• MANUFACTURING STANDARDS
• The transformers described in this catalogue are designed and tested in accordance to the European Union Harmonisation Documents HD 538 and HD 464 as well as IEC 726, IEC 76. standards. However, and by request, they can be manufactured according to other national or international standards. 

• RATINGS  100 - 160 - 200 - 250 - 315 - 400 - 500 - 630 - 800 - 1000 - 1250 - 1600 - 2000 - 2500 - 3000 - 3500 KVA .
• HIGH VOLTAGE
• This material is designed for voltages of ≤ 36 kV. Specific figures are not given for this parameter because of the wide variety of voltages used. Transformers can be supplied on demand to run at two different primary voltages.
• LOW VOLTAGE
• The no load low voltage is allocated at 420 V, though other voltages can be supplied on demand. When usage requires two voltage
• transformers with two simultaneous voltages can be supplied. In this case the no-load voltages are set to 420 and 242 V.

 

SPECIAL PURPOSE EPOXY CAST RESIN TRANSFORMER
