Type: Envelop oil-immersed distribution transformer
The 3D volume roll iron core envelop oil-immersed transformer, designed and developed by Jiangxi Hanspower Technology Co.,Ltd.’s(Jiangxi Fengcheng Power 3D electric Co.,Ltd ago), reform created the traditional transformers’ magnetic circuit configuration and whole composition. So as to the products not only have all the advantages of common oil-immersed transformer, but also the 3-phase magnetic circuit symmetry entirely, the 3-phase no-load current balance, no-load loss and no-load current are lower, the volume and weight are less as well as quieter; are more and more warmly welcomed by users. The product is very fit to the rural power grid load characters, can be the substitute for projects for construction and upgrading urban and rural power grids, and other distribution projects.
Function characters:
 Voltage grade: 10-35/0.4KV, capacity: 30-2500KVA;
 With the introduction of 3D volume roll iron-core, the 3-phase magnetic circuit symmetry;
 No-load loss and no-load current are much lower;
 Continuous without seam roll iron-core, little noise;
 Envelop pressure protect the oil box, prevent the oil ageing, save the maintenance cost;
 High burning point of oil if the user require, safer and longer life time.
