Description

SBK/SG/GSG three-phase dry type transformer General (DG and SG series single-phase and 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, is mainly used in power supply occasions of AC *0~*0Hz and voltage less than **0V. All the input and output voltage , connection group and capacity of tapped winding can be designed and produced according to users&#**9; requirements. Working conditions (DG and SG series single-phase and three-phase dry type transformer) 1.Ambient temperature: **5â??~**0â?? 2.Altitude: <***0m 3.Humidity: <*0% ***** without gas, steam, chemical deposition, dust or dirt that will affect transformer&#**9;s insulation seriously, also explosive or corrosive medium is not allowed. 5.Any special working conditions that are not in line with the above stipulations, user shall negotiate with us. Main technical characters (DG and SG series single-phase and three-phase dry type transformer) ***** voltage: rated voltage ?*0% ***** voltage: rated voltage *5% (no load) *****: â?¥*5% 6.Waveform distortion: no additional waveform distortion *****: indication of input voltage, output voltage and current. 7.Protection: over-current protection ***** operate itself without anybody attending for a long term ***** resistance: â?¥*0MΩ ***** strength: no breakdown or flashover phenomenon under power frequency sine voltage of ***0V for 1min ***** capability: for 1min under two times of rated current
