as not to detach from the surface of the insulator. More specifically, an optical fiber 11 is so conducted as to be passed into an adjacent groove 8a over the crest part 8c of pleats, to run around the groove 8a of the pleats, to be conducted from the side face to the top face of a shade part 8, to run round in the spiral groove 8b on the top surface and to be spirally wound on the outside circumference of a cap 9 by which the fiber is conducted to the adjacent insulator. The surface leakage insulating distance of the insulator is prevented and efficient application is made possible by the above-mentioned constitution.</p> |
