Why choose Hummer ?
1.SCF generator technology
The generator parts adopt SCF( supercritical generator technology )which has won gold award of the 37thworld invention exposition in Brussels Eureka .it makes our generator smaller size ,lighter weight and higher efficiency .
Hummer SCF generator locates in nose cone ,easy to radiate heat and reduce wind resistance.
2. Blades RTM technology
Hummer blades adopt RTM technology, the blades is vacuum pressed and the whole cast, closed molding, makes the whole blades a formation at a time . it will improve the strength, smooth finish and precision of the blades .The lifespan is 20 years.
3. Siemens PLC
Hummer 3KW-50KW wind turbines adopt Siemens PLC control module with touch screen ,which is capacity of quick reaction to wind signal ,if any abnormal situation occur ,the controller will alarm and adjust the running status of the wind turbine automatically to protect the system .
4. Smart client for remote control
Client can see the datas and control the wind generator on the internet
5. wind turbine special cable
conductor of the cable is tinned copper wires ,the inside liner with tinned insulation net and the oversheath can UV-Resistance.The softness is good with excellent torsion., it can resistance to high (80 centigrade) and low(-45 centigrade) temperature ,anti-corrosion ,so that it can work in bad working conditions
6.Triple braking protection
Hummer wind turbine generally adopts the yawing system and the electromagnetic braking system to regulate the rotate of the wind turbine .Besides. customer can order the hydraulic braking system as well as a third protection ,It easy and convenient to shut down the whole system both manually and automatically .
