3. Design and Structure of Pole Mounted Distribution Transformers
The structural design of a pole mounted distribution transformer directly affects installation safety and long-term reliability. The 150 kVA pole mounted distribution transformer features a compact tank structure optimized for overhead installation on wooden, concrete, or steel utility poles.
The transformer tank is manufactured from high-strength steel with anti-corrosion coating, making it suitable for harsh outdoor environments such as coastal regions, high-humidity tropical zones, desert areas, and industrial locations. Internally, the core and windings are securely fixed to withstand mechanical stress during transportation and operation.
Standard structural components include:
-
High-voltage and low-voltage bushings
-
Reinforced pole mounting brackets
-
Grounding terminals
-
Pressure relief and oil filling devices
-
Lifting lugs for easy handling
Customized structural drawings and mounting accessories are available from PowerNex to meet local utility installation practices.

4. Core, Coil, and Oil-Filled Cooling System
The performance of a 150 kVA single phase oil-filled distribution transformer depends heavily on its internal core and winding design. PowerNex uses high-grade grain-oriented silicon steel to manufacture the transformer core, reducing core losses and improving overall energy efficiency.
The windings are produced using high-conductivity copper or aluminum conductors, carefully insulated to handle thermal expansion and short-circuit forces. This design ensures stable operation under continuous load and during fault conditions.
The oil-filled ONAN cooling system provides:
-
Efficient heat dissipation
-
Excellent dielectric strength
-
Reduced insulation aging
-
Extended service life
As a result, the 150 kVA pole mounted distribution transformer maintains reliable performance even under fluctuating load and high ambient temperatures.
