The performance of our S9 S10 S11 series 20kV and 35kV three-phase oil-immersed transformer conform to the standard of GB 1094-1996 “Power Transformer “ and GB/T6451-2008 “Technical Parameter and requirements of Three-phase Oil-immersed Power Transformer”.
The iron core is made of quality cold –rolled silicon steel sheet , and the coil is made of quality oxygen-free copper, featuring good outlook and safe running.
The products are widely used in power transmission and distribution of industrial and agricultural power networks.
Iron core is made of cold-rolled silicon-steel sheet with high conduction of magnetism and adopts pulling-plank structure, so that its magnetic route is short, losses and noise level is low;
Compress wire is adopted for winding so losses are low and have good ability withstand short-circuit;
Its active part adopts special pressing method which could ensure reliable axial pressure;
The oil tank is bell type with the structure of full folding plate type, having an excellent exterior and easy for maintenance;
Reliability: All in-service product have no damages or oil leakage occurred;
Oil tank with various kinds of structure and good appearance.
