Solid State Decouplers

AC grounding and DC blocking in a single solid state unit

Solid state decouplers provide a continuous low impedance path for AC fault current and lightning surge while blocking the DC that the cathodic protection system depends on. With no moving parts and no electrolyte, they need no maintenance and their performance does not drift in service.

Specifications shown are indicative. Final ratings, sizes and materials are confirmed against your technical specification and the CP design calculation at enquiry stage.

Typical Applications

  • AC interference mitigation on pipelines parallel to power lines
  • Monolithic insulating joint protection where fault duty is high
  • Bonding between protected and unprotected structures
  • Replacement of electrolyte filled polarisation cells

Supply only, or supply with installation?

We quote for both. Installation by the same team that supplied the material keeps responsibility with a single agency.
