50KVA 11kv Suitable for High Temperature Three-phase Oil-immersed Outdoor Transformer

Overview of 50KVA 11kv Suitable for High Temperature Three-phase Oil-immersed Outdoor 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 50KVA 11kv Suitable for High Temperature Three-phase Oil-immersed Outdoor 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 50KVA 11kv Suitable for High Temperature Three-phase Oil-immersed Outdoor Transformer

This transformer manages 50,000 volt-amperes (50KVA). It works with three-phase electric systems. Its high voltage side links to 11,000 volt (11kV) high-voltage line. The low voltage side usually outputs 415 volts. This unit is developed for outside use. It holds up against weather condition like rain, wind, and sunlight.

The core and coils sit inside a strong steel tank. This storage tank is loaded with unique shielding oil. The oil cools down the transformer. It likewise supplies essential electrical insulation. This design is referred to as “oil-immersed”. The transformer is particularly produced warm places. It operates dependably in high ambient temperature levels.

Its insulation system uses high-temperature products. These materials withstand warmth destruction. The oil itself is chosen for remarkable thermal stability. This avoids malfunction even during expanded warm front. The transformer includes a larger radiator surface area. This enables better warm dissipation from the oil. Cooling fins might likewise be included. This keeps inner temperatures risk-free.

The storage tank is robustly secured. It prevents dampness and air from entering. Dampness damages the oil and insulation. The device includes a conservator tank. This conservator holds added oil. It lets the oil broaden and get safely with temperature modifications. A silica gel breather secures the oil. It dries any air entering the conservator.

The transformer has bushings for cable connections. These bushings are rated for 11kV on the high voltage side. They are porcelain or polymer. They are developed for outside contamination. Rise arresters are suggested. They protect versus lightning strikes and voltage spikes. The unit includes an oil level indication. This reveals the oil amount within. A pressure alleviation gadget is fitted. It airs vent excess stress safely.

Applications of 50KVA 11kv Suitable for High Temperature Three-phase Oil-immersed Outdoor Transformer

This 50KVA 11kV transformer is developed tough for demanding outdoor usage. It deals with heats accurately. The three-phase oil-immersed layout is essential. The oil successfully cools the core and windings also in hot problems. This prevents getting too hot and guarantees secure performance. The durable storage tank shields the interior components from climate. Rain, dust, and wind will not create troubles. The strong construction stands up to deterioration and physical damage. This transformer is developed for lengthy life span with very little maintenance.

It suits many applications requiring dependable power outdoors. Industrial sites like manufacturing facilities and plants use it usually. It powers machinery, lights, and control systems accurately. Construction tasks find it valuable for short-lived website power. It gives important electrical power for devices and website offices. Remote locations benefit significantly. Farms, mines, and telecommunications towers depend upon its consistent power distribution. Water pumping terminals and watering systems count on it too. It maintains important facilities running efficiently.

The 11kV rating makes it best for circulation networks. It tips down voltage securely for neighborhood usage. This transformer attaches easily to common medium-voltage lines. Its high-temperature capacity is a major benefit. It operates well in warm environments or near heat resources. This stays clear of pricey closures or derating. The oil insulation provides excellent dielectric stamina. This makes certain secure procedure and electrical seclusion. Basic installment and tried and tested reliability make it a functional selection. Users get reliable power where it’s required most.

5 FAQs of 50KVA 11kv Suitable for High Temperature Three-phase Oil-immersed Outdoor Transformer

This transformer handles high heat. It works outside. It powers industrial sites well. People often ask these questions.

What exactly is this transformer for? It steps down 11kV power. It supplies factories or large buildings. It works in hot places other units fail.

How hot can it safely run? Its rated ambient temperature reaches 55°C. Special oil and materials handle this heat. Normal transformers often max out at lower temperatures.

How does it cool down outside? It uses radiators. Oil circulates naturally. Heat dissipates into the air. This natural cooling works reliably even when it’s very hot. Fans are not needed.

Does the high heat mean more maintenance? Actually, no. Its robust design minimizes extra work. Check oil levels regularly. Inspect bushings and connections. Standard checks are usually enough. The construction handles the thermal stress.

Is it safe outdoors? Yes, it’s built for harsh conditions. The tank is weatherproof. It resists corrosion. Protection features guard against surges and faults. It meets outdoor safety standards.
