Step Up Dry Transformer - China

price: contact company for price

Structural Characteristics:

Foil Coil: Adopting the entire section of copper foil, together with the F-class turn insulation, low voltage winding is wound by the special low-voltage foil winding machine.

The foil coil resolves problems such as large short-circuit stress, ampere turn unbalance, poor heat dissipation, existing the winding spiral angle and unsteady manual welding quality due to low voltage and large current coil.

At the same time, the end of winding is treated with cast resin, solidificationto makeshape, moisture-proof and anti-fouling, the lead for copper bar is welded by argonarc welding automatically.

Temperature Control Device: the transformer adopts BWDK series of signal thermometer.

The temperature components are embedded in the upper half of the low-voltage coil, can detect and display the temperature of separate phase coil automatically and continuously, also have the functions of over-temperature alarm and trip.

We are pleased to deliver Transformer, Distribution Transformer, Power Transformer, Oil Transformer, Dry Type Transformer.

Safe payment and on time deliver time will give you.
