50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva 20kv Oil Immersed Electrical Power Distribution Transformer

Overview of 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva 20kv Oil Immersed Electrical Power Distribution 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 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva 20kv Oil Immersed Electrical Power Distribution 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.

5 FAQs of 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva 20kv Oil Immersed Electrical Power Distribution Transformer

What does this transformer do?
This transformer changes electricity voltage levels. It steps down high voltage electricity to safer, usable levels for homes, factories, and businesses. It handles power from 50,000 watts (50kVA) up to 500,000 watts (500kVA). The 20kV rating means it connects to a 20,000-volt power line. Oil inside cools it and provides electrical insulation.

Where is this transformer typically used?
You see these transformers in many places needing reliable power distribution. They work well for industrial plants, large commercial buildings like shopping malls, hospitals, data centers, utility substations, and housing developments. They handle the significant power demands of these locations efficiently.

How should it be installed safely?
Installation needs careful planning. Place the transformer on a strong, level concrete pad. Ensure good airflow around it for cooling. Keep it away from things that can burn. Only trained electricians should connect the high-voltage cables. Follow all local electrical codes and safety rules exactly. Grounding the transformer properly is critical for safety.

What maintenance does it require?
Regular checks keep it running reliably. Inspect the oil level often. Look for leaks around the tank and bushings. Test the oil quality periodically to check its insulating strength. Clean the outside surfaces to prevent dirt buildup. Listen for unusual noises like humming or cracking. Schedule professional inspections yearly or as the manufacturer recommends.

How efficient is this transformer?
These oil-filled transformers are designed for good efficiency. They lose very little power during normal operation. Higher kVA models (like 400kVA or 500kVA) often run more efficiently under heavy loads than smaller ones. Less wasted energy means lower electricity costs over the transformer’s long life. Energy efficiency is a key benefit.
