Supply Shanghai zuiun phase 380V isolation transformer

Product Description: Applications Power Brand zuiun Model SBK-60KVA Frequency LF Power phase three phase to single-phase core shape EI-type core in the form of dry cooling in the form of core-type form of winding two-winding moisture-proof way, open, cooling air-cooled appearance structure, vertical, voltage ratio 3P380V/2P220V efficiency (η) 95% rated power 60KVA waveform no additional waveform distortion three-phase transformer Overview: SG series three-phase transformer is my company in the light of international similar products, combined with China's national conditions developed on the basis of production of a new generation of energy-efficient dry-type transformers from 300VA to between 1000KVA, in line with IEC439, GB5226 and other international and national standards, windings are born entire column winding method; transformer vacuum impregnation, transformer insulation class F or H level, product performance reached international advanced level. SG series three-phase transformers are widely used in AC 50Hz to 60Hz, voltage 1500V following circuit, widely used in the import key equipment, precision machine tools, machinery and electronic equipment, medical equipment, rectifier, lighting and so on. Winding capacity allocation products using a variety of input and output voltage level, join groups, the number and location of the regulator tap (typically ± 5%), single-phase secondary winding with a rectifier circuit, is required with shell etc., can be carefully designed and manufactured according to user requirements. Canadian Shield to further relieve the internal high-frequency pulse transformer coupling interference and noise, although shielded isolation transformer to a variety of N-G interference (pulse and high-frequency noise) can effectively prevent, but the transformer must be properly grounded properly very strict, otherwise there will be no resistance to common mode interference effect. Scope SG, SBK series three-phase transformer for AC 50 ~ 60Hz, 1500V input voltage does not exceed the circuit, as the various types of machine tools, electrical machinery and equipment and other general control power, local lighting and indicate power, but also as with a small power supply. Technical features and characteristics: 1, wiring Y / yn 2, input voltage: 3P380V Output voltage: 2P220V 3, Efficiency: ≥ 95% 4, waveform distortion: no additional waveform distortion 5, function: input voltage, output voltage, current and other instructions 7, long-term continuous long-term unattended work 8 Insulation resistance: ≥ 50MΩ 9, the electrical strength: Power frequency sinusoidal voltage 2000V lasted one minute without breakdown and flashover 10, overload: two times the rated current maintaining one minute. Create a new midline in an isolation transformer - grounding grid can relieve common mode interference and other midline problems, isolation transformer will convert three-wire four-wire connection △ Yo system, plus further shielding eliminates interference by the internal high-frequency pulse transformer-coupled and noise, although shielded isolation transformer for various NG interference (pulse and high-frequency noise) can effectively prevent, but the transformer must be properly grounded properly, very strict, otherwise there will be no resistance to common mode interference effect. The company can provide customers with design and production of high-quality isolation transformer.
