Product Description

Shielding Grading rings is applied when constructed the nation's first 330kV transmission line. As it combined grading rings and shielding rings(shielding rings applied in above 330kV voltage transmission line and substation, as the voltage is very high, when the electric potential gradient of conductor and fittings surface is greater than critical value, corona discharge occurred. Corona discharge will interfere the radio, also will consume the certain electric quantity. After installed the shielding rings, it will form a uniform electric field, and forbid corona discharge occurred), so it is called Shielding Grading rings. Then, it is been largely used in 500,750,±800kV or even 1000kV projects.
