No-loading loss of our products is lower than domestic S11 series products, and noise level is 2-5 db lower; 2.Based on the mature environment of wind field, combined transformer adopts full sealing structure. Sealing design sufficiently considers the environment of strong wind and sand dust. 3.It also takes the specific application environment of wind field into consideration, like salt fog, cold in north, damp and hot in south, and high altitude; 4.It adopts optimized design proposal, satisfying higher electric, magnetic, thermal and mechanical stress requirements submitted by low voltage ride-through capability on wind power transformer, which ensures reliable operation of the product. " Application As key equipment of wind power generation system, wind power generation grid connection voltage-increase combined electric substation has the characteristics of nature of complete set, easy for installation and has strong environment adaptability, which can reliably runs under various severe environments, such as salt fog, cold in north (minimum temperature-45℃ ), damp and hot in south (maximum temperature +45℃ ) and high altitude (≤4000 m), and etc. " Operation Experience "2 years
