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 andmoremany projects.Its main meritincludes:
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,reduces the lineloss,reduces the line movement cost.
5.The 35KV,20kV power source enters directly uses electricity the center,enhances the power supply effectively the reliability.
Product features
Our company products SCB10 the series 20KV level,the 35KV level adjust the dehydration pressingtype transformer without the excitation to be the low loss product,conforms to national standards GB/T1094.11,GB/T10228 and the IEC60076.11 request,and has following characteristic:
1.The high performance,the low loss,is 9 series update products.
2.Selectsthe 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.
