Industrial Electrical Transformers 200kVA 315kVA 630kVA 10kV 11kV 0.4kV Three-Phase Oil-Immersed Transformer

Overview of Industrial Electrical Transformers 200kVA 315kVA 630kVA 10kV 11kV 0.4kV Three-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 Industrial Electrical Transformers 200kVA 315kVA 630kVA 10kV 11kV 0.4kV Three-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.

Applications of Industrial Electrical Transformers 200kVA 315kVA 630kVA 10kV 11kV 0.4kV Three-Phase Oil-Immersed Transformer

Industrial electrical transformers like the 200kVA, 315kVA, and 630kVA models are vital equipment. They handle voltages like 10kV, 11kV, and 0.4kV. These are three-phase oil-immersed units. They power many industrial operations. Factories rely on them heavily. Manufacturing plants need stable power for machinery. These transformers step down incoming high voltage. This makes the voltage safe for use inside the plant. They connect directly to motors, conveyors, and assembly lines.

Large commercial buildings also use these transformers. Think shopping malls, hospitals, and office complexes. They distribute power efficiently throughout the structure. The oil cooling system is key. It absorbs heat generated during operation. This keeps the transformer running reliably. It also helps the unit last longer. The 315kVA and 630kVA sizes are common for bigger facilities. They manage significant power loads.

Industrial parks and mining sites need robust power solutions. These transformers deliver. They handle tough environments. The oil insulation provides good protection. Construction projects often use them too. They provide temporary power for large sites. Water treatment plants are another application. Pumps and processing equipment need reliable power. These transformers supply it.

Renewable energy projects use these transformers. Solar farms and wind installations connect to the grid. They need voltage transformation. The 10kV or 11kV input is standard. The 0.4kV output powers local equipment. These transformers link the generation site to the main network. They are built for continuous duty. Their design prioritizes safety and efficiency. Installation is flexible. They work well outdoors in substations. They can also be placed indoors with proper ventilation. Maintenance is straightforward. This ensures minimal downtime. Power reliability is critical for industry. These transformers provide that essential service. They are a proven solution for medium-power distribution.

5 FAQs of Industrial Electrical Transformers 200kVA 315kVA 630kVA 10kV 11kV 0.4kV Three-Phase Oil-Immersed Transformer

What are these transformers mainly for?
These 200kVA, 315kVA, and 630kVA transformers power big industrial sites. Factories, mines, large buildings, and infrastructure projects use them. They step down high voltage electricity (10kV or 11kV) to the safer 400V used by heavy machinery and equipment. They handle the big loads these places need.

Will 10kV or 11kV input work?
Yes, these transformers are built for both. They are designed to work correctly with either 10kV or 11kV incoming power. You don’t need a different model. The transformer adjusts automatically to the supply voltage within this range. This makes them very flexible for different power grids.

Why use oil-immersed design?
Oil is great for cooling. Big transformers generate a lot of heat. The oil absorbs this heat efficiently. It keeps the internal parts much cooler. This prevents overheating and damage. The oil also provides excellent electrical insulation. This protects the transformer windings. This design is reliable and long-lasting for heavy industrial use.

What space is needed for installation?
These are large, heavy units. You need a solid, level concrete base. Allow enough space all around for airflow. Good ventilation is critical. The transformer needs room to breathe and stay cool. Also, leave space for future maintenance access. Think about how it will be delivered and placed. Plan the location carefully.

How often is maintenance required?
Check oil levels and quality regularly. Inspect for any leaks. Look at connections and bushings. Listen for unusual noises. Schedule professional checks at least once a year. More frequent checks might be needed in harsh environments. Proper maintenance is key for long life and preventing failures. Follow the manufacturer’s specific schedule.
