Transformer Powerwashing and Cleaning

Transformer cleaning should be planned around equipment condition, site safety requirements, and the type of contamination present. TDS uses specialized pressure washing with biodegradable, water-soluble Transformer Cleaner to remove oil stains and dirt from transformer equipment. Cleaning should be coordinated with qualified substation personnel and followed by inspection for leaks or damaged components so visible contamination is not mistaken for the source of an active leak.

Service frequency should follow the equipment manufacturer’s guidance, facility maintenance program, operating conditions, and inspection findings. Cleaning may be appropriate when oil stains, dirt, or environmental contamination affect inspection or housekeeping. Leak detection and repair should be considered whenever oil or SF6 loss is observed. TDS can support a substation survey to document equipment, leak locations, repair methods, and estimated repair costs.

Cleaning and repair requirements depend on the equipment, site conditions, work plan, and applicable safety procedures. TDS provides on-site services for energized and in-service apparatus where conditions permit, and many low-pressure leak repairs are designed to avoid traditional disassembly. The customer’s qualified site personnel and TDS representatives should determine whether cleaning or repair can proceed safely without an outage.

TDS uses Transformer Cleaner, a biodegradable, water-soluble product intended for removing oil stains and dirt from transformer equipment. It is available in full-strength or diluted ratios according to the cleaning requirement. Product use should be managed by trained personnel in accordance with site procedures, environmental controls, and the equipment’s operating context.

TDS addresses common leaks involving valve gaskets, bushings, drain plugs, lids, valve stems, compartments, flange joints, radiator fins, manway covers, and related connections. Technicians first identify the leak location, then select a targeted low-pressure sealing method, cured-in-place gasket repair, clamp, or engineered enclosure. The appropriate approach depends on the component and site conditions.

Yes. TDS provides detection and sealing services for SF6 gas-insulated circuit breakers, including leaks at base mounting flanges and end caps. Technicians may use specialized clamps, drill-and-inject methods, or engineered enclosures. SF6 is regulated by the EPA, so leak work should be coordinated with the customer’s environmental and compliance procedures.

Powerwashing requirements vary with equipment condition, contamination, access, and the site work plan. TDS’s related low-pressure leak-sealing methods are intended to reduce traditional disassembly and may allow repairs while apparatus remains energized and in service when conditions permit. A substation survey helps identify the equipment, leak location, repair method, and expected work scope before service begins.

TDS lists service availability across the United States, Canada, and internationally. The company provides on-site substation services and offers free substation surveys through its representatives. Project logistics, travel, and site requirements are evaluated separately, so customers should provide equipment details and facility location when requesting an assessment.
