Insulator device for power transmission line

Abstract

Abstract PURPOSE:To monitor the state of a power transmission line through an optical fiber by providing hollow insulator which has the optical fiber for the state detection of the power transmission line in a hollow part between a high-voltage and a low-voltage side by connecting both ends of the hollow insulator through flexible metallic connectors. CONSTITUTION:The power transmission line 3 is suspended and supported from and by a steel tower arm 2 by the power transmission line insulator device which has a normal insulator string 4 and a hollow glass run 6 with the optical fiber 5 in its hollow part connected in parallel between upper and lower yokes 7 and 8. The hollow insulator string 6 is formed by connecting flexibly plural hollow insulator pieces 10 which each have the optical fiber 5 for the state detection of the power transmission line 3 in a hollow part mutually through metallic connectors 11, and the optical fiber 5 transmits information on the state of the power transmission line 3 which is detected by an optical sensor 12 fitted onto the power transmission line 3 to an overhead earth-wire 15 made of an optical fiber compound cable.
