With the popularization and application of dry-type transformers, its manufacturing technology has also developed, dry-type transformer development advantages in many aspects, as follows:
1. energy-saving low noise:
With the introduction of new low-cost silicon steel sheet, environmental protection requirements, and the introduction of new materials, new processes and new technologies, transformers are more energy efficient and more quiet.
2. high reliability:
Improve product quality and reliability, will be the tireless pursuit of people. In the electromagnetic field calculation, wave process, pouring process, hot temperature rise, quality assurance system and reliability engineering, actively carry out reliability certification, to further improve the reliability and service life of dry-type transformers.
3. environmental certification features:
Carry out dry-type transformers weather resistance, resistance to environmental and fire resistance of the research and certification.
4. large capacity:
From 50 ~ 2500kVA distribution transformer-based dry-type transformers expand to 10000 ~ 20000kVA / 35kV power transformer, with the increasing load of urban electricity, city network area substation more and more in-depth city center area, 35kV large-capacity residential center power transformer will be widely used.
5. multi-functional combination:
From a single transformer develop to a wind turbine, protective shell, temperature computer interface, zero sequence transformer, power metering, closed bus and side outlet and other multi-functional modular transformer.
6. multi-field development:
From the distribution transformer to the main power plant plant transformers, excitation transformers, subway traction rectifier transformers, high current electric furnace transformers.
