Leak and Seal Engineering Solutions

TDS repairs transformer oil leaks and circuit breaker leaks involving SF6 gas or oil. Common repair locations include gaskets, bushings, flanges, drain valves, valve stems, drain plugs, lids, compartments, end caps, radiator fins, and manway covers. TDS also develops custom solutions for non-traditional leak locations and can identify the appropriate method through detection and survey work.

Where conditions permit, TDS can perform transformer oil leak repairs without removing the apparatus from service. Low-pressure sealing, cured-in-place gasket methods, clamps, and engineered enclosures can reduce the need for draining oil or dismantling equipment. The appropriate approach depends on the equipment, leak location, operating conditions, and repair requirements identified during evaluation.

Yes. TDS detects and seals SF6 gas leaks in circuit breakers, including leaks around base mounting flanges, end caps, and other gasketed connections. Technicians use specialized methods such as clamps, drill-and-inject procedures, and custom engineered enclosures. Addressing the leak can help utilities control SF6 losses and avoid unnecessary component disassembly.

Low-pressure leak sealing is a repair approach that uses specialized techniques and sealants to replace failed gasket performance without traditional equipment teardown where conditions allow. TDS applies cured-in-place gasket methods to transformer and circuit breaker components, including pipe flanges, bushing flanges, drain valves, radiator fins, and other difficult locations.

TDS offers free equipment and substation surveys. The survey can identify the facility, equipment, leak location, proposed repair method, and itemized repair costs. Representatives use the findings to help maintenance teams understand the scope of work and evaluate whether a targeted repair may be a practical alternative to traditional disassembly or regasketing.

TDS specializes in electrical utility substation equipment, including transformers, SF6 and oil-filled circuit breakers, GIS systems, and related apparatus. Services include leak detection, oil and SF6 sealing, custom enclosure installation, power washing, and component-specific repairs. TDS also supports power generation facilities and other customers responsible for high-voltage equipment maintenance.

Company information states that TDS provides a full four-year leak-seal warranty. Coverage applies to leak-seal repairs as described by the company. The specific scope for a project should be reviewed with TDS before work begins, including the equipment, repair method, identified leak location, and applicable service terms.

TDS lists service availability across the United States, Canada, and internationally. The company provides on-site support through representatives across its service areas. Availability and travel considerations can vary by project, so maintenance teams should share the facility location, equipment type, and leak requirements when requesting a survey or repair review.
