General
DG series single-phase
dry type transformer adopts high quality material and advanced technology,it has
advantages of damp-proof and convenient maintenance,it can be applied to such
power transmission and distributionplaces like underground railway,high
building,airport,station,wharf,enterprise,tunnel,etc.It is mainly used in power
supply occasions of AC 50-60HZ and voltage less than 500V.All the input and
output voltage,connection group and capacity of tapped winding can be designed
and produced according to users’requirements.
