75-KVA MONO PHASE TRANSFORMER

THREE-PHASE TRANSFORMER

These are dry-type three-phase safety and isolation transformers designed for general use. They are used when voltage conversion or electrical isolation is needed. They serve as an effective protection device against permanent injuries or fatal accidents caused by electric shock. The insulation between the windings and the core is highly durable, providing short-term resistance to high power levels. They can be manufactured in different power ratings and voltages according to customer requirements.
