Product Introduction
The Integral Type Transformer for Wind Power Generation is specialized power equipment integrated with the step-up transformer, high-voltage fuse, load switch, low voltage switchgear and relevant auxiliary equipment.
YBM ( P) 35F/0.69kV High/Low Voltage Prefabricated Transformer Substation series products are designed and developed by our company particularly for wind power generation. It boosts the 0.69kV voltage generated by the wind turbines to 35kV and is transmitted to the grid through 35kV cable lines, which makes it an ideal auxiliary equipment for wind power generation systems. Its performances are completely in conformity with standard of GB/T17467 High/Low Voltage Prefabricated Transformer Substation. Developed for purpose of meeting special requirements of wind power generation, the system is a novel prefabricated transformer substation featuring with characteristics like strong nature of complete set, easy installation, short-term construction cycle, low operational expenses, high structural strength and high anti-corrosive properties, etc. It is completely applicable in harsh natural environments like the beach, grassland or desert, etc., with its performances fully satisfying the usage requirements of the wind farms.
