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

  • Insulating joint protection on city gas and transmission networks
  • AC interference mitigation on pipelines parallel to power lines

  • Passive alternative where a solid state decoupler is not preferred

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.
