Station Class Surge Arresters Description: HENGDA supply a wide range of porcelain and polymeric station type surge arresters. These arresters have demonstrated reliable perfo口nance in environments all over the world for over 25 years. These arresters can be used to protect switchgear, transformers, and other equipment from damaging overvoltage. Strong focus on quality at all stages，企om raw material through to finished product, ensure HENGDA ’ s station surge aηesters are ideally suited for protection purpose and in confo口nity with IEC60099-4. Classification: 10k:A,20k:A Voltage Rating: 15 to 500 kV High Current Performance: 1OOk:A Line Discharge Class: 2 ,3,4,5 Insulation Material: Silicone Rubber & Porcelain.

Safe, secure and economic supply of electricity -Hengda surge arresters. Hengda surge arresters are the primary protection against atmospheric and switching over-voltages. They are generally connected in parallel with the equipment to be pro阳ted to divert the surge current. The active elements (ZnO blocks) of Hengda surge arresters are manufactured using a highly non-linear ceramic resistor material, composed primarily of zinc oxide mixed with o也er metal oxides and sintered toge也er.
