Pipelines Cathodic Protection Surge Protector


An Isolating Spark Gap SPD is designed to protect thepipe insulation and the insulating flanges against damage caused by lightningimpulse or surge voltage. They discharge the overvoltage energy in a dangerous,potentially explosive atmosphere without sparking. During the event of surgevoltage an isolating spark gap becomes low resistant and discharges thevoltage. With the help of highest possible lightning current carrying capacityclass in accordance with IEC 52561-3, even large lightning currents safelydischarge to ground via a defined path.


An Isolating Spark Gaps can avoid failures, downtimes,and even leaks on pipelines and protect sensitive insulating flanges against sparkover. The isolating spark gap safely discharges surge voltages and ensures thesmooth operation of the pipeline.
