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 a better protective performance as the arresters are connected 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
• Improving protective performance
