Manufacturer Scb Series 30-250kVA Isolation Electrical Power Distribution Three Phase Dry-Type Transformer

Welcome to our homepage to see more content!Product DescriptionBasic Information.This product conforms to the national standard GB10941-2013 (IEC 60076) power transformer and GB/T6451-2015 indoor dry transformer technical parameters and requirements. Epoxy resin cast transformer is a kind of solid insulated encapsulated winding power transformer. Epoxy resin dry type transformer adopts epoxy resin as insulation material, high and low voltage winding adopts copper strip (foil), pouring epoxy resin vacuum curing, forming high-strength FRP body. Insulation grades are F and h. Epoxy resin dry type transformer has the characteristics of good electrical performance, strong lightning impact resistance, strong short-circuit resistance, small size, light weight and so on. The temperature display controller can be installed to display and control the working temperature of the transformer winding to ensure the normal service life of the transformer.Product Details.  Structure characteristics of dry-type isolation transformer:Iron core adopts high quality cold rolled grain oriented silicon steel sheet, iron core silicon steel sheet adopts 45 degree full oblique connection, so that the magnetic flux passes along the direction of joining silicon steel sheet.There are four winding forms, respectively, winding, epoxy resin with quartz sand filling and casting, glass fiber reinforced epoxy resin casting column (i.e., thin insulation structure) and multi-strand glass fiber impregnated epoxy resin winding.The third type of glass fiber reinforced epoxy resin casting is generally used, because it can effectively prevent the casting of resin cracking and improve the reliability of the equipment.  Product Parameters.                                                 10kV SC(10) Epoxy Resin Cast Dry-Type TransformerRated Capacity (KVA)Voltage Combination (kV)Connection SymbolNo-LoadCurrent (%)Impedance Voltage (%)No-Load Loss (W)Load Loss (W)(120)Weight (KG)Sound LevelLPAHigh Voltage (kV)Tapping 10010±5%±2*2.5%0.4Yyn0Dyn111.34.03701580650441251.34301850730451601.15402120890452001.162025201260462501.072027501290463151.088034601480474000.997039801820475000.9116048802340486300.86.0129059502530508000.81520695027805010000.71770812033105112500.72090969036805116000.624501172044805220000.633201445050505325000.5400017160621054                                           20kV SC(B)10 Epoxy Resin Cast Dry-Type TransformerRated Capacity (KVA)Voltage Combination (kV)Connection SymbolNo-loadCurrent (%)Impedance Voltage (%)No-load Loss (W)Load Loss (W)(120)Weight (kg)Sound LevelLPAHigh Voltage (kV)Tapping 10020±5%±2*2.5%0.4Yyn0Dyn111.06.05401990710451600.96702470980462000.973029401380472500.884034201400473150.796040601600484000.6114048202000485000.6133057602500496300.5151068002700518000.51730822030005110000.52040973035805212500.523601148039205216000.527601379048005320000.532001628054005425000.4382019270678055Technical parameters of dry-type transformers1.
