Project Description
Function: Corona proof ring is mainly used on the ADSS cable which is installed with electric power transmission line and whose pressure is over 220KV. Since cable and preformed rods are in the space of high-strength electric field, the terminal end of preformed rods are affected by corona discharge easily which will threat cable’s safe operation. Corona proof can improve the conditions of the electric field greatly, decrease the corona electric erosion to the cable and extend cable’s service life.
