Pipelines Cathodic Protection Surge Protector

An Isolating Spark Gap SPD is designed to protect the pipe insulation and the insulating flanges against damage caused by lightning impulse or surge voltage. They discharge the overvoltage energy in a dangerous, potentially explosive atmosphere without sparking. During the event of surge voltage an isolating spark gap becomes low resistant and discharges the voltage. With the help of highest possible lightning current carrying capacity class in accordance with IEC 52561-3, even large lightning currents safely discharge 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 spark over. The isolating spark gap safely discharges surge voltages and ensures the smooth operation of the pipeline.
