MAINTAIN EFFICIENT POWER INFRASTRUCTURE OPERATION WITH SPECIALIZED LEAK REPAIRS


Power system leak sealing repair involves the application of specialized techniques and materials to effectively seal leaks in power systems. These leaks can occur in various components, such as transformers, cables, switchgear, and other electrical equipment. The primary goal of power system leak sealing repair is to prevent the escape of insulating fluids, gases, or other mediums, which can compromise the system’s performance, safety, and reliability.

Conventional power equipment leak-sealing repairs require equipment to be drained of oil and taken off-line.  Colt specializes in providing safe and innovative approaches to on-line leak sealing and repair while keeping systems pressurized and energized – when safe distances are maintained. Our goal is to eliminate any downtime and to keep critical electric equipment running.

DRILL & TAP


Over time, flapper valves and flanges can deteriorate and cause a leak. We utilize a drill and tap procedure to effectively seal leaks on pressurized equipment. Colt technicians utilize a special dielectric, Dissolved Gas in Oil (DGA) Sealant that is nonconductive. Both uncured and cured it creates no noticeable change in condition of the transformer insulating oil. Because it is not a silicone it will not foam, but it is pliable and expands while curing.

CLAMPS & ENCLOSURES


Colt’s patented interlocking pressure seal enclosures for power systems are stocked nationwide, enabling Colt to quickly build custom clamps with stock inventory for speedy repair. Our off-the-shelf inventory includes:

  • Flange clamps
  • Straight-pipe enclosures
  • 90° elbow-pipe enclosures
  • Strongbacks
  • Connectors
  • Injection valves
  • Wide range of sealants

WEIR REPAIRS


Weir repairs offer a solution for extending the life of corroded or weakened fins and associated structures. Colt designs, fabricates, and installs Weirs, utilizing urethane and other sealants to facilitate the repair.

SF6 GAS LEAK MITIGATION


Leaking SF6 assets in power systems present challenges to carbon neutrality. Colt helps seal these leaks on-line utilizing wire wraps, drill and tap or clamps depending upon the best method to repair the specific leaking asset. On breakers, we typically utilize a clamp. Our team is here to help mitigate SF6 leaks quicky to minimize environmental impact and keep key power systems operational.
