Composite Pipe Repair

Industry: Power Transmission

Solution: Pipe-Type Cables - HPFF

ID: CPR-5-00108

Project summary:

A dielectric fluid leak was found in several small diameter fluid-filled feeders near a substation. The pipe-type cables had a copper outer pipe and very low clearance around each pipe. A typical welded sleeve or clamp could not be used because of the tight clearance. After a temporary leak stop was installed, six layers of high strength carbon fiber was wrapped around the pipes. This six-layer system provided a permanent repair for these copper, pipe-type cables.
