S9-M oil-immersed transformer can serve both indoors and outdoors at an ambient temperature up to 40°C. With reasonable structure, they are capable to withstandshort-circuit and overload, and they are free of maintenance and easy to repair.The side section of the core is oval-shape and the laminations joints are 45°miteredat 4-step-lap, which gives a compact space factor and thereby lower no-loadlosses. The whole process is controlled by computer. The upper yoke is freeof stacking. So it can reduce iron loss when assembling and disassembling the yokefrom limbs.Both HV and LV windings are designed in layer and cylindrical structure. Insteadof corrugated pressboard, laminated-wood rods are used to form oil-ducts which areeasier for oil circulation and to speed up dissipating winding heat. That is whyour transformer gets higher overload capacity. The LV winding of 250kVA and aboveis made of imported copper foil. Winding layers` insulation is made up of diamonddotted paper, which is glued with all windings into an entirety after hot drying.This helps to strengthen the winding mechanism ability, which increases strongercapacity to withstand shot-circuit.All wiring are connected in a flexible way, so they would not loose or be brokenduring transportation. The height of an active part is changeable with bolts andrubber under bottom. The active part would not be displaced during transportation,thus the product is reliable. Every active part gets drying in a vacuum space.We use vacuum oil filling technique when covering the transformer in order totake away the moisture.Our products are designed in tank structure of hermetically sealed. Its featuresare anti-aging, free-maintenance, breathing, and low noise.Specifications:Rated voltage: 11, 10.5, 10, 6.3, 6kV (or as customer`s requirements)Rated power: 50 - 100,000kVATapping range: ±5% or ±2 x 2.5% (or as customer requirement)Frequency: 50HzNumber of phases: 3Connection symbol: Yyn0, Dyn11 or othersCooling method: ONANTemperature rise limits: windingTop oil:Conservator typeVoltage class: 6kV, 10kV, 20kV, 35kVPower frequency withstanding voltage: 25kV, 35kV, 55kV, 85kVLightning impulse withstanding voltage: 60kV, 75kV, 125kV, 200kVService condition: altitude conditionsStandards: GB1094 power transformer, GB/T6451 technical data and requirement of three-phase oil immersed power transformer, IEC60076 power transformer and JB/T3837
