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.

Below’s the item web content for those oil-immersed distribution transformers:

This array covers 400 kVA, 500 kVA, 630 kVA, and 1500 kVA oil-immersed circulation transformers. They are developed for three-phase power systems. These systems step down high voltage to usable levels for manufacturing facilities, buildings, and various other big centers. They are trustworthy and reliable for constant operation.

The core uses state-of-the-art grain-oriented silicon steel. This reduces energy losses. The windings are copper or light weight aluminum. They are meticulously wound and protected. The entire active component rests inside a strong steel storage tank loaded with protecting oil. The oil cools the transformer. It additionally gives insulation.

Cooling is ONAN type. That means oil all-natural flow and air natural air conditioning. Radiators placed on the tank help dissipate warm. Larger kVA units like the 1500 kVA have larger radiators. They require a lot more cooling surface area.

Standard primary voltage ratings are common. Believe 11kV, 22kV, or 33kV. Additional voltage is usually 400V or 415V. Various other voltages are feasible. The tap changer is usually off-circuit. It enables little voltage modifications throughout upkeep. This aids match regional grid conditions.

The transformer container is durable bonded steel. It secures the core and windings. Bushings bring the high and low voltage links securely out of the storage tank. Larger transformers make use of larger bushings. They handle the higher present securely. The container includes necessary installations. An oil level gauge shows the oil quantity. A stress relief tool shields against inner mistakes. A drainpipe valve permits oil tasting and modifications. A thermometer indicates oil temperature level.

These transformers fulfill worldwide requirements for safety and security and performance. They are created for long service life with appropriate maintenance. They take care of demanding commercial environments well.

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

These transformers deal with hefty power work. They tip down high voltage electrical energy to safer, functional levels. Factories use them daily. Large plants require the 1500kva versions. They power large equipments easily. Building sites commonly use the 400kva or 500kva sizes. They offer steady power for devices and temporary setups.

Huge structures depend on them also. Mall, health centers, workplace towers need regular power. A 630kva unit typically works well below. It powers lighting, elevators, cooling efficiently. The oil inside cools everything effectively. This stops overheating during lengthy hours. It makes the transformer last longer.

Renewable energy projects utilize these transformers. Solar farms and wind parks produce high voltage. These units tip it down for the grid. The 1000kva to 1500kva dimensions are common right here. They deal with the variable power flow reliably.

Mining procedures depend upon their toughness. Dust, resonance, extreme conditions are typical. The oil-immersed layout shields internal components. It insulates well and manages heat. Systems like the 500kva and 630kva are regular choices underground or at handling plants.

These transformers connect directly to medium voltage lines. Common inputs are 11kV, 22kV, or 33kV. Outcomes are normally 400V or 415V for neighborhood usage. They are developed solid for outdoor installation. Weatherproof tanks secure them from rainfall and sun. Safety and security functions are typical. They fulfill all necessary electrical guidelines. Options consist of different faucet changers for voltage control. Temperature evaluates help check efficiency. They are important equipment for significant electrical energy distribution.

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

Here are 5 common questions about our 400kVA, 500kVA, 630kVA, and 1500kVA 3-Phase Oil-Immersed Distribution Transformers:

What are these transformers used for? These transformers step down high voltage electricity from the power grid. They supply safer, usable lower voltage power for factories, large buildings, hospitals, and commercial complexes. They handle significant power loads reliably.

Where are they installed? They are built for outdoor use. You find them on concrete pads or platforms near the buildings they serve. They need good ventilation. Keep them away from flammable materials. They withstand weather conditions well.

What makes them reliable? Mineral oil inside cools the core and windings. This oil also provides strong electrical insulation. The robust steel tank protects internal parts. Quality materials and careful construction ensure long service life under heavy use. They offer stable voltage output.

What installation space is needed? You need enough space around the transformer for safe operation and future maintenance. Follow local electrical codes precisely.
