High-voltage surge arresters 17 umbrella

Product Description


The metal oxide surge arrester(MOA)is the most advanced over-voltage protector in the word.The metal oxide varistors(MOV),as the core organ, made under japanese technology 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  and switching surge,and enhances protective capability.
The polymeric house,as a new generation of insulation,is characterized by small size,light weight,high strength,resistant to heavy pollution and free from cleaning maintenance.
The product has been confirms by the chines national center for quality supervision and test of insulators and surge arresters.
The technical performance of the product conforms to IEC60099-4 standard technical requirements.
