Cast – Resin Distribution Transformer ( Dry Type )
The cast resin transformers are manufactured in accordance with the IEC-76, IEC-726 standards and ranged from 100 up to 3150KVA voltage and of nominal voltage of 15-20/0,4 ΚV. ( Different powers and voltages upon request ).
They are placed indoors or outdoors in a special cover.
The medium and low voltage windings are made of aluminum.
Cooling is performed with natural air circulation.
Dry type transformers are disposed with the following equipment:
Connection bars of medium – low voltage.
5 positions voltage switch selector ( ± 2×2,5% ).
Electronic high temperature protection relay with possibility to program four contacts ( alarm, decoupling, fault indication, fan control ).
