Product Description

S-M 3000KVA oil immersed distribution transformers,13.8KV/0.415KV,60HZ,off load tape change 2*+-2.5%,Copper windings.Dyn11,ONAN, No load loss/loadloss=2380W/29300W, which has the most advanced tridimensional toroidal core instead of traditional laminated core. The MRL transformers are green and energy-saving, having the advantages of less loss, smaller no-load current, lower noise and compact size. 
They are the new and ideal distribution transformers for industrial and civil application, to step down grid voltage 10KV to line voltage 400V, which can serve both indoors and outdoors at an ambient temperature range -25ºC to 40ºC. With the new core structure, the transformers have better performance of withstanding of short-circuit and overload. 
Product standard:  IEC60076 & GB1094 and GB/T6451
