Shenda Electic Group Co., Ltd
Shenda ( In full: Shenda Electric Group Co.,Ltd.) is one of the leading manufacturers in the power transmission & distribution industry. Founded in 2000 and currently employs about 1,100 employees worldwide. Shenda operates three factories (two in China and one in the United States of America - R. E. Uptegraff Manufacturing Company, LLC of Pennsylvania, U.S.A.). Shenda also owns other ten subsidiaries throughout China. The annual gross sales is USD$250 million in 2015.
Shenda's annual total production capacity is about 18,000,000 KVA, Our main products include oil immersed power transformer(up to 250MVA/ 330kV) , dry type transformer(up to 20MVA/35kV), combined transformer substation, amorphous alloy transformer, rectifier transformer (100MVA/220kV )and especially furnace transformer(180MVA/220kV). Our products' performance measures up to the standards established by International Electric Committee (IEC).
All of Shenda transformers' parts' manufacturing must put quality management system: ISO 9001:2008 Into practice, and only those transformers that have successfully passed all the comprehensive tests will then go into practical application. Additional Shenda Electric's products have obtained Short circuit test report from CESI Italy, Type test report from KEMA Netherlands, V-check certificate from KESCO Korea, etc.
Owing to our good reputation on quality and service, our products have been sold well not only throughout China, but also exported to more than 60 overseas countries and regions
Today Shenda is one of the largest supplier of furnace transformer to the steel industry and the largest supplier of power transformer in Ecuador.
SHENDA has formed its own technology characteristics by absorbing and assimilating advanced technology, the iron adopts the advanced 45o total -oblique connecting seam, upper iron yoke non-folding to reduce the no-load loss; adopt advanced core column tightening device to reduce the noise further; the winding adopt combined lead and transposition lead to reduce the additional loss; calculation accurately the impulse features of electric filed and winding to ensure the excellent electric property and impulse intensity.
