SFSZ9-31,500/110 kV Level of Oil-immersed H Transf

SFSZ9-31,500/110kVLevel of Oil-immersedH series Transformer introduced Hitachi large-size transformer design drawings, construction technology and management methods of producing high-quality products.The transformercomplies with national standards GB1094-1996 power transformer and the international electrotechnical commission recommendation IEC76-1993.It has the ability of low loss, low noise, short-circuit withstand, etc. Product Features: 1) Unique structure, core iron yoke by D, 44 ° / 46 ° inclined seams. 2) Winding reasonable design, high-voltage winding pads insulation structure, within the turn-to-turn insulation, on-load changer coil winding with independent coil, medium by double continuous coil, the period of coil adopt independent cylindrical coil, using double screw coil voltage, Ann ratios, improve balance state under short-circuit capacity. 3) Winding among USES the baffle plate, make oil flow direction, enhance cooling effect. 4) Insulation of advanced structure, the distribution of the electric field, improve corona discharge level. 5) Overvoltage insulation level is high. High level of 60KV neutral-point insulation. 6) The cold-pressing technique based on welding technology, craft, coil group sets of advanced processing technique. Applications: It is widely used in the residental district, shopping malls and hotels, large construction site, industrial and mining business, power plant andthe substation. Benefits we can offer you: Our professional engineer will design and manufacture the transformer according to your requirements. CNBK is in spirit of Quality first,Customer first principle of service, we will offer our customer best goods and best service.
