Products
Wind power combined transformer is a set of step-up transformer, high-voltage current-limiting fuse, load switch, low-voltage switchgear and corresponding auxiliary equipment in one of the special power equipment.
YBM(P)35F/0.69KV high-voltage/low-voltage pre-assembled substation series products are specially designed and developed for wind power generation by our company, which is to raise the voltage of 0.69KV issued by the wind turbine to 35KV, and then output the electricity upward through the 35kV cable line. It is the ideal supporting equipment for wind power generation system. Its performance is in full compliance with GB/T17467 “High Voltage/Low Voltage Pre-assembled Substation”, which is a new type of pre-assembled substation developed for the special requirements of wind power generation, with the advantages of strong set, easy to install, short construction period, low operating costs, high structural strength, strong corrosion resistance, etc., and it is fully suitable for the operating environment of beach, grassland, desert, etc. where the natural conditions are relatively harsh, and the performance The performance of the substation fully meets the requirements of wind farms.

Product structure and features
1, wind farms are generally built in the mudflats, shallow sea, grasslands, deserts and other sparsely populated places with poor natural conditions, according to the use of different environments using different anticorrosion process treatment, to ensure that the service life of the pre-assembled substation.
2, the overall layout of the box variable for the “Pin” type, the advantages are as follows: compact structure, reasonable, small size; the main components of the connection between the convenient, greatly reducing the amount of copper rows, in and out of the cable wiring space and maintenance space is larger, convenient for assembly, maintenance. Box structure, all metal structural components using sandblasted hot-dip galvanizing, painting treatment, can ensure that the equipment in the humid, heavy salt spray environment using its strong resistance to rust and corrosion, all the door panels and wall newspaper, there is no interlayer, the middle is filled with polyurethane vinegar and silicate. Composite thermal insulation material, it has excellent thermal insulation and heat preservation performance, to ensure that the equipment in the cold environment safe and quickly into operation.
