Outdoor Installation Transformer Energy-Saving High Voltage 25KVA 17.5KV 0.23KV Single-Phase Oil Immersed Transformer

Overview of Outdoor Installation Transformer Energy-Saving High Voltage 25KVA 17.5KV 0.23KV Single-Phase Oil Immersed 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 Outdoor Installation Transformer Energy-Saving High Voltage 25KVA 17.5KV 0.23KV Single-Phase Oil Immersed 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 Outdoor Installation Transformer Energy-Saving High Voltage 25KVA 17.5KV 0.23KV Single-Phase Oil Immersed Transformer

This transformer is for outdoor use. It handles high voltage electricity safely. Its capacity is 25 kilovolt-amperes (KVA). This unit steps down voltage. It takes incoming power at 17,500 volts (17.5KV). It delivers usable power at 230 volts (0.23KV). This is a single-phase transformer. It suits many smaller power needs.

The transformer core uses high-grade electrical steel. This steel minimizes energy lost as heat. Copper windings conduct the electricity efficiently. The entire active part sits inside a strong steel tank. This tank is filled with special insulating oil. The oil cools the transformer. The oil also provides vital electrical insulation.

A sturdy base allows secure mounting. This base works on poles or concrete pads. The unit withstands tough weather. Rain, wind, and sun won’t damage it. The tank is sealed well. This prevents moisture getting inside. The oil level stays stable. The transformer operates reliably for years.

This design saves significant energy. Reduced core and copper losses mean less wasted power. Lower losses also mean less heat generated. The oil cooling works more effectively. The transformer runs cooler overall. This improves its lifespan. Efficiency is a key benefit. Using less energy saves money. It also helps the environment.

Safety features are built in. The tank is grounded properly. This protects against electrical faults. High-voltage bushings safely bring the wires in and out. Low-voltage bushings connect the output power. The oil itself is a natural fire retardant. This adds another safety layer. The transformer meets important electrical standards. It ensures safe operation for people and equipment. Regular maintenance checks are still needed. This keeps performance optimal.

5 FAQs of Outdoor Installation Transformer Energy-Saving High Voltage 25KVA 17.5KV 0.23KV Single-Phase Oil Immersed Transformer

Here are 5 common questions about the Outdoor Installation 25KVA Single-Phase Oil Immersed Transformer (17.5KV/0.23KV):

What is this transformer used for? This transformer steps down high voltage electricity. It takes 17,500 volts from power lines and converts it to 230 volts. This lower voltage is safe for homes and small businesses in rural areas. It’s built for outdoor use, often mounted on utility poles.

Why are the input and output voltages specific (17.5KV/0.23KV)? These voltages match common utility standards. The 17.5KV input connects directly to many distribution lines. The 0.23KV output provides standard single-phase power for end users. This compatibility ensures easy integration into existing power grids.

How does this transformer save energy? Its core uses advanced grain-oriented electrical steel. This special steel reduces energy lost as heat inside the transformer. Less energy wasted means lower operating costs over its lifetime. It performs better than older transformer models.

What are the key installation requirements? This transformer is designed for outdoor mounting on poles or pads. Proper grounding is essential for safety. Only qualified electricians should handle the high-voltage connections. The oil tank must remain sealed and leak-free. Follow all local electrical codes precisely.

What maintenance is needed? These transformers need very little routine maintenance. Their sealed, oil-filled design protects internal parts. Technicians should check the oil level periodically. They should also inspect for leaks or physical damage. The oil itself may need testing or replacement after many years.
