My company has been using high quality materials and advanced technology specializing in the production of poles between 160VA to 600KVA ,SG series three-phase transformer , the company is the latest reference to similar products Siemens CNC system developed transformers, especially between 160VA -16KVA the three-phase transformer, their shape and installation dimensions have been standardized, and Siemens 4AP series Universal products meet VDE0550, IEC439 , JB5555, GB226 and other international and national standards.



The series three phase dry type transformer are widely used in AC 50~60HZ, input, output voltage does not exceed 500V three-phase supply various occasions. Products, a variety of input and output voltage level, join groups, tap the number and location (typically ±5%),winding capacity allocation, the secondary winding single-phase equipment, rectifier circuit, is required with housing, etc. Can according to user demands meticulous design and manufacturing.

This series three-phase rectifier transformer for rectifier equipment, made after charging rectifier, voltage regulator and DC power supply purposes.

Working Environment:

  • Ambient air temperature: -5.C~+40.C,the highest monthly mean temperature should not exceed +30.C;

  • Altitude for installing place should not exceed 2000m;

  • When the ambient air temperature is +40.C the relative humidity should not exceed 50%, and it allows higher relative humidity under lower temperature, Max average humidity in the dampest month is 90%, meanwhile the lowest average temperature of this month is +25, and condensation on the product surface cause by temperature change should be taken into consideration on the product surface caused by temperature change should be taken into consideration.



  • Before youare using a good estimate total electrical capacity and use a considerable capacity of the transformer, ensure instantaneous starting not burn transformer;

  • The transformer in strict accordance with the relevant national standards design and production. When youuse multiple winding (multi control voltage) transformer, the capacity should be a corresponding increase in capacity of transformer voltage ratio, so as not to burn the transformer;

  • The installation, you should carefully check whether the date listed in the nameplate meet your requirements, after confirmation, before installation;

  • Power work, the transformer core and coil will generate heat (but the temperature does not exceed 80.C)is a normal phenomenon, if the temperature exceed 80.C,even smoke, you should cut off the power switch, re-check your electrical capacity used;

  • In transit should be possible to avoid a collision, not damp, when used, please note that maintenance to protect the transformer life.
