Twisting prevention tool of the double row suspension insulator string with a suspension-type lightning protection insulator

摘要

(57) [summary] [purpose] it is possible to apply a twisting preventer on insulator device equipped with a suspension type lightning insulator, reliably prevent twisting of the suspension type lightning insulator string due to vibration, such as wind or earthquake to. [Configuration] and the first clamping bracket unit 22 and the second clamping bracket unit 23 is connected by a connecting member 24, cap fitting 10 of said clamping bracket unit 23, suspension type lightning protection insulator 5A The first clamping ring segments 33 and the second clamping ring segments 34 which are bypassed are annularly arranged, respectively provided on both ring segments 33 and 34, the reinforcing ribs 18 formed in the lower portion the cap fitting 10 a pair of pressure plates 39.40 to be in contact, It is constituted by a bolt 37 for connecting the two clamping ring segments 33 and 34 each other.
