The Single Phase Pole Mounted Cylindrical Transformer is a high-reliability overhead distribution transformer designed for rural electrification, utility grids, and industrial auxiliary power supply systems. Engineered in compliance with IEC60076 standards, it provides stable voltage conversion from medium voltage (e.g., 11kV, 13.2kV, 22kV, 33kV) down to low voltage (230V / 240V / 110V) for end-user distribution.

This transformer adopts a sealed cylindrical tank design with high IP protection rating, ensuring superior resistance against moisture, corrosion, salt fog, dust, and extreme tropical climates. It is widely used in Southeast Asia, Africa, Latin America, coastal regions, and high-humidity environments where reliability and low maintenance are critical.

Our factory provides fully customized solutions including voltage rating, insulation class, bushing type, surge protection, and mounting structure.

• Tropical & Coastal Climate Adaptation – Anti-corrosion coating, stainless steel fasteners, and enhanced insulation system for high humidity and salt-air exposure.
• Low Loss & High Efficiency Core – Grain-oriented silicon steel core minimizes no-load losses and improves energy efficiency for utilities.
• Maintenance-Free Sealed Design – Fully sealed cylindrical tank reduces oil oxidation and minimizes maintenance requirements.
• Flexible Custom Engineering – Voltage levels, kVA ratings, bushings, and surge protection devices can be customized for EPC project requirements.

• Frequent transformer overheating due to extreme ambient temperatures
• High humidity causing insulation degradation and partial discharge risks
• Coastal salt corrosion leading to tank rusting and leakage risks
• Lightning surges damaging distribution networks
• Short service life of conventional open-type pole transformers

1. Anti-Overheating Design
Optimized core-loss reduction structure and enhanced oil circulation system ensure stable thermal performance under high ambient temperature conditions.

2. Tropical Insulation Reinforcement
High-grade insulation paper and varnish treatment improve dielectric strength and reduce partial discharge in humid environments.

3. Corrosion Protection System
Epoxy anti-corrosion coating + stainless steel hardware + sealed cylindrical tank structure to resist salt fog and coastal corrosion.

4. Fully Sealed Tank Technology
Prevents moisture ingress and oxygen contact with insulating oil, significantly extending transformer lifespan.

5. Lightning & Surge Protection Integration
Optional surge arresters and reinforced insulation coordination improve grid reliability in lightning-prone regions.
