11/0.4kv 33/0.4kv 630kVA Oil Immersed Power Distribution Transformer

The iron core of S9-M series low loss energy-saving transformer produced by our company adopts laminated structure. This product is based on fully absorbing the advanced technology and process of domestic oil immersed transformer, combined with the technical level of our company, putting the reliability of the product in the first place, at the same time, the no-load loss and no-load current of the product are greatly reduced.  Features1. The coil adopts a low axial short-circuit force structure. When the transformer is short-circuited, it can greatly reduce the axial short-circuit force and greatly improve the ability of withstanding short-circuit.2. All the bolts and nuts on the cover surface are made of 304 stainless steel, which enhances the rust prevention ability of the transformer.3. Each sealing rubber ring adopts the best rubber material in China, which greatly prolongs the service life of the sealing rubber ring.4. The transformer body adopts a high-reliability support structure to ensure reliable compression of the upper and lower parts of the coil. The entire body structure improves the ability of withstanding short-circuited.5. This not only reduces the no-load loss of the transformer, but also ensures that the core flux is not saturated when the transformer is operating under voltage, so that the third harmonic of the transformer is small.Product ParametersRated capacity(kVA)High voltage(kV)High voltage tapping range(%)Low voltage(kV)Vector Group symbolNo-load Loss(kW)On-load Loss(kW) Short-circuit resistance(%)No-load Current(%)Model93066.31010.511 ±2 × 2.5or±50.4Dyn11orYyn00.130.604.0 2.1500.170.872.0630.201.041.9800.251.25181000.291.51.61250.341.81.51600.42.21.42000.482.61.32500.563.051.23150.673.651.14000.804.31.05000.965.151.06301.26.24.50.98001.47.50.810001.710.30.712501.95120.616002.4014.50.62000318.350.6Company intraduction Nanyang Xinte Electric Co., Ltd. was established in 2004.
