The wind power combined transformer is a specialized power equipment that integrates step-up transformers, high-voltage current limiting fuses, load switches, low-voltage switchgear, and corresponding auxiliary equipment. The YBM (P) 35F/0.69kV high-voltage/low-voltage pre installed substation series products are products designed and developed by our company specifically for wind power generation. They raise the 0.69kV power bed emitted by wind turbines to 35kV and then output electricity upwards through 35kV cable lines. It is an ideal supporting equipment for wind power generation systems. The new prefabricated substation has the advantages of strong completeness, easy installation, short construction period, low operating cost, high structural strength, and strong anti-corrosion performance. It is fully suitable for operating environments such as beaches, grasslands, and deserts with relatively harsh natural conditions, and its performance fully meets the requirements of wind farm use.

YBM(P)35F/0.69kV
The 35kV wind power combined transformer YBM(P)35F/0.69kV is an integrated prefabricated substation solution exclusively engineered for wind power generation systems. This all-in-one equipment integrates a step-up transformer, high-voltage current limiting fuses, load switches, low-voltage switchgear and auxiliary components, designed to convert the 0.69kV output of wind turbines to 35kV for efficient grid transmission via 35kV cable lines. As a specialized wind farm combined transformer, it features a fully closed, temperature-controlled and anticorrosive enclosure, with pre-installed primary and secondary equipment for plug-and-play deployment. Optimized for harsh natural environments including beaches, grasslands and deserts, it delivers high structural strength, low operating costs and seamless compatibility with onshore/offshore wind power infrastructure, making it the ideal supporting equipment for unattended wind farm substations.

Eliminates on-site assembly of separate components, with pre-installed and pre-tested electrical systems that reduce construction time by up to 70% for wind farm projects.
Fully closed, anticorrosive, moisture-proof and rust-proof enclosure ensures reliable operation in extreme wind power environments, with resistance to salt spray, sand and temperature fluctuations.
Compact footprint reduces land use for wind farm substations, with lower upfront investment and operating costs than traditional split-type substation equipment; ideal for small to medium wind power installations (≤5000KVA).
Stable performance and built-in protective components enable 24/7 unattended operation, a critical requirement for remote wind farm locations with limited on-site personnel.
