20kV 级、35kV 级 SC(B)10
干式变压器
Dry type transformer

产品介绍
Product introduction
本系列产品用于将 20kV、35kV 电网电源直接降低为 400V 配电电源或 10kV 输电电源
为用户供电，由于具有显著优点，为越来越多的工程所采用。其主要优点有：
1. 减少占地和多级变电工程建设，具有显著的社会效益。
2. 节省工程投资，提高经济效益。
3. 减少 10kV 输变电环节，使运行维护费用明显降低。
4. 采用高压小电流代替低压大电流输电，减少线路损耗，降低线路运行成本。
5.35kV、20kV 电源直接进入用电中心，有效提高供电的可靠性。

This series product uses in the 20kV, 35kV electrical network power source
reducing is directly the 400V power distribution power source or the 10kV electric
transmission power source is the user power supply, because has the remarkable
merit, uses for more and more many projects. lts main merit includes:
1.The reduced occupying a land area of and multistage changes the electricity
engineering construction, has the remarkable social efficiency.
2.Saves the project investment, enhances the economic efficiency.
3.Simplifies the 10kV power transformer link, causes the movement maintenance
cost to reduce obviously.
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
20kV 级、35kV 级 SC(B)10 the power supply effectively the reliability.

Low pressure can use foil coil
环氧树脂浇注型 Our company produces SC(B)10 the series 20kV level, the 35kV level adjust the
Epoxy resin cast dehydration pressing type transformer without the excitation to be the low loss
product, conforms to national standards GB6450, GB/T10228 and the IEC726
三 相 request,and has following characteristic:
Three-phase
1.The high performance, the low loss, is 9 series update products.
2.Selects the high quality silicon steel plate. simultaneously is large reduces
the magnetic-flux density, reduces in the movement the silicon steel plate
magnetostriction quantity, reduces the noise effectively.
3.The optimization secondary winding structure, improved the level the voltage
and the electric capacity distribution,enhanced the product tolerance atmospheric
overvoltage and switching surge impact ability greatly, simultaneously also
improved the electric field distribution. causes the product bureau to one’s limit
further to reduce.
4.It may dispose warm controls the system and the forced-air cooling installment,
in the load oversized time automatic start air blower cooling system, sharpens the
equipment load ability effectively.
