FITTING STRUCTURE OF SUPPORT METAL FOR LIGHTNING PROTECTING INSULATOR IN LIGHTNING-RESISTANT HORN INSULATOR DEVICE

摘要

PURPOSE:To easily fit a lightning protecting insulator without performing the special work on a power transmission line support insulator device by fastening and fixing a support metal on the tip of a support arm with bolts and supporting the lightning protecting insulator on the support metal. CONSTITUTION:A fitting metal 1a is fixed to the tip of the support arm 1 of a tower body with bolts 5. The metal 1a connects support insulators 3A and 3B, the insulators 3A and 3B have electric wire side connecting metals and suspend an electric wire 2, the electric wire side connecting metals support the charge side discharge electrodes. On the other hand, A support metal 28 is fastened and fixed to the tip of the support arm 1 with bolts 5, the support metal 28 supports a lightning protecting insulator 4. A ground side discharge electrode facing the charge side discharge electrode at an aerial discharge gap is provided at the tip of this lightning protecting insulator 4. The lightning protecting insulator 4 can be easily fitted to the support arm 1.
