Professional machinery equipment production of special transformer, stable, price, special voltages can be customized it. Name: SG, SGG series dry Lotus root/isolation transformers and BK control transformer specifications: BK series 100VA-20000VA SG/SGG 1KVA-1000KVA more than for our regular product model, special specification can be made! Products Description: SG/SGG and the BK control series dry type transformer for Division I introduced Taiwan 90 generation advanced technology, designed three-phase entered Exchange voltage 440V, and 420V, and 380V, common three-phase output Exchange voltage 380V, and 220V, and 200V, and 190V, and 110V power of electrical using and design manufacturing, SG transformer to accelerated air cycle, performance stability; used imports material, has efficiency high, power small, run reliable; appearance beautiful environmental, may independent set, Can also be installed in a Cabinet and equipment and other features in the control cabinet, nominal capacity under the prevention of long-term continuous working, and is widely used as power supply for imported equipment necessary. SG-AutoFormer basic differences and SGG-isolation transformer: SG-auto-transformer is a ring-type transformers, common with a primary and secondary winding, which is common to use a neutral line, its variable-pressure than those with both fixed and adjustable. SGG-is a two-winding transformer isolation transformer, primary and secondary are separated, which means that each of the first level has a zero line. Isolation and auto voltage differences they are mainly on the winding, so its advantage relative AutoFormer isolation transformer, making input voltage and output voltage is totally isolated, high safety factor, on grid filtering effectiveness, terminals can be triangular ()/Y.
