открытый тип высокого напряжения силового трансформатора

power transformer: 30-2500KVA low price, high quality, 100%capacity and 100% full load with an aging more than 20 years CE ISO TECHNICALPARAMETERS Rated Power: 30 2500kVARated HV: 6(6.3, 10, 10.5,11,33,22,35,36)kVRated LV: 0.4kVPhase No. : single or three;Rated frequency: 50 or 60 HZ;Vector group: Dyn11, Yyn0 or others;Short circuit impedance: 4%, 6% or others in accordance to client needs;Tapping voltage regulation type: off-load or on-load;Tapping range: +2*2.5% or others in accordance to client needs;Cooling type: AN or AF Dominant feature: (1) Low loss, low noise and high reliability. (2) Excellent dynamic thermal stability and 100% over-load capacity. (3) Simulation analysis was carried out for the core mould design, thus to greatly reduce noise level. Simulated lightning impulse wave process was carried out for HV winding mould design, thus to greatly improve product's anti-lightning impulse capability. (4) High mechanic strength, great anti-short circuit capability, excellent anti-lightning impulse capability and high reliability. All these performance indexes rank first in the industry in China. (5) Excellent overload capability, capable of continuously working under 110% rated load. (6) Low loss, energy-saving, economic and maintenance free. (7) Nice appearance, small size, less installation space occupation and low engineering cost. (8) Each performance index and technical specification excels that specified in China GB, international IEC and industrial standards. (9) Hermetically sealed corrugated tank structure is adopted, thus to effectively prevent air corrosion to the oil and prolong service lifetime of the transformer.
