4.Uses the high-pressured undercurrent to replace the low pressure big electric current electric transmission,reducesthe line loss,reduces the / ine movement cost.
5.The 35kV,20kV power source enters directly uses electricity the center,enhances the power supply effectively the reliability.
Product characteristics
1. High safety: SG10 transformer is non-flammable resin, non-combustion during use, flame retardant, will not explode and release toxic gases, will not cause harm to the environment, other equipment and human body, and is not sensitive to humidity, dust and pollution; Operation without partial discharge and never "crack" possibility.
2. High reliability: NOMEX insulation materials are used for high and low voltage coils, and H-class solvent-free impregnation paint is repeatedly impregnated by VPI vacuum pressure equipment, and high temperature curing is repeated. The product is grade H (180 ° C), and the main insulation material is grade C (220 ° C), which has strong overload capacity and good short-circuit resistance. In the case of good ventilation, allow 20% overload operation.
3. Energy saving and environmental protection: After the end of product life, steel, iron and other materials are easy to recycle; All NOMEX paper used will not release toxic substances when burned; Other insulating materials can degrade and do not pollute the environment; Low loss of products, energy saving; Low noise and flexible design.
Characteristics of the product

Transformer core
1, the core adopts high permeability and high-quality grain orientation cold rolled silicon steel, using 45° five-step overlap method to reduce no-load loss and no-load current.
2, the core design adopts simulation analysis method, accurate and effective calculation of vibration frequency and amplitude.
3, the iron core and the coil, the iron core and the clamp between the flexible connection. Through these measures, the noise level of the transformer is increased by 10-15dB compared to conventional products.
Application scenario Dry transformer, relying on air convection for cooling, generally used for local lighting, electronic lines. Mechanical equipment and other transformers, in the power system, the general turbine transformer, boiler transformer, ash transformer, dust transformer, desulfurization transformer, etc. are dry transformers, dry transformers are now widely used in power stations, factories, hospitals and other almost all electrical. With the promotion and application of SC(B)9 series with low noise (distribution transformer noise below 2500kVA has been controlled within 50dB) and energy saving (no-load loss reduced by 25%), the performance indicators and manufacturing technology of dry transformers in China have reached the world's advanced level.
