Normal type disc suspension insulators are appropriate for using in normal area, to increase the number of insulators would enhance the performance of pollution flashover. Insulator is configured by porcelain shell, iron cap and steel pin,
Double-shed type, has the features of smooth shed without edge, open shed shape, large creepage distance, the inner shed smooth. Because this type is designed based on air flow resistance, has the good performance of self-cleaning by wind a
Tri-shed structure, there is increased one small shed between two big sheds. The interspace between big sheds of this tri-shed type, is increased 42% bigger than double-shed type, this improve the resistance of pollution flashover and wet f
For fog type disc suspension porcelain insulator, is used un-synchronism soggy of inner shed and inhibition of discharge by high groove edge under shed, so the artificial pollution flashover voltage is higher, and the anti-pollution perform
Aerodynamic suspension porcelain insulator has big spacer, generally, this is used on the top of suspension string, which is good efficient for preventing bird and anti-penetrated freezing. The shed of aerodynamic disc suspension insulator
Comparing with AC transmission line, DC suspension disc insulator is more stable with less line losses, less line investment, longer transmission distance and higher power. Using in heavy polluted areas, the porcelain material of DC suspens
Possessing the characteristics of both of DC suspension disc insulator and double-shed AC insulator, the double-shed DC anti-pollution suspension disc insulator is used for DC transmission line.
Possessing the characteristics of both of DC suspension disc insulator and tri-shed AC insulator, the tri-shed DC anti-pollution suspension disc insulator is used for DC transmission line.
