Three phase SG isolation transformer and three phase SOG auto-transformer-8

Isolation transformer are important component parts in various power supply and electric appliance, We have applied advanced technological process for transformer manufacture, such as Arrangement wire winding without bobbing, the whole transformer is impregnated under vacuum-pressure up to insulation class F or H. The input and output voltage can be designed as required. There are various dry-type transformer of single phase or three phase with delta, Y and Yo connection or special for multi-input or output is available.

Thedry-type transformer have been designed and produced by our factory for over 15 years. It is suitable used for electric circuit of AC 20Hz to 400Hz and voltage below 1000V, and is wide used in electric appliance for light, lift, machinery, medicine device, electro plating, rectifier and power supply etc. The specifications can be designed and satisfied for custom's special requirement.

Features and benefits:

• High level of isolation
• High quality neutral-ground bond
• High level of common-mode noise rejection
Conversion from Delta to Wye or the other way around
• Easy to change voltage taps
• Custom design for specific system

Applications:

• Integrated in power conditioner at input or output.
• Any system requires isolation and shielding.

Operating environment
1)Temp.:The ambient temperature can not over +40℃。
2)Altitude: Mounting location can not exceed the altitude of 2000m
