WSPGDT

The WSPGDT is a high power isolating Gas Discharge Tube (GDT), intended for equipotential bonding of structures or components that cannot be directly bonded to earth during normal operation (for example pipelines with cathodic protection systems). In the event of a potential difference developing between the parts connected with a WSPGDT, the GDT breaks over and connects the parts for the duration of the overvoltage (Typical resistance at initial breakover is 0.001 to 0.002Ω). After the overvoltage has been cleared, the device returns to its high resistance state.

The device is IP66 rated, allowing for installation both indoors and outdoors, as well as in damp or subterranean areas.

Features and Benefits:

  • Simple to install.
  • Minimum life of 100,000 hours
  • Lightweight item weighing 320g
