Grade-H Insulation Dry-Type Transformer
Features and advantages: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.1) Safe:a) High level of safety, grade-H insulation class, fire-resistant,non-combustion-supporting, self-extinguishing, free from toxic gas,good fire protecting performanceb) Free from partial discharge and fissuration in service. The insulationsystem of the winding is impregnated with solvent less insulationvarnish time and again by VPI vacuum pressure equipment andsolidified through high temperature baking, therefore it is dampproof,antifouling, dustproof, has intense thermal shock bearing ability, and isfree from partial discharge and fissurationc) Small volume and light weight. The transformer adopts Dupont NOMEXpaper as main insulating material and as insulating system of its mostheated point2) Relievable:a) Great surge capacity and excellent short circuit bearing ability due toits new design, new material, new techniques, and good heat radiationeffect. It can run safely under 120% over loading for long timeb) Dupont NOMEX paper based insulation system enables the transformerto maintain excellent electrical performance and mechanical property inits whole service life. NOMEX ® paper is hardly aged, shrinkageresistant and compression resistant, and is of high elastic force, thus itcan ensure that the windings will still keep tight structure and be ableto endure short-circuit impact even after multiyear service.3) Environmentally friendly:a) No environmental pollution during the manufacture, transportation,storage, and the whole service lifeb) The winding can be disassembled and recycledc) No toxic gas releases under 750°C.d) Low noise. The core consists of high permeability cold rollinggrain-oriented silicon-steel sheet laminations. The laminations arearranged in such a way to reduce the noise level and loss factor toa min. by using step-lap cutting and mounting and the 45° cut atwhich the cores are placedSpecifications:1) 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 conditions:1) 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 outdoor7) We can also provide transformers operated in special conditions according to users`requirements
