| | | Introducing US DuPont Reliatran Technology and Nomex paper based Class-H & C insulation system approved by UL, open ventilated dry-type transformer is obviously safe, reliable, environment-friendly, (fire + blast + dust + moisture + mildew) proof and of excellent surge capacity, small dimension as well as easy maintenance. Besides, overwhelming advantages of especial design, sound structure, brilliant appearance and outstanding performance make it most suitable for such locations with severe fire restriction or frequent voltage fluctuation as high-rise, airport, bus station, wharf, subway,hospital, power plant, smelting plant, plaza, densely populated areas, petrochemical Industry, nuke and so on.
Electronics & Electrical >> Transformers | | | | | 1.The transformer is of hermerical construction ,which isolates the oil form the atmosphere and therefore slows down the aging of the oil.
2.The edges if the oil tank are welded with stainless steel,Haihong's design patent(Patent No.:00322141.5),to reinforce the machanical strength ,rust prevention, magnet prevention and polishede appearance.
3.The tank is equipped with Haihong's patented accessory YWJ oil level gauge ,which is of reasonable design, direct display ,and thoroughly solves the problems such as ooil level and working temperature indication, pressure relife and ooul conservation.(patent No.:0121516159.9) Electronics & Electrical >> Transformers | | | | | 1) 3-dimensional wound core composed of 3 uniform parts is of stable structure, enhanced mechanical strength and great short current withstand ability.
2) It highly utilizes the magnet-inductivity of cold-rolled silicon steel sheet and lowers the no-load current and no-load loss tremendously through annealing. Its no-load current and no-load loss are 80% and 25% lower respectively than that of S11 China National Standard.
3) Core is wound tightly with excellent cold-rolled silicon steel sheets, which shows more advantages in tightness than that of laminated core, ensures the absence of an air gap and decreases 7-10 db of noise after the annealing and painting processes. In addition, the windings enveloping the core effectively reduce magnetostriction, the main source of hum found in standard vertically laminated transformers.
4) The direction of the magnetic flux of the entire core is the same as the rolling direction of the steel. A high flux density and no-scrap processing, Electronics & Electrical >> Transformers | |
