About us
Shandong Zhifeng Transformer Co., Ltd. is located in the North Rainbow Industrial Park, East Second Ring Road, Linqing City, Shandong Province, a famous canal city, with convenient transportation and beautiful environment. The company covers an area of 45,000 square meters, is a collection of 35KV and below oil-immersed transformer, dry transformer, special transformer, grounding transformer, arc suppression coil, reactor, box-type substation, American box transformer, all kinds of box production, sales, research and development in one of the professional power equipment manufacturing enterprises.
Product introduction
10kV grade SC(B)10,SC(B)11,SC(B)12,SC(B)13 epoxy resin cast dry-type transformers,which can be used as replacement products for oil-immersed distribution transformers.The products with excellent performance in dry-type transformers are especially suitable for important places such as urban power grids,high-rise buildings,business stations,docks,airports,underground substations.
Characteristics of the product
The SC(B)10 series 20kV, 35kV non-excitation voltage regulation dry transformer produced by our company is a low loss product.
In line with the national standards GB6450, GB/T10228 and IEC726 requirements, and has the following characteristics:
1. High performance, low loss, for the type 9 series replacement products.
2. The selection of high-quality silicon steel sheet, while greatly reducing the magnetic flux density, reduce the operation of silicon steel sheet magnetostrictive weight, effectively reduce noise c
3. Optimize the high-voltage coil structure, improve the distribution of interlayer voltage and capacitance, greatly improve the impact ability of the product to withstand atmospheric overvoltage and operating overvoltage, and also improve the electric field distribution, so that the product is further reduced.
4. Temperature control system and air cooling device can be configured to automatically start the fan cooling device when the load is too large, effectively improving the overload capacity of the equipment.

Shell protection device
Shell is made of stainless steel or aluminum alloy.Protection grade can reach IP20 and IP23.IP20 housing can prevent solid foreign objects of diameter more than 12mm enter into and protect the transformer safely.IP23 housing
can prevent the vertical drop of less than 60°of flow,suits for outdoor operation.
Note:IP23 housing can make the transformer cool,small capacity is decreased by about 5%,high-capacity is decreased by about 10%,
