<p>PROBLEM TO BE SOLVED: To provide a strain insulator device 1 to which lightning arresters 6a and 6b are mounted while being balanced, while having a structure of decreasing reduction in strength and durability of brackets 5a and 5b.SOLUTION: In a structure for mounting lightning arresters to a plurality of strain insulator series 2, lightning arresters 6a and 6b are divided into a ground side and a charged side with a substantially equal mass and mounted to different strain insulator series 2 while being balanced. Thus, the strain insulator device 1 can be prevented from being twisted. Further, by installing the lightning arresters 6a and 6b having a substantially half mass in comparison with conventional lightning arresters in both ends of the strain insulator series 2, load stress to brackets 5a and 5b is reduced and damage risk of the brackets 5a and 5b is decreased.</p> |
