13.8KV 240V/480V 100KVA Oil Immersed Distribution Transformer Single Phase Pole Mounted Transformer

Overview of 13.8KV 240V/480V 100KVA Oil Immersed Distribution Transformer Single Phase Pole Mounted Transformer

An oil-immersed transformer is a type of electrical transformer where the core and windings are submerged in an insulating oil. This oil serves two primary functions: it acts as a highly effective insulator between conductive parts and as a coolant to dissipate heat generated during operation. These transformers are robust, reliable, and highly efficient, making them the standard choice for high-voltage power distribution and transmission networks, typically installed outdoors in substations.

Features of 13.8KV 240V/480V 100KVA Oil Immersed Distribution Transformer Single Phase Pole Mounted Transformer

• Effective Cooling: The insulating oil efficiently absorbs heat from the core and windings and transfers it to the radiator fins, allowing for natural or forced circulation and higher overload capacity.
• Superior Insulation: The oil provides much better dielectric strength than air, allowing for a more compact design for a given voltage rating and protecting against short circuits.
• Robust Construction: Designed for long-term, reliable operation (often 25-30 years) in harsh outdoor environments.
• Overload Capacity: Can handle temporary power overloads better than dry-type transformers due to the thermal mass and cooling properties of the oil.
• Protection System: Equipped with a conservator tank (to allow for oil expansion), breather (to absorb moisture from air), and protective relays (Buchholz relay) for internal fault detection.
• Cost-Effective: Generally more economical for high-power applications compared to dry-type transformers.

Specifications of 13.8KV 240V/480V 100KVA Oil Immersed Distribution Transformer Single Phase Pole Mounted Transformer

This transformer steps down high voltage power. It takes 13,800 volts on the primary side. The secondary side gives you two choices. You get 240 volts or 480 volts. The transformer capacity is 100 kilovolt-amperes (kVA). This is enough power for many homes or small businesses needing single-phase service.

The transformer core and coils sit inside a sturdy steel tank. The tank is completely filled with special insulating oil. This oil cools the transformer. The oil also provides excellent electrical insulation. The tank is welded shut for a permanent, leak-proof seal. A welded tank keeps moisture and air out. This protects the internal parts. The oil stays clean longer.

Heat builds up during operation. The oil absorbs this heat from the core and windings. The hot oil naturally rises to the top of the tank. Cooler oil sinks to the bottom. This natural flow circulates the oil constantly. The tank surface releases the heat into the surrounding air. This design keeps the transformer running cool. It handles hot weather well.

Safety is important. The transformer includes a pressure relief device. This device activates automatically. It releases pressure inside the tank if it gets too high. This prevents dangerous ruptures. It protects the transformer and nearby equipment. The device resets itself after operating.

This transformer mounts on a utility pole. Its design is compact and lightweight. This makes pole installation straightforward. It comes ready to connect. Terminals are accessible for primary and secondary wiring. The unit includes lifting hooks. These hooks make hoisting the transformer into position easier. The transformer meets standard temperature rise limits. It operates reliably for years. It provides dependable voltage conversion for overhead distribution lines.

Applications of 13.8KV 240V/480V 100KVA Oil Immersed Distribution Transformer Single Phase Pole Mounted Transformer

This transformer changes high voltage electricity to lower voltage power. It handles 13,800 volts on the input side. It outputs either 240 volts or 480 volts. Its capacity is 100 kilovolt-amperes (kVA). This is a single-phase unit. It is filled with insulating oil for cooling. It is designed for mounting directly on utility poles.

Its main job is distributing power safely. It steps down voltage from the primary distribution lines. This makes the power usable for homes and businesses. It is perfect for areas needing single-phase power. You see it often in rural locations. It serves smaller towns and neighborhoods too. It feeds power to groups of houses or small commercial buildings.

The core and windings sit inside a steel tank. This tank is filled with special transformer oil. The oil cools the transformer. The oil also provides vital electrical insulation. This design keeps the transformer running reliably. It handles outdoor conditions well. It withstands rain, wind, and temperature changes.

Mounting it on a pole saves space. There is no need for a ground-level pad. This keeps it away from people and animals. This enhances safety. The oil inside helps absorb heat generated during operation. This prevents overheating. Overheating can damage the transformer. The robust tank protects the internal parts. It shields them from weather and minor impacts.

This transformer connects directly to overhead power lines. It feeds lower voltage lines running to customers. Its size is practical for pole mounting. It is a common sight on distribution networks. Maintenance checks are important. Technicians check oil levels and connections regularly. This ensures long service life. It provides dependable power delivery day and night.
