Product Overview
The SCB10 series epoxy resin cast dry-type power transformers serve as high-performance, ultra-reliable core electrical equipment specially developed for 35kV medium and high-voltage power distribution networks. With a wide capacity range spanning 50kVA to 2500kVA, this product line is flexibly engineered to match diverse power distribution demands, perfectly integrating high operational stability, environmental friendliness and low maintenance into one compact, robust solution.
Adopting a mature epoxy resin casting process and oil-free dry-type structure, it fundamentally eliminates the risks of oil leakage, fire hazards and environmental pollution that trouble traditional oil-immersed transformers. Featuring strong resistance to moisture, dust and chemical corrosion, it maintains stable performance even in harsh operating environments and requires almost no daily maintenance, greatly reducing on-site upkeep costs and labor input. These outstanding advantages make it the optimal power distribution solution for modern facilities and projects that prioritize operational safety, eco-friendly performance and maintenance-free operation.

Product Features
Low load loss
Our dry-type transformer windings are made of highly conductive copper, and the structure and layout of the windings are optimized during the design and manufacturing process. This optimization not only reduces the resistance of the windings, reduces magnetic flux leakage losses, but also effectively reduces load losses, thereby significantly improving the operating efficiency of the transformer.
Strong short-circuit resistance
The high-voltage winding of this SCB10 transformer adopts a segmented multi-layer cylindrical structure, and the low-voltage winding adopts a foil structure. This structural design makes the winding ampere-turn distribution more balanced, with less magnetic leakage and high mechanical strength. It can not only effectively withstand the electric force generated by short-circuit current, but also has strong short-circuit resistance.
Advanced production technology
The low-voltage winding of our resin-cast dry-type power transformer is wound with copper foil, and the high-voltage winding is made of copper wire cast and cured with high-quality epoxy resin under vacuum. This process makes the winding form a solid whole with high mechanical strength, strong short-circuit resistance, and excellent moisture and dust resistance.
