Medium Voltage

Medium-voltage surge arresters

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

ABB 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.

Applications
 Surge arresters for medium-voltage systems
 Protection of equipment from power electronics to high energy capacitors, arc furnace transformers and other
 Surge arresters for special applications in low-voltage systems
 Surge arresters for AC traction systems
 Surge arresters for DC traction systems
 Voltage limiting devices for traction systems
