• Product introduction：

Preassembled box substation for wind power is a complete substation that is pre-manufactured and assembled in the factory for wind power booster station, including booster transformer, high-voltage load switch, low-voltage switch and power transformer and other auxiliary equipment. It is configured in a common enclosure and has passed type test. From the form of structure and European box disguised, so it is also called "wind power Europe". Its performance fully comply with GB/T17467-1998 high pressure/low pressure preinstalled type transformer substation, it is aimed at the specialties of the wind power requirements to launch a new booster equipment, because it has a complete set of sex is strong, easy installation, short construction period, low operation cost, high structural strength, strong anticorrosion performance advantages, fully applicable to the natural conditions are harsh beach, grassland, desert and running environment.

The substation consists of high voltage room, transformer room, cable room and low voltage room, arranged in mesh or product shape; The box is provided with adequate natural ventilation and insulation. When the ambient temperature is close to 40℃, start forced ventilation to ensure the normal operation of the booster transformer; The frame of the box is welded with section steel. The inner hinge is used and welded with the section steel to ensure the strength of the box and door and meet the use requirements in the environment with strong wind power in the wind field; After pickling, phosphating and painting, different shell anticorrosion processes are applied to different operation environments of wind power plants, which can prevent salt spray, damp and heat, mold and outdoor weather. The roof is double-layer structure, which can prevent rainwater from entering and heat radiation from increasing indoor temperature. Separate cable room is set to facilitate the connection of customers; The upper and lower broken parts of the load switch are equipped with insulation baffles to ensure the safety of maintenance. "Five prevention" function is complete, easy to operate and maintain.
