CAP AND PIN TYPE SUSPENSION INSULATORS
TOUGHENED GLASS SUSPENSION INSULATORS
DC disc suspension porcelain insulators are used on HVDC transmission lines to support and insulate conductors. The insulators can be used in heavy polluted area with reasonable shed profile design, the porcelain material has superior characteristics to resist DC ageing, and pins with zinc sleeve can prevent DC electrolytic corrosion. The main E&M performance has reached international advanced level.
