400kva 125kva Transformer High Quality Outdoor 100kva 500kva Oil Immersed Electric Power Transformer

Overview of 400kva 125kva Transformer High Quality Outdoor 100kva 500kva Oil Immersed Electric Power 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 400kva 125kva Transformer High Quality Outdoor 100kva 500kva Oil Immersed Electric Power 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.

Specifications of 400kva 125kva Transformer High Quality Outdoor 100kva 500kva Oil Immersed Electric Power Transformer

This transformer changes electricity voltage levels. It handles power safely and efficiently. We build it for outdoor use. Tough weather conditions won’t damage it. The transformer core sits inside a strong steel tank. Special insulating oil fills this tank. The oil cools the transformer parts. It also provides excellent electrical insulation. This design prevents overheating during continuous operation.

You get reliable power transfer. The oil-immersed construction ensures long service life. We make these transformers in standard power ratings. Common sizes include 100kVA, 125kVA, 400kVA, and 500kVA. Higher kVA numbers mean the transformer handles more power. Each unit meets strict industry standards for performance and safety.

The outer tank protects everything inside. It resists corrosion effectively. This is vital for outdoor installations. Think substations, industrial sites, or utility poles. Installation is straightforward. The transformer connects directly to power lines. Regular maintenance checks are simple. Just monitor the oil level and condition periodically.

These transformers work dependably year-round. Harsh sun, heavy rain, or wind won’t stop them. They manage varying electrical loads smoothly. Sudden power demands won’t cause problems. Efficiency is high. Energy losses are kept very low. This saves money over the transformer’s lifetime. Choose the kVA size matching your specific power needs. Our units deliver consistent, stable voltage output. They are a smart choice for demanding electrical distribution tasks.

Applications of 400kva 125kva Transformer High Quality Outdoor 100kva 500kva Oil Immersed Electric Power Transformer

These transformers move electricity safely. They step voltage up or down. This happens between power sources and places needing electricity. They work outdoors. They handle tough weather. Rain, wind, heat, cold don’t stop them. The oil inside is key. It cools the transformer. It also insulates the internal parts. This design makes them last long. It also makes them reliable.

The 125kVA unit suits smaller needs. Think small farms. Think remote telecom sites. Think small workshops. It powers essential equipment reliably. The 100kVA size is similar. It fits places needing moderate power. Maybe a large water pump station. Maybe a cluster of street lights.

The 400kVA transformer handles bigger loads. It fits factories well. It powers sections of machinery. It works for large commercial buildings too. Think shopping centers. Think hospitals needing backup power. The 500kVA unit is the strongest here. It powers large industrial processes. It supports whole sections of a power grid. It feeds substations in towns or industrial parks.

All these sizes share important features. They mount easily. They go on strong pads or poles. Their sturdy tanks protect the core and windings. The oil needs checking sometimes. Maintenance is straightforward. They run quietly. They operate efficiently. This saves energy costs. They are built tough. They handle daily electrical demands. They provide stable voltage. This keeps equipment running smoothly. They are vital for bringing power where it’s needed outside. They keep lights on, machines moving, and communities connected.

5 FAQs of 400kva 125kva Transformer High Quality Outdoor 100kva 500kva Oil Immersed Electric Power Transformer

Here are 5 common questions about our high quality outdoor oil immersed power transformers (125kVA to 500kVA):

What is this transformer used for? This transformer steps down high voltage electricity from power lines. It makes the voltage safe for use in factories, buildings, farms, or other places needing large amounts of power. It handles voltages between 11kV and 33kV down to 400V or 230V.

What makes it high quality? We use top grade materials. The core uses cold rolled grain oriented silicon steel. This reduces energy loss. High purity mineral oil cools and insulates the windings. Strong radiators keep oil temperature stable. Porcelain bushings provide reliable connections. Robust steel tanks protect everything outdoors.

Where can I install it? This transformer is built for outdoor use. It withstands rain, sun, wind, dust. Install it on concrete pads or plinths near your facility. Ensure good air flow around the radiators. Keep the area clear for safety and maintenance access. It works well in industrial zones or rural areas.

How does it stay cool? Mineral oil inside the tank absorbs heat from the core and windings. The heated oil rises naturally. It flows into external radiator banks. Air passes over the radiators, cooling the oil. The cooled oil sinks back down into the tank. This natural oil circulation provides effective cooling without fans.

Is it safe? Safety is critical. The tank is sealed tight to prevent oil leaks. We include features like a Buchholz relay. This relay detects internal faults and shuts the transformer down fast. An oil conservator allows for oil expansion and contraction. We follow strict international safety standards like IEC. Regular testing ensures reliability.
