Technical Data Sheet

750 KVA dry type transformer specifications and data sheet

Finished 750 KVA 6.6/0.55KV Transformer

The coil is reinforced with glass fiber, and the whole process of pouring and curing with epoxy resin filled in vacuum is monitored at the computer terminal at any time and automatically adjusted by the computer according to the situation. The precise manufacturing process makes the coil have good mechanical properties, no cracking, no bubbles inside, small local discharge, high reliability and long service life.

The Feature of Dry Type Transformer:

1. This product has good moisture-proof performance. The high and low-voltage coils are vacuum cast without moisture absorption, and the iron core clamps and fasteners are treated with anti-corrosion, which can operate in high temperature and harsh environment.

2. Flame retardant, explosion-proof, no environmental pollution.

3. The internal embedded air duct enhances the heat dissipation performance and overload capacity.

4. With low loss, low noise and core stacking, fully inclined 45 ° joint and step lamination are adopted, which can effectively improve the magnetic flux distribution at the core corner, reduce the no-load loss step by step, and greatly reduce the noise level.

5. It has excellent ability to resist short circuit and lightning impact.

6. Small size, light weight, simple installation, wide range of application; safe and reliable, maintenance free, low comprehensive operation cost.
