General
SG
series single-phase and three-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.
