Dry Type Power Transformer

Dry Type Power Transformer Specifications: Rated Capacity: 30 2500kVA;Rated Voltage:10/0.4kVor other voltage combination in accordance to client needs;Phase No:single or three;Rated frequency:50 or 60 Hz;Short circuit impedance:4%,6% or other in accordance to client needs;Vector group:Dyn11,Yyn0 or others;Tapping range:±2×2.5% or other in accordance to client needs;Partial discharge:less than 5PC;Cooling type;AN or AF;Heat-resisting class:F\HFertures Low noise,low power loss,no pollution,eco-friendly Maintenance-free,smart appearance fire-proof,safety;Highly moisture-proof;Better dissipation of heat; Core:The core is manufactured withhigh quality cold rolledgrain-oriented siliconsteel of high magneticconductivity. 45° mitring and 5-steps overlapping structure is adopted for the core design, thus to greatly reduce no-load loss and no-load current.HV winding:HV winding is manufactured with high quality copper wire, reinforced with glass fiber and being casted withepoxy resin at vacuum state with pressure, having the resin fully impregnated into the coils in the most professionalimported equipment. Therefore, product's partial discharge is especially low;LV winding:LV winding (with the rated power equal to or higher than 400kVA) is manufactured with high quality foil conductor, resulting in excellent ampere-turn balance, low transverse magnetic flux leakage and higher anti-shortcircuit capability. By designing reasonable air conduit in the windings to increase the heat-dispersion surface,transformer's temperature rise is effectively controlled and the overload capacity is greatly improved.Executed standards:GB/T10228, GB1094.11, IEC60076-11, DIN42523
