  • Two Winding Transformer Low Partial Discharge 22kv 1500 Kva - China

    price: check with company for price

    22kV - 1250kVA Cast Resin Dry Type Transformer, Three Phases, Two Winding, Power Distribution Features Low loss, compact and light weight, low noise level, clamp-proof, anti-fouling, high mechanical strength, flame resisting, strong overload ability and low partial discharge quality, they are application to power transmission and distribution system, hotel, restaurant, commercial building, stadiums, chemical plants, stations, aiports, offshore drilling platforms, especially to heavy load centers and places with special fire protection requirements. Advantages: # # Low loss, low noise, low partial discharge, high reliability. # Strong capability withanti-short circuit, high anti-lightning impulse capability. # HV coil is vacuum casted with epoxy resin with pressure, capabilities for better the cast without pressure. # Simulating analysis being used in the core model, the resonance can be avoided and the noise is reduced. Simulation calculation and analysis of lighting impulse wave are applied to the HV Coils; anti-lighting impulse capability is improved. BOLTS AND NUTS Bolts and studs for electrical wiring connections shall preferably be of brass M6 size. Nuts and pins shall be locked in position with lock-nuts or lock washers. No bolt or stud shall project through its nut by more than 0.5 times diameter or four threads whichever is the less except for terminals and relay stems. Bolts, nuts and washers on outdoor equipment shall be of non-corroding material, where they are in contact with non-ferrous parts in conductor clamps and fittings and elsewhere if specially required. Suitable special spanners shall be provided for bolts and nuts which are not properly accessible by means of an ordinary spanner. CLEANING AND PAINTING All coatings and protective which are required to withstand service fluids such as pipe, tank, pump, valve, water box and similar linings shall be applied in the works prior to shipping. Washing of any surface prior to the application and/or over coating of paint shall only be carried out with demineralised water or suitable approved solvent solutions. - - - - No. | Items | Unit | | I Basic Information | | | 1 | Rated Voltage ratio | kV | 22kV / 0.433 kV | 1.01 | Rated Capacity | kVA | 1250 | 1.02 | Applicable Standards | | IEC 60076 | 1.03 | Manufacturer | | Pearl Electric | 1.04 | Country of Origin | | China | II Electric Performance | | | 2.01 | Rated Power | kVA | 1500 | 2.02 | HV | kV | 22 | 2.03 | LV | kV | 0.433 | 2.04 | Frequency | Hz | 50 | 2.05 | Number of phase | | Three | 2.06 | Insullation Class | | Class H | 2.07 | Temperature Rise (@40 ambient temperature) | K | 125K | 2.08 | Cooling Method | | AN | 2.09 | Tapping Ranging | | 2*2.5% | 2.1 | Vector Group | | Dyn11 | 2.11 | Noise level | dB | 55 | 2.12 | Impedance | % | 6 | 2.13 | No-load loss | W | 2790 | 2.14 | Load Loss (@120) | W | 13870 | 2.15 | Local Partial discharge | pC | <10PC | 2.16 | Impulse Withstand Voltage (HV/LV) | kV | 75/0 | 2.17 | Power Frequency Withstand Voltage (HV/LV) | kV | 28/3 | 2.18 | Rated Duration of Short Circuit | s | 2 | - - - - 2 Applied Standard GB/T10228, GB1094.11, IEC60076-11, DIN42523
