400 Kva 500kva 630 Kva 1500 Kva 3 Phase Oil Immersed Distribution Transformer

Overview of 400 Kva 500kva 630 Kva 1500 Kva 3 Phase Oil Immersed 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 400 Kva 500kva 630 Kva 1500 Kva 3 Phase Oil Immersed 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.

Applications of 400 Kva 500kva 630 Kva 1500 Kva 3 Phase Oil Immersed Distribution Transformer

These transformers handle big power jobs. They take high voltage electricity and make it lower voltage. This is for factories, buildings, places needing lots of power. The transformer core sits inside a strong steel tank. The tank is filled with special insulating oil. This oil cools the transformer. The oil carries heat away. This keeps things working right. It stops the transformer from getting too hot. These transformers are built tough. They handle daily use well. They last a long time. They work in different weather. Hot days, cold days, they keep going. They are reliable equipment.

Sizes include 400 kVA, 500 kVA, 630 kVA, up to 1500 kVA. These sizes suit many industrial needs. Use them in manufacturing plants. They power heavy machinery. Use them in large commercial buildings. They run lighting, HVAC systems, elevators. Use them for water treatment plants. They run pumps and controls. Use them for mining operations. They power drills and processing equipment. Use them with renewable energy sites. They connect solar farms or wind farms to the grid. They step up voltage for efficient transmission. They step down voltage for local use.

The oil insulation is key. It handles high voltages safely. It makes the transformer more efficient. Less energy is lost as heat. The steel tank protects the inside parts. It keeps dirt and water out. The design allows for easy maintenance. Technicians can check oil levels. They can test oil quality. They can inspect connections. This helps prevent problems. It keeps the transformer running smoothly for years. These units meet strict safety standards. They are built for stable operation. They provide consistent voltage output. This protects sensitive equipment downstream. They are a practical solution for serious power distribution.

5 FAQs of 400 Kva 500kva 630 Kva 1500 Kva 3 Phase Oil Immersed Distribution Transformer

What are these transformers mainly used for?
These oil-filled transformers handle big power jobs. They step down high voltage electricity to safer, usable levels. Factories, large buildings, mining sites, and substations rely on them. They power heavy machinery and large equipment reliably.

Are they safe to use?
Yes, safety is built-in. They follow strict safety rules. The oil inside cools the transformer and stops sparks. Strong tanks contain the oil. Protection devices like pressure relief valves are included. They are built tough for outdoor use in tough weather.

How much maintenance do they need?
They need regular checks, but not constant work. Technicians test the oil quality and check connections. They look for leaks and clean parts. Good maintenance keeps them running efficiently for many years. Follow the maker’s schedule closely.

How efficient are these transformers?
They are built for high efficiency. Less energy gets wasted as heat. This saves money on electricity bills over time. Their efficiency meets or beats standard energy ratings. Good design and quality materials make this possible.

Can they be customized for my needs?
Yes, customization is common. Voltage levels can be set for your specific grid. Options include different types of cooling radiators or special protection devices. You can choose specific cable connection boxes too. Tell the supplier your exact requirements.
