为解决火电厂空冷岛下布置的220 kV架空线耐张绝缘子串在空冷冲洗时的污闪问题，首次将纯瓷绝缘子更换为在高压输电线路上已广泛应用的悬式瓷复合绝缘子，有效增大了爬电距离，保证了绝缘子串的机械性能，避免了纯瓷绝缘子喷涂RTV需后期多次复涂且质量无法控制的缺点，提高了绝缘子串抗污闪能力。
為解決火電廠空冷島下佈置的220 kV架空線耐張絕緣子串在空冷遲洗時的汙閃問題，首次將純瓷絕緣子更換為在高壓輸電線路上已廣汎應用的懸式瓷複閤絕緣子，有效增大瞭爬電距離，保證瞭絕緣子串的機械性能，避免瞭純瓷絕緣子噴塗RTV需後期多次複塗且質量無法控製的缺點，提高瞭絕緣子串抗汙閃能力。

In order to solve the pollution flashover of 220 kV overhead line’s tension insulator strings equipped under the air cooling island of thermal power plant in air cooling washing, it is the first time to replace the pure porcelain insulator with the suspension type porcelain composite insulator that has been widely used on high voltage transmission lines, which effectively increases the creepage distance, ensures the mechanical properties of the insulator strings, avoids the shortcoming of pure porcelain insulator of needing to repeatedly spraying RTV in the later stage after spraying RTV, and improves the ability of insulator strings’ ability to resist pollution flashover.
