Document Type and Number:
WIPO Patent Application WO/2010/057422
Kind Code:
A1
Abstract:
An insulator capable of improving the electrical strength of external insulation. An upper barrier (1) and a lower barrier (2) are arranged outside an upper electrode (8) and a lower electrode (9) of the insulator. A middle barrier (3) is arranged outside cascading electrodes of an insulator string. An upper ring barrier (4) and a lower ring barrier (5) are arranged outside an upper equalizing ring (10) and a lower equalizing ring (11) of the insulator which has the upper equalizing ring (10) and the lower equalizing ring (11). An iron tower barrier (6) and a transmission line barrier are arranged nearby an iron tower (12) and transmission lines close to the insulator.
