Type: Non-envelop dry-type transformer
The 3D volume roll iron core non-envelop dry-type 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 H grade plane non-envelop dry-type 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 warmly welcomed by more and more users. The products are widely applied in high buildings, shopping centers, airdromes, sub-way, stations, docks, petroleum, chemistry industry, nuclear power stations, nuclear nukes, residential areas, light rail transit, power plants and so on, wherever should be fire proof, burst proof.
SGB11(10)-RL series 3D volume D style roll iron-core H grade non-envelop have many advantages as below:
 Initiate “3D Volume D style roll iron-core dry-type transformer”, new & unique configuration, advanced capability, multinomial patents;
 Iron-core convoluted without seam one-off, core pillar is absolutely rounded, the value section fill factor of iron-core is more than 99%, optimal design params goes well.
 3-phase magnetic circuit shortest, reluctance loss least, no-load loss and no-load current is lower than international standard 40% and 80% respectively, benefit remarkably from energy-saving, loss-lowing, power-saving.
 3-phase magnetic circuit are equal length and symmetry, 3-phase voltage balance, without wave distortion, very little noise(lower than international standard 10db);
 With the introduction of U.S. Dupont NOMEX insulating materials and Germany MORA winding technology for the coil insulating configuration, upgrade the products insulation and heat-resistance to H grade, decease 80% of fuel;
 Fire proof and damp proof, flame proof and fire resistant, don’t need strong wind to cool even work long time in 180℃ setting, strong load capability, environmental, the materials can be degradated and recycled completely after product life cycle;
 Special iron-core and coil configuration as well as the VPI technics, lower the products composition, stabilize the power capability, have very good performance of cooling and endurance of heat impact;
 Continuous and compact roll iron-core, copper foil coil and ingenious steel clip assembly joins to a whole, the short circuit resistance capability is very strong;
 Unique 3D volume configuration, so it has small cubage, little weight, fix space saved, and effective, energy saved, low loss, long life cycle and low operation cost, high value with competitive price, and the social economy benefit is remarkable.
