11kV SCB9,SCB10 Series Resin Insulation Dry Type Transformer1. Dtandards: GB1094-1996; JB/T10088-2004; GB/T10228-2008; EQV IEC726 2. Voltage Grade: 6, 11kV 3. Voltage Regukation Mode: Off circuit tap changing; On load tap changing 4. tapping Range: ±5%, ±2×2.5%, ±4×2.5% or others 5. Frequency: 50Hz; 60Hz 6. Phase: Three phase 7. Connection Sign: Yyn0, Dyn11 or others 8. Short Circuit Impedance: Standard impedance 9. Max. Temperature: 120K 10. Cooling Method: AN or AF 11. Insulation Class: Grade F Features: High voltage coils are wrapped with Polyester enameled wires, filled with glass fiber, and then resin under vacuum condition. It becomes solid under high temperature. It equipped with high mechanical intensity, low discharge partly; Low voltage coils are wrapped with a whole piece of copper foil, with strong anti-shortcut capacity. The core is made of silicon steel. By reasonable choosing magnetic density, decrease the empty loading loss effectively Fire protection, anti-explosion, and no pollution Coil is free from humidity, low noise and well characteristic of heating dispersion Low loss, energy saving, free from maintenance, small size, light, and easy for installation
