Basic Info

Model No.:  ZGS-Z. G-/11

Product Description

Model NO.: ZGS-Z. G-/11 Phase: Three Cooling Method: Oil-immersed Type Transformer Certification: ISO9001-2000, ISO9001, CCC Frequency Characteristics: Power Frequency Brand: TIANAN Voltage rating: 11kV Specification: 1250kVA HS Code: 8504340000 Application: Power Coil: Core-type Transformer Winding Type: Two-winding Transformer Usage: Combined Transformer Shape of Coil: OD Installation: Free-standing Trademark: Tianan Electric Origin: China Summarize
ZGS-Z.G-/11 series wind power combined transformer is a special power equipment integrating step-up transformer, HV current limited fuse, Load Switch, LV switch and related auxiliary Equipments. It transforms the 0.69kV voltage produced by PV power motor into 11kV,and output the electricity through 35KV cable circuit, which is the ideal equipment in wind power complete set equipment.
