Polymeric Lightning Arrester

Polymeric Lightning Arrester for AC Power Systems:

Goto’s polymeric lightning arresters provide reliable surge protection across low to high voltage networks. Made with zinc oxide cores and silicone rubber housings, they ensure excellent electrical insulation, UV resistance, and long-term durability.

Available types include:

  • LV Lightning Arrester – for residential or low-voltage grids

  • Distribution Arrester – used in 10–35kV networks

  • Station Arrester – ideal for substations and HV switchgear

  • Capacitance & Motor Arresters – designed for capacitors and electric motors

All models comply with IEC 60099-4 standards and support OEM customisation.
