Product name:
Porcelain housed metal oxide surge arresters
(Belongs to class surge arresters)
Product summary:
This product has large current discharge capacity .2ms rectangular current discharge capacity of metal oxide varistor(diameter 115mm) is 2500A,4/10μs high current impulse withstand capacity is 100ka which passes line discharge class 5.
This porcelain housing is one big shed and one small shed united open sheds,the shed pitch and shed out are reasonable,the specific creepage distance of surge arresters for Ⅲ degree pollution area is 28mm/kv,it improves pollution withstand capacity of product.
Product feature
This product is made of well voltage-ampere characteristic nonlinear metal oxide varistors,its protection performance is excellent.
This product has unique pressure release device ,its arc channel is smooth and pressure release performance is excellent.
High performance double rubber sealing structure is adopted in the product,the constant compression of gasket is less than 15% which ensures good sealing performance.
