Specialized detection and sealing addresses SF6 gas leaks at circuit breaker flanges, base mounting areas, end caps, and other gasketed connections while helping reduce gas loss.
Cured-in-place gasket repairs provide a cost-effective alternative to traditional teardown and regasketing, with targeted work designed to reduce disassembly and downtime.
TDS designs, fabricates, and installs custom clamps and enclosures for difficult leak locations, using proprietary rubber-based sealant and removable designs where access is needed.
Technicians locate and confirm transformer oil and SF6 gas leaks, documenting equipment, leak locations, repair methods, and itemized repair costs through substation surveys.
Specialized power washing removes oil stains and dirt from transformer and circuit breaker equipment using biodegradable, water-soluble Transformer Cleaner.
Industrial electrical equipment repairs do not always require traditional disassembly or extended outages. TDS uses specialized low-pressure sealing methods for transformers, SF6 and oil circuit breakers, GIS systems, and other substation apparatus. Precise leak confirmation helps technicians repair the affected component while equipment may remain energized and in service when conditions allow, helping utilities and power facilities control oil loss, gas loss, and maintenance disruption.
