S  11-M - R - (No.1) / (No.2)

S    ---   Three Phase Oil-filled Transformer
11  ---   Code of performance level            
M   ---   Enclosed Structure                        
R   ---   Winding Iron Core
           (the one without R is just a non-winding iron core)
(No.1)  ---    Rated Capacity (kva)                          
(No.2)  ---     Voltage Class(kv)

Main Function and Features

01)    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;
02)      Compress  wire  is  adopted  for  winding  so  losses  are  low  and  have  good  ability  withstand short-circuit;
03)   Its active part adopts special pressing method which could ensure reliable axial pressure;
04)   The oil tank is bell type with the structure of full folding plate type, having an excellent exterior and easy for maintenance;
05)   Adopting capsule-type oil container, it can reduce oil aging to the lowest degree.

06)   Amount of local discharged:   The apparent discharge amount is less than 80pC under the 1.5 times of rated voltage;
07)   Noise: Products of 63MVA and below is lower than 58dB (AN);

08)   Power loss: no-load loss is 30% lower than that of IEC standard;

09)   Reliability: All in-service products have no damages or oil leakage occurred;

10)   Oil tank with various kinds of structure and good appearance.
