High Voltage Equipment Substation Metal Oxide Lightning Arrest, HV Surge Arresters
Polymeric Surge Arrester for 60~444KV A.C system.
Main features: It adopts double sealing structure, the core encapsulates by molded silicone rubber which completely solves the sealing problem of porcelain housed products.
It has a two-way pressure release structure.
Its core component ZnO varistor has good pressure ratio, consistency, large flow capacity and high reliability.
E creepage distance of porcelain housed products is wide which is suitable for IV level heavy pollution areas.
Similar to porcelain housed arresters they use a hollow insulator as housing. This so called composite insulator is made of a fibreglass reinforced plastic tube, with silicone rubber sheds directly moulded onto it. Composite insulators do have a very high mechanical stability.
