| Only first choice core laminations varnished
with low loss or with oriented grains are used for its fabrication.
For primary winding, double isolated copper thread or metal
straps are used, and during the winding process it is resin-bonded
again, as well.
The secondary winding always in copper ribbon, beginning
with 15 KVA, is always cooled using circulating water.
The finished transformer is impregnated with epoxidated resins
to eliminate cavities and air bubbles.
More controls are handled during its fabrication:
- Immediately following the primary winding
- Once the transformer has been completed with secondary
winding and core laminator
- Prior to the resin casting
- Installed in the machine
The available strengths are single-phase
2,4,8,13,22,38,45,60,80
KVA and triple-phase
15, 40,70,100,220 KVA. |
