STAINLESS STEEL SUBSTATION TRANSFORMER
Stainless Steel Substation Transformers with 316 stainless steel tank & enclosure for coastal, mining, wastewater, and chemical sites. CSA-ready; cULus/SPE-1000 options. Built for harsh Canadian climates (down to −40 °C with winter kits).
Trusted Stainless Steel Substation Transformers manufacturer & dealer
SkyPower designs and supplies stainless steel liquid-filled substation transformers across Canada. Stainless construction mitigates corrosion from salt-spray, chemicals, high humidity, and freeze-thaw cycles—ideal for utilities, mining, and outdoor industrial applications.
Each unit is engineered to meet CSA C88.16 and UL/IEEE requirements with materials and coatings specified for extended service life.
Remanufactured & new units to fit your project
We supply both remanufactured and new stainless steel substation transformers for replacements, upgrades, and new builds. Every reman unit is inspected, reconditioned, and tested to perform as reliably as new while offering strong value and reduced lead time.
Built with 316 stainless steel tanks and enclosures, these units deliver long-term durability in coastal, high-salinity, and chemically aggressive environments.
Custom ratings, terminations, and accessories are available on request.
