Protect your insulating flanges against damage caused by surge voltages
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 the smooth operation of the pipeline.
A long service life is vital for the cost-effective operation of pipelines. Active corrosion protection systems are used to protect against rust. When used in regular operation, these require the metal pipes to be insulated against ground potential.
In order to protect the pipe insulation and the insulating flanges against damage caused by surge voltages, isolating spark gaps are used. In the event of a surge voltage, the isolating spark gap becomes low resistant and discharges the voltage. Lightning protection equipotential bonding is thus ensured. Thanks to the highest possible lightning current carrying capacity class H (in accordance with IEC 52561-3), even large lightning currents are safely discharged to ground via a defined path.
Since very high currents are discharged via the material in the event of a lightning strike, the accessories must also be able to reliably cope with these loads.
All accessories for connecting the FLT-ISG… isolating spark gap from Phoenix Contact are therefore designed with the appropriate discharge capacity.
When installing the isolating spark gap, use tested accessories to avoid a spark hazard in potentially explosive areas.
