The isolating spark gaps is one of the imperative device in surge protection as it serve the cathode protection in oil and gas pipeline. The Cathodic surge protection devices protect the equipment from corrosion. This surge protection device works against the lightning and switching surges. The relative humid isolating spark gaps can bear more than 95%. This surge protector stands for equipotential bonding thus grant the conductive connection in gas pipeline components.

It shall be manufactured and tested as per IEC 62561-3.
