Oil-bath bearings. 20-year design life

Many of the conventional wind turbines are equipped with drip-proof bearings. However these types of bearings usually do not last much more than 2 to 3 years under the natural environment with severe exposure to rain and dust.  These Wind Turbines employ water-proof oil-bath sealed bearings accompanied with a sealing system taken from marine engineering.  Additionally, the triangle blade has a structure similar to durable Truss. Together, it achieves a 20-year design life.

Independent fail-safes ensure safety use in populated areas

Serves well as landmark or messenger

The unique shape and slow gracious rotation of these units draw attention. TRONC streetlight unit would make an landmark, an ad pillar, or a symbol that communicates your message.  We can also customize your unit by adding colors to your specifications.

Starts without power-assist

At normal rotation speeds, this Wind Turbine captures wind with both front and rear blades, which makes it work as a high-torque six-blade turbine. Along with the proprietary non-cogging DC generator, these Wind Turbines start rotating at a wind speed of as low as 1.6m/s without consuming electricity for power-assist activation at a cut-in wind speed. This means that our Wind Turbine does not require a fragile anemometer to detect a cut-in speed. Plus, the three-dimensional rotor captures variable winds, which adds to the overall practical efficiency.
