China oil immersed electrical transmission and transformation equipment
Product Description:
With the company's unique calculation program, the iron core, coil, body, leading wire, fuel tank and other components for the 10-35kV class power and distribution transformers are optimized in all directions to ensure product performance, excellent process equipment, careful material optimization, efficient manufacturing, making the transformer with low loss, low partial discharge, low noise etc., the product quality is superior, with energy saving and environmental protection, reliable operation and effectively reduce the operating costs.
Product Advantages:
1.Compared with S9,S11series oil immersed electrical transmission and transformation equipment,the annual average no-load loss of S13 is reduced by 30% and the average load loss is reduced by 20%.At the same time,it saves energy obviously.
2.It has the complete symmetry tri-phased iron core magnetic circuit,which greatly reduces the magnetic resistance and no-load loss,and thus,though adopting the traditional materials,which is more high efficient and energy saving,producing smaller noise and with more compact structure.
| The iron core material | Being selected from high-quality high magnet conductive cold-rolled silicon steel sheet, the iron core processing uses German-imported Georg line cutting device, with the full-gradient ladder joint structure, no hole banding, plate-type clamping part structure. |
| Coil Structure | The high and low voltage coil is packed according to the split phase. The design pressure is evenly compressed to ensure the coil axial strength. The inner coil is lined with high-strength phenolic paper tube. The internal and external struts are used on the high and low voltage coil, technically making ensure enough tightening of the coil radial. |
| Leading Wires | Transformer wires use the oxygen-free copper and high-strength insulation material. |
| Oil Tank Manufacturing | Transformer tank adopts bucket type or bell-type. Model "F" is for the side blowing and air-cooled type.The sealing rubber uses "0" type of the overall structure to ensure that no leakage occurs.All the gas collection pipelines on the top cover of the bell jar adopt the slope structure leading to the gas relay.The fuel tank takes shape by compression molding of reinforcing ribs.The cushion blocks for the jack are 4 pieces and are marked with oil paint.The structure layout of transformer is reasonable, beautiful.The inner wall of the fuel tank is coated with epoxy resin paint.The external wall of the tank paints the high-quality silver power coating. |
| The transformer explosion-proof device | The explosion-proof device uses YSF8-type pressure relief valve. |
| Crimping Technology | Transformer wires use the oxygen-free copper and high-strength insulation material. |

Applications
This product is suitable for the core structures in power plants, substations, large-scale industrial and mining and petrochemical enterprises.
Product Features
Good Economic Performance
Based on S9 series, the no-load loss for S11 series oil immersed electrical transmission and transformation equipment decreased averagely 10.3%, no-load current decreased 22.4%.
The Oil Power Transformer electrical equipments adpots new type insulation structure and makes the shot-circuit resistance strong.
Long Service Life
Transformer tank adopts fully sealed structure, fuel tank and tank rim can be connected by bolts or welded firmly, the transformer oil doesn't contact with the air, extending the service life.
High Operational Reliability
Improve the relevant sealing parts for the fuel tank, increase the reliability and advance the technical level to ensure the reliability of the seal.
Small Installation Area
S11-M series of transformer tank uses the corrugated plate radiator. when the oil temperature changes, the corrugated board expands from the heat and contracts from the cold, which can replace the role of the oil conservator, the corrugated plate type fuel tank has beautiful appearance, less occupied area.
