Grade-H Insulation Dry-Type Transformer with Fan
Introduction:SG(B)10 series non-encapsulated dry-type transformers introduce the US Dupont Reliatran technology and adopt Dupont NOMEX ® paper based insulation system, which is safe and reliable, environmentally friendly, energy saving, fireproof and blastproof, insensitive to humidity dust and pollution, and of great surge capacity, small dimension and easy maintenance.Features:1) Safe:a) High Level of safety, Grade-H insulation class, fire-resistant, non-combustion-supporting, self-extinguishing, free from toxic gas, good fire protectingperformance.b) Free from partial discharge and fissuration in service. The insulation system ofthe winding is impregnated with solventless insulation varnish time and againby VPI vacuum pressure equipment and solidified through high temperaturebaking, therefore it is dampproof, antifouling, dustproof, has intense thermalshock bearing ability, and is free from partial discharge and fissuration.c) Small volume and light weight. The transformer adopts Dupont NOMEX ® paperas main insulating material and as insulating system of its most heated point.2) Reliable:a) Great surge capacity and excellent short circuit bearing ability due to its newdesign, new material, new technics, and good heat radiation effect. It can runsafely under 120% over loading for long time.b) Dupont NOMEX ® paper based insulation system enables the transformer tomaintain excellent electrical performance and mechanical property in its wholeservice life. NOMEX ® paper is hardly aged, shrinkage resistant and compressionresistant, and is of high elastic force, thus it can ensure that the windings will stillkeep tight structure and be able to endure short-circuit impact even aftermultiyear service.3) Environmentally Friendly:a) No environmental pollution during the manufacture, transportation, storage, andthe whole service life.b) The winding can be disassembled and recycled.c) No toxic gas releases under 750°Cd) Low noise. The core consists of high permeability cold rolling grain-orientedsilicon-steel sheet laminations. The laminations are arranged in such a way toreduce the noise level and loss factor to a minimum by using step-lap cutting andmounting and the 45°cut at which the cores are placed.Specification1) Standard: GB/T10228; GB6450; IEC7262) Capacity range: 30 - 2,500kVA3) Frequency: 50Hz4) Phase: 3-phase5) Tap changing method: off circuit or on load6) Tapping range: ±4 x 2.5% (9 positions)7) Connection symbol: Yyn0 or Dyn118) Impedance voltage: 4% or 6%9) Insulation level: LI75AC35/AC510) Protective enclosure: with or withoutNORMAL SERVICE CONDITIONS1) Altitude: ≤1, 000m2) Highest ambient temperature: +40°C3) Highest annual average temperature: +20°C4) Highest daily average temperature: +30°C5) Lowest temperature: -30°C for outdoor type; -5°C for indoor type6) Indoor and outdoorWe can also provide transformers operated in special conditions according to users` requirements.
