Features:
This power transformer is a transformer whose interior is isolated from the air surrounding, so that the transformer oil can not absorb the outer moisture and the oxygen since the change of transformer's volume could be fixed with the flexibility of corrugated tank structure. Then the aging speed of insulated material will be decreased. Before running the power transformer, the work of core suspension checkup is not necessary. Clients could also be free for the later maintenance and reparation. The reliability of this power transformer is visibly upgraded.

The coil is with high-intensity enameled wires (or paper wrapped wired) in bucket form or cake form, which is evenly coiled and installed. Its insulation structure is reasonable and it has strong anti-shortcut capacity. All the screws will not become loose after long journey. All sealed parts use rubber, which could effectively anti-aging by heat, light and electricity. Also the remote controlled thermometer and pressure release valves increase the reliability of the power transformer.
