QOH*1 Solid State Decoupler
1 Product uses
Decoupler is a AC Interference protection product, which sets Embedded-type line flowing and surge protector in one.
It is mainly used in long-distance buried pipeline engineering. As following situations: high-tension transmission line tower and communication tower and their ground system which near the pipeline; public passage between high-tension transmission line and pipeline; cross of pipeline and transmission line or Electrified railway-parallel pipe; the installation of the decoupler can reduce the influence of DC, AC & stray current or thunder flow on the buried pipelines, also strengthen stability of pipeline cathodic protection potential.
