Structural Features

1. High purity oxygen free cooper windings, reduce the load loss

Inner coil was wound directly on the insulation barrel, where chamfering spacers and padding blocks are applied to uniform the electric field and enhance stability. And, BDK-80M synchronized lifting up equipment was applied in assembly to ensure the axial location of the windings and reinforce the axial strength.

2. Tank

Wide-width steel plate is adopted to reduce welding seams on the flat roof, folded plate type tank, it has concise and dedicate appearance and also high mechanical strength which passed the standard positive pressure and vacuum test. In addition, special welding technology and groove type flange ensure the tank and the pipes are able of long time use without leakage. Wide plate radiation system equipped with heavy duty and low noise blowers rises up the heat dissipating center, improve the efficiency, reduce radiating plates and prevent leakage. It can be directly mounted on the transformer. And capsule type conservator can effectively delay the aging of the oil what is implanted in under vacuum condition to reinforce the electric strength.
