2000W wind turbine components
2000W Wind Turbine Generator

Product Description:

H3.8-2000W mainly includes generators, nose cones and protective covers, the world's most advanced Hummer generators, and won 4 independent intellectual property rights. It is made of high-efficiency magnetic materials, special copper alloys, high-strength stainless steels and aerospace aluminum alloys. It is extremely light and small but with high generating efficiency.

Yaw shaft made of fine steel parts, it is used to connect generator, blades, tail pole, tail wing with tower together. With the slip ring, it can rotate at 360°.

The nose cone is made of reinforced aluminum alloy and is located in front of the blade to reduce windage. The generator is enclosed in the nose cone, which is favorable for heat dispersion.

Product Characteristic:

The protective cover is made of reinforced aluminum alloy between the blade and the nose cone to further reduce windage and protect the generator. The off-grid inverter adopting SPWM technology has a filter with high conversion efficiency, stable output frequency and stable voltage, and filters out noise. It is used in off-grid systems and supplies power to electrical loads.

It is equipped with two world-famous SKF bearings, which are of good quality and long history, ensuring that the system is in a reliable, safe and stable operating state.

A flange made of fine steel for fixing the blade. Blades made of glass reinforced plastic, they receive wind energy and convert it into mechanical energy. Every 3 blades compose one set and pass strict balance test before delivery.
