This series of products use zinc oxide blocks specially designed for use in high temperature oil. The built-in design for transformers offers a better economical solution than external mounting porcelain type surge arresters. This design also provides better protective performance because it connects the arresters directly to the equipment to be protected.
Oil immersed type surge arresters compliant with IEC standards (IEC60099-4)
Incorporating zinc oxide blocks designed for use in high temperature oil
