Cast Resin Transformers
Singapore
With over 45 years of expertise in cast resin technology, the SGB–SMIT Group stands at the forefront of transformer innovation and quality. SGB-SMIT is renowned for its unique multi-layer winding principle — an approach unmatched by any other cast resin transformer manufacturer. This commitment to advanced design and reliable performance makes SGB-SMIT one of the most trusted and successful producers of cast resin transformers worldwide.
SGB Starkstrom supplies cast resin transformers in Singapore for indoor, fire-sensitive, and environmentally critical installations. Our dry-type transformers use epoxy cast resin windings that are inherently self-extinguishing, making them the preferred choice for Singapore’s data centres, hospitals, shopping malls, hotels, and high-rise buildings.
Available from 100 kVA to 20,000 kVA with voltage levels up to 36 kV, our cast resin transformers are rated to climate class C2 and environmental class E2. The solid encapsulated design eliminates the need for liquid insulation, significantly reducing maintenance requirements and fire risk.
All cast resin transformers are manufactured to IEC 60076-11 and EN 50588 standards, with fire behaviour class F1 (self-extinguishing). Optional IP44 enclosures and integrated PT100 temperature monitoring are available for enhanced protection.
Thanks to the multi-layer winding principle, high surge voltages and switching voltages are handled safely.
Cooling ducts provide thermal reserves and allow for overload, ensuring consistent performance under demand.
Thermal reserves due to special primary insulation allow for overload, protecting your investment long-term.
Glass-fibre reinforced plastics ensure safe transport and operation, even in the case of temperature shocks. These special features imply a high degree of safety both regarding operation and security regarding their investment decision.
Our skilled team in Singapore provides reliable support — covering installation, testing & commissioning, maintenance, and troubleshooting to keep your systems running at their best.
A cast resin transformer is a dry-type transformer where the windings are encapsulated in epoxy resin. They are widely used in Singapore’s buildings, data centres, and hospitals because they are fire-safe, moisture-resistant, and require minimal maintenance compared to oil transformers.
Cast resin transformers are ideal for indoor installations in Singapore including data centres, hospitals, shopping malls, hotels, MRT stations, airport facilities, and any location requiring a fire-safe transformer solution.
Cast resin transformers use solid epoxy resin insulation with no liquid involved, making them fire-safe and low-maintenance. Oil transformers use mineral oil or ester fluid, which offer higher efficiency and are preferred for outdoor substations and higher power ratings.
SGB-SMIT cast resin transformers are rated fire behaviour class F1 under IEC 60076-11, meaning they are self-extinguishing and will not sustain combustion — meeting Singapore fire safety requirements for indoor electrical installations.
Yes. SGB Starkstrom can supply cast resin transformers with optional IP enclosures up to IP44, suitable for dusty or outdoor-sheltered environments in Singapore.
