The necessity of anti-corrosion for wind power equipment

The natural conditions of the wind field where the wind power generation equipment is located are quite harsh, with winds above level 4 all year round, accompanied by the alternating effects of wind, sand, strong sunlight, wind, rain, ice and snow, and cold currents and high temperatures. A wind power station located by the sea is also eroded by salt spray. Therefore, effective anti-corrosion measures must be adopted to protect wind turbines and towers, extend their service life, and reduce frequent maintenance work.
Zindn's cold spray zinc series products can provide long-term protection for wind power equipment.
