9-12kv Polymer Surge Arrester, Lightning Arrester

9-12kv Polymer Surge Arrester, Lightning Arrester

Description
 
The metal oxide surge arrester (MOA) is the most advanced over-voltage protector in the world. The metal oxide varistors(MOV),  as the core organ, made under japanese technology license. It have good response to steep front surge, excellent volt-ampere characteristics and high discharge capability, which provides a very consistent protection merit at steep front surge,lighting surge anf switching surge, and enhances protective capability.
