Outdoor 3 Phase Power Electrical 11kv 33kv 50kva 100kva 200kva 300kva 400kva 1000kva 630kva Oil Immersed Transformer

Overview of Outdoor 3 Phase Power Electrical 11kv 33kv 50kva 100kva 200kva 300kva 400kva 1000kva 630kva 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 3 Phase Power Electrical 11kv 33kv 50kva 100kva 200kva 300kva 400kva 1000kva 630kva 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.

This transformer handles outdoor power distribution. It works with 11kV or 33kV electrical systems. Various sizes are available: 50kVA, 100kVA, 200kVA, 300kVA, 400kVA, 630kVA, and 1000kVA. The core and windings sit inside a strong steel tank. This tank holds special insulating oil. The oil does two main jobs. It cools the transformer effectively. It also provides vital electrical insulation.

The steel tank protects the internal parts. It withstands tough weather conditions. Rain, dust, and wind won’t harm it. The design prevents leaks. The oil level stays stable. External cooling fins or radiators attach to the tank. These increase the cooling surface area. Heat dissipates efficiently. The transformer stays cool even under heavy load.

Terminals are clearly marked. They connect high voltage and low voltage lines. Bushings are made from durable porcelain or polymer. These insulate the terminals. They prevent electrical flashover. An oil conservator tank is usually present. It allows for oil expansion as temperatures rise. An oil level gauge shows the current oil volume. A pressure relief device protects the tank. It vents safely if internal pressure gets too high.

This transformer is built for reliability. It operates continuously outdoors. It handles temperature extremes. High ambient heat or freezing cold won’t stop it. High humidity environments are also suitable. It requires minimal maintenance. The robust oil-immersed design ensures long service life. It steps down voltage for industrial sites, substations, or remote areas. Performance meets international standards. Safety features protect the equipment and personnel.

Applications of Outdoor 3 Phase Power Electrical 11kv 33kv 50kva 100kva 200kva 300kva 400kva 1000kva 630kva Oil Immersed Transformer

These outdoor transformers handle big power jobs. They take high voltage electricity from the grid. They step down this voltage. They make it usable for factories, towns, and other large places needing lots of power. You see them at 11kV or 33kV input levels. Their capacity ranges widely. Choices include 50kva, 100kva, 200kva, 300kva, 400kva, 630kva, and 1000kva models. This covers many different power demands.

Industrial sites rely heavily on them. Factories need steady, high-capacity power for heavy machinery. These transformers provide that. They are built tough. They sit outside substations. They connect directly to the main power lines feeding an industrial park or a large manufacturing plant. Mining operations use them too. Mines need robust power solutions in remote, harsh areas.

Renewable energy projects need them. Solar farms generate power. Wind farms generate power. This power often needs stepping up for transmission. Sometimes it needs stepping down for local use. These transformers manage that voltage change efficiently. They are placed right at the generation site or at substations nearby.

Utility companies install them everywhere. They form the backbone of the electricity distribution network. You find them on poles. You find them on concrete pads near neighborhoods. They feed power to entire sections of a city. They supply smaller substations. They supply large residential complexes. Construction sites use temporary versions. They power big equipment before permanent lines are ready.

The oil inside is key. It cools the transformer windings. It insulates them. This oil cooling allows the transformer to handle high loads. It prevents overheating. The sealed tank protects the oil. It keeps out moisture and dirt. This design ensures long life outdoors. They withstand rain, wind, and temperature swings. Safety features are built-in. Pressure relief devices protect against internal faults. Monitoring points allow for easy checks. Their reliability is critical. Power outages cost money. These transformers keep the electricity flowing where it’s needed most.
