Product details
Model Number: ZH20KW-A Brand Name: ZONHAN Key Specifications/Special Features: ZONHAN 20KW wind turbines are made of strong cast steel that makes them durable. ZONHAN turbines can withstand harsh environments like strong winds and cold weather. Using high performance NdFeB permanent magnet, the alternator is highly efficient and compact. The unique electro-magnet design makes the bonding force and cut-in speed very low.Key features:The main generator shaft is machined from 40Cr steel and heat treated to make it extremely tough.The main generator shaft is tapered and has a keyway where the blade hub mounts prevents any hub slip.High quality stainless steel bolts throughout the turbine. High quality castellated, stainless steel nut and pin secures the hub to the main shaft.
  • High quality sealed bearings on the main shaft and the yaw bearing.
  • Vacuum pressure impregnated coil windings in the generator.
  • High quality neodymium iron boron material (NdFeB) magnets are used in the generator. These are also galvanized for longevity and are rated over 150 degrees Celsius.
  • Our slip rings use J164 carbon brush which contains 90% copper, unlike most who use only 20% copper.
  • Good blade profile and size allows these wind turbines to run relatively quiet compared to our competition.
