High Effiency 500 KVA 15KV Oil Immersed Transformer Adjustable For Building

 

 

Safe and reliable service
 
Reliability is the everlasting objective of our company, partial discharge of finished products are constantly kept below 100pC, ensuring that the transformers can be operated under long service voltage and occasional over-voltage without trouble. Low current density in winding conductor and appropriate cooling arrangement ensure that the winding temperature rise and top oil temperature rise are lower than that specified in the national standard by more than 5K and that the mechanical stress in winding conductor during short circuit does not exceed certain safe limit. Together with technological procedures during manufacture and other means to elevate mechanical strength, transformers can withstand server short circuit in all case during service
