Model Number: ZH2KW-F Brand Name: ZONHAN Key Specifications/Special Features: Structure and main performance:ZONHAN turbines are made of strong cast steel that makes them durableZONHAN turbines can withstand harsh environments like strong winds and cold weatherUsing high performance NdFeB permanent magnet, the alternator is highly efficient and compactUnique electro-magnet design makes the bonding force and cut-in speed very lowKey features:Main generator shaft is machined from 40Cr steel and heat treated to make it extremely tough

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
