Transformer Single Phase 100KVA Pole Mounted Transformer
Distribution
Summarization
Single phase pole mounted transformers designed and produced by
WINLEY are normally used for stepping utility distribution
voltages(from 2400V to 34500V) down to lower utilization voltages.
Although some are used for stepping down to commercial and
industrial voltages such as 277V, 240/480V, 2400V and 4800V, most
are used for stepping down to the single phase voltage of 120/240V.

Pole Mounted Transformer Key Craft
1. Magnetic circuit design
The iron core's shape, size, hysteresis, and eddy current loss are
important factors to consider. Properly designing the magnetic
circuit can lead to efficient energy transmission and reduced loss.
2. Winding design
Factors such as the number of turns, wire material, interlayer
insulation, and wiring method should be taken into consideration
during the design process. By implementing a well-planned winding
design, the transformer can achieve greater load capacity and
reliability.
3. Insulation material selection
Choosing the right insulation materials is paramount to ensure
safety and longevity. It's essential to opt for insulating
materials that offer excellent insulation performance,
high-temperature resistance, arc breakdown resistance, and moisture
resistance.
4. Vacuum oil filling
Single-phase pole-mounted transformers typically utilize a vacuum
oil filling method. This involves treating the transformer chips
with a vacuum, injecting insulating oil, eliminating air bubbles,
and sealing the transformers. The vacuum oiling process is
beneficial as it enhances the insulation performance and thermal
stability of the transformer, leading to prolonged service life.
5. Heat treatment
Transformers' mechanical properties and strength can be enhanced
through heat treatment. This process alters the material's
organizational structure, boosting its hardness and wear resistance
while reducing stress and deformation.
