Applications of Oil Immersed Cooling Transformer 100kva 12.47kV/13.2kV/13.8kV 0.4kV Single Phase Pole Mounted Distribution Transformer

This 100kVA oil immersed cooling transformer steps down medium voltage power (12.47kV, 13.2kV, or 13.8kV) to a safe, usable low voltage (0.4kV) for single-phase applications. Its pole-mounted design makes it ideal for distributing power directly where people need it. You see these transformers frequently along streets and roads in neighborhoods. They power homes, small businesses, and streetlights reliably.

Its key role is bringing electricity from the main power lines down to the level appliances and equipment use. The oil inside acts as both a coolant and an insulator. This natural cooling method keeps the transformer running smoothly under normal load conditions. It prevents overheating effectively. This design ensures stable voltage supply for end-users.

These units are particularly important in rural areas and smaller communities. They deliver power efficiently over the last stretch of the grid. Their rugged construction handles outdoor conditions well. Rain, wind, and temperature variations don’t affect performance significantly. The oil bath protects the core and windings from moisture and dirt ingress. This protection extends the transformer’s working life considerably.

The pole mount installation saves space. It avoids the need for a ground-level pad or enclosure. Utility crews find them straightforward to install and maintain. Their simple, robust design minimizes upkeep needs. Reduced maintenance means lower long-term costs. This reliability is crucial for continuous power delivery. The oil cooling system operates silently. This is a benefit in residential zones. These transformers form a dependable backbone for local electricity distribution networks. They provide essential service day after day.

5 FAQs of Oil Immersed Cooling Transformer 100kva 12.47kV/13.2kV/13.8kV 0.4kV Single Phase Pole Mounted Distribution Transformer

What voltages does this transformer handle?
This transformer connects to primary voltages like 12.47kV, 13.2kV, or 13.8kV. It steps down the voltage to 0.4kV (400 volts) for local distribution. The specific primary voltage depends on your local power grid requirements. Confirm the needed input voltage before ordering.

How does the oil cooling work?
The transformer core and windings sit inside a tank filled with special insulating oil. This oil absorbs heat generated during operation. The heated oil rises naturally. It cools down as it moves through the tank and radiator fins. Then the cooler oil sinks back down. This cycle keeps the transformer at safe operating temperatures.

Is this transformer safe?
Yes. The robust steel tank protects the internal parts. The insulating oil prevents electrical faults. The tank is sealed to prevent oil leaks. It also minimizes fire risk. These transformers meet strict safety standards for pole-mounted equipment. They are designed for reliable outdoor use.

Where is this transformer installed?
It mounts directly onto utility poles. This design saves ground space. It is common in residential areas, small towns, and rural settings. Installation requires trained utility personnel. They secure the transformer high on the pole using sturdy hardware. This keeps it away from public access and potential damage.

What maintenance does it need?
Routine checks are essential. Technicians visually inspect the tank for leaks or damage. They check oil levels through the gauge. Oil samples might be taken periodically for testing. This checks the oil’s insulating quality. Internal parts rarely need direct maintenance. Professional servicing ensures long life and prevents failures.
