100kVA 11kv Oil Immersed Power Transformer/Distribution Transformer

100kVA 11kv Oil Immersed Power Transformer/Distribution Transformer

 Advantage:

1. we employ sprial coil with longitudinal oil path to make a better interior cooling effect;
2. we improve the effective support of the coil's terminal surface to strengthen the anti-short circuit current capability;
3. we employ new hoisting structure and body-positioning frames to guarantee that the long distance transport and movement will be more reliable;
4. cancelled the oil tank, the wave wings of tank instead of the tubing as a cooling device, corrugated tank is made of high quality cold press sheet on dedicated machine and enhance the reliability of running.

Typical test values and performances are performed in the painting lab on steel plates during the whole painting process in order to confirm the following:
• Minimum paint thickness film (ISO 2808): 70µm
• Specular gloss factor at 60 Deg (ISO 2813): 90 +/- 5%
• Falling weight test (ISO 6272): 1Kg/050cm
• Erichsen cupping test (ISO 1520): 08mm
• Scratch test (Adhesion ISO 2409): 0
• Bend Test (cylindrical mandrel ISO 1519): 3,0mm
• Salt spray (Fog) test (ISO 7253): Over 1000 Hours
