Product introduction

    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.Its main merit indludes:

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 the power supply effectively the reliability.

Characteristics of the product

    The SC(B)10 series 20kV, 35kV non-excitation voltage regulation dry transformer produced by our company is a low loss product.
In line with the national standards GB6450, GB/T10228 and IEC726 requirements, and has the following characteristics:
1. High performance, low loss, for the type 9 series replacement products.
2. The selection of high-quality silicon steel sheet, while greatly reducing the magnetic flux density, reduce the operation of silicon steel sheet magnetostrictive weight, effectively reduce noise c
3. Optimize the high-voltage coil structure, improve the distribution of interlayer voltage and capacitance, greatly improve the impact ability of the product to withstand atmospheric overvoltage and operating overvoltage, and also improve the electric field distribution, so that the product is further reduced.
4. Temperature control system and air cooling device can be configured to automatically start the fan cooling device when the load is too large, effectively improving the overload capacity of the equipment.
