Features:
New type of S11-M series three phased oil-immersed transformer uses new structures of insulation and anti-shortcut etc. Which approach advanced international standards Comparing to S7 series, the no load loss decreases 10.25% in average, no load current decreases 37.9%, load loss decreases 22.4% in average, it is the renew products for saving energy
Low losses, energy saving
Core is in round form, multi-stage, and entire tilted three stages seaming and lapping structure
High and low voltage coils are winding with oxygen free copper coil. All high voltage coils are made with several layered bucket structure
Reasonable structure

Zhejiang Guangfa Transformer Co., Ltd. is located in the centre Industrial Park in Yueqing, Zhejiang, China, established in 2003. We work with research institutes, well-known transformer joint enterprises, make extensive technical cooperation, and complement with each other, sharing resources. With the advanced management philosophy, strong technical strength, advanced manufacturing technology and its advantages in resources, we has gradually become one of a number of supporting in branch, and seted development, design, production and sales in one system we worked as one of the sentinel transformer production enterprises and has passed the ISO9001 international quality system certification.
The company has a complete product development system developed by our lead, transformers electromagnetic computing optimized system (BYQ-CAD) and graphics packages for each product is our excellent performance guarantee. At the same time: complete factory production equipment, advanced manufacturing technology is our product mix reasonable, low noise, the small-protection. A complete product quality testing equipment and tools and comprehensive quality assurance system throughout the plant from raw materials into manufactured products to test the entire process, is the credibility of our business lives. The company strengthens the modern enterprise system management, computer software OA system enabled us to design, production, logistics, user information to make accurate and efficient response.
The company mainly produces 35 KV level and below the S9, SZ9, S9-M, S10, S (R) 11, KS9 series of three-phase oil-immersed power transformers, SC9, SCB9, SG (H) B10 series of dry-type power transformer, CKS dry - Core reactor, CKK dry hollow reactor, KBSG series of mine flameproof dry-type transformers, KBSGZY series of mine flameproof mobile transformer station, ZHSKS series rectifier transformers, in particular, HC, HK, HL series of shell-and-electric furnace Transformer, widely used in steel-making, calcium carbide, ferromanganese and ferrosilicon, industrial silicon, phosphorus, graphite, and other industries, praised by the majority of users. At present, domestic manufacturers can only minimal professional production.
Our aim is: "leading technology, quality, integrity-based, the pursuit of excellence."
