Overview
Advantages of Performance
The Altro TDT open ventilated transformer is not only green and energy saving but also fire-proof explosion-proof, dust proof, damp proof, better overload capacity and easy maintenance. The winding of the transformer has a high fire resistance and thermal shock resistance as they will not release harmful gas under 750℃. Furthermore, the windings can be repaired and replaced if any phases are broken.
Scope of Application
This transformer is suitable for the same application as the cast resin transformer. In addition to that, Open Ventilated Transformer can withstand a higher temperature of 220˚C (Class C) that is suitable for application in dessert areas or critical climate, smelting plant, iron & steel mill, casting plant and foundries.
