Introduction

Product introduction (SG Three-phase dry type transformer)

DG and 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 distribution places 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.

Working environment (SG Three-phase dry type transformer)

1.Ambient temperature: -15℃~+40℃
2.Altitude: <1000m
3.Relative humidity: <90%
4.Environment exists without gas, steam, chemical deposition, dust or dirt that will affect transformer's insulation seriously, also explosive or corrosive medium is not
allowed.
5.If any special working conditions that are not in line with the above stipulations,
user shall negotiate with us.
