Medium-voltage surge arresters

Surge arresters are used for protection of electrical equipment from all kind of overvoltages caused by lightening or switching operations. Hitachi ABB Power Grids has more than 100 years of experience in designing and manufacturing surge arresters and protection devices.

Hitachi ABB Power Grids surge arresters are made of metal-oxide (MO) resistors without spark gaps directly molded in silicone housing, in grey color, and designed and tested according to IEC 60099-4 and IEC 62848-1.
