Our strategic location offers exceptional convenience in transportation and a remarkable environment. Spanning an impressive 45,000 square meters, our company integrates the production, sales, and R&D of a comprehensive range of power equipment. From 35KV to oil-immersed transformers, dry transformers, and specialized transformers, to grounding transformers, arc suppression coils, reactors, and diverse box-type substations including the American box transformer, we are a powerhouse in professional power equipment manufacturing.
Product Introduction
Introducing our 10kV grade SC(B)10, SC(B)11, SC(B)12, SC(B)13 epoxy resin cast dry-type transformers, crafted to excel as replacements for traditional oil-immersed distribution transformers. Distinguished by exceptional performance, these dry-type transformers are ideal for critical environments such as urban power grids, towering high-rise buildings, bustling business stations, strategic docks, dynamic airports, and subterranean substations.
Characteristics of the Product
Our SC(B)10 series of 20kV and 35kV non-excitation voltage regulation dry transformers are engineered to be low-loss champions.
Conforming meticulously to the national standards GB6450, GB/T10228, and IEC726, these transformers boast remarkable features:
1. Exceptional high performance coupled with low loss, setting a new benchmark for type 9 series replacements.
2. Crafted from superior quality silicon steel sheets, substantially minimizing magnetic flux density. This not only reduces the operational magnetostrictive weight of silicon steel sheets but also effectively diminishes noise.
3. Optimized high-voltage coil structure enhances interlayer voltage and capacitance distribution, significantly bolstering the product's resilience against atmospheric and operational overvoltage, and refines electric field distribution for overall product minimization.
4. Equipped with an advanced temperature control system and air cooling device, our transformers feature automatic fan cooling activation under heavy loads, thereby significantly enhancing overload capacity.

Shell Protection Device
Constructed from durable stainless steel or aluminum alloy, the shell's protection grade reaches IP20 and IP23. The IP20 housing guards against solid foreign objects exceeding 12mm in diameter, ensuring secure transformer protection. The IP23 housing
offers defense against vertical water flow less than 60°, making it ideal for outdoor operations.
Note: Utilizing IP23 housing allows for cooling benefits, reducing small capacity by about 5% and large capacity by approximately 10%.
