Our company’s three‑phase resin‑insulated dry‑type transformers are designed and manufactured with advanced equipment under the guidance of excellent corporate culture, management modes and development technologies of Germany’s AEG Company, having undergone rigorous reliability verification.
The SCB‑series three‑phase resin‑insulated dry‑type power transformers of 10 kV, 20 kV and 35 kV voltage classes have passed all routine, type and special tests, as well as climate C2, environment E2 and fire‑behaviour F1 classification tests conducted by the National Transformer Quality Supervision and Inspection Center.
The SCB‑2500/12.47 power transformer has passed short‑circuit tests at KEMA Laboratory. The SCB‑1600/11 and SCLB‑2000/20 power transformers have obtained KEMA type‑test certification, and the SCLB‑2500/13.8 has passed type tests by KEMA of the Netherlands. The complete set of dry‑type transformer with enclosure and connecting busbars has passed seismic tests carried out by the State Key Laboratory of Disaster Reduction in Civil Engineering, Tongji University. Transformer windings have passed ‑40 °C cold‑storage tests and three‑proof tests at the Test Center of Shanghai Marine Equipment Research Institute.
Our products are exported to the United States and countries across the globe, and are also sold in the domestic market.

Product Features
- An energy‑saving and eco‑friendly product with safety, flame‑retardant performance, low noise and zero pollution, which can be installed at load centers. It is a reliable product complying with climate C2, environment E2 and fire‑behaviour F1 classes.
- High‑voltage and low‑voltage windings adopt full‑foil construction, featuring strong resistance to lightning impulse and short‑circuit as well as high operational reliability.
- High‑voltage and low‑voltage windings are of full‑epoxy‑resin vacuum‑cast construction with low partial discharge. Air ducts (patented technology) can be arranged for excellent moisture‑proof and heat‑dissipation performance. The transformer can run normally under 100 % relative humidity and at ‑25 °C. Its capacity can be increased by 25‑40 % under forced‑air cooling.
- Easy for installation and maintenance, with low operating losses and low comprehensive operating costs.
- Equipped with temperature display and control system immune to electric and magnetic interference. A computer interface can be provided to realize remote control and monitoring, guaranteeing safe operation of the transformer.
- It can be fitted with protective enclosure and connecting busbars, suitable for indoor or outdoor application. The indoor modular assembled enclosure is free from the limitation of door‑frame dimensions at site. The connecting busbars can be directly connected to switchgear busbars for broad applicability.

Drawing of Overall Dimensions and Terminals for 10 kV Class Three‑Phase Resin‑Insulated Dry‑Type Power Transformer
Protection degrees of transformer cabinets comply with GB4208 standard.
Indoor‑type: Transformer cabinets are available in protection degrees IP20, IP30, IP21, etc.
Outdoor‑type: Transformer cabinets are available in protection degrees IP23, IP24, IP34, etc.
Features: It prevents human access to hazardous components inside the cabinet and ingress of relevant solid foreign‑objects. It delivers good ventilation and heat dissipation performance. The transformer and cabinet can be transported and installed separately, or transported and hoisted as a complete unit.
Materials: Standard transformer cabinets adopt powder‑coated steel plates, capable of resisting 200‑hour salt‑spray corrosion. Stainless‑steel plates or aluminum‑alloy plates are also optional.
Accessories: A control wiring box is fitted on the door panel. A temperature display controller can also be mounted on the door. For on‑load tap‑changing products, an on‑load tap‑changer controller may be installed on the door panel.
Our company can also supply and install tinned connecting copper busbars inside the cabinet. The cabinet can withstand seismic ground acceleration a₉: 0.6 g in horizontal direction and 0.3 g in vertical direction.
