Overview of 20kv 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Oil Immersed Electrical Power 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 20kv 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Oil Immersed Electrical Power 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.

Cooling relies upon all-natural oil blood circulation and air. This is the ONAN cooling approach. Radiators are bonded to the storage tank. They enhance the cooling area. This keeps the transformer within risk-free operating temperature levels.

The transformer fulfills international requirements. These include IEC 60076 and appropriate national codes. This ensures safety and security and performance consistency. Losses are maximized for efficiency. The insusceptibility voltage is meticulously regulated. This protects versus short-circuit stress and anxieties.

The system includes crucial security tools. A pressure alleviation gadget prevents container tear. An oil degree gauge shows the oil quantity. A thermostat keeps track of the oil temperature level. Larger units typically have a Buchholz relay. This identifies internal gas development from faults.

Setup alternatives are adaptable. The transformer can be pole-mounted. It can likewise sit on a concrete pad. The container features lifting lugs for easy handling. Drain pipes shutoffs allow oil sampling and adjustments.

Building and construction concentrates on lengthy service life. The storage tank resists deterioration. Gaskets make certain a tight seal. This avoids oil leakages and wetness access. Maintenance needs are reduced. Normal oil checks and aesthetic examinations are essential.

Applications of 20kv 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Oil Immersed Electrical Power Distribution Transformer

Oil-immersed electrical power circulation transformers take care of voltages as much as 20kV. They are available in sizes from 50kVA to 500kVA. These systems tip down high voltage power for day-to-day usage. They are common in position requiring reliable power distribution.

Factories use these transformers for heavy machinery. They power motors and production line. A 150kVA model matches medium manufacturing facilities. Larger plants might select 300kVA or 400kVA devices. Building and construction websites depend on them also. They supply short-lived power for devices and lights. A 100kVA transformer typically functions right here.

Commercial buildings depend upon these transformers. Shopping malls utilize 200kVA or 250kVA kinds. They run escalators and a/c. Medical facilities select 500kVA transformers for essential systems. They keep life-saving equipment running.

Rural electrification tasks set up these transformers. They bring power to towns. A 50kVA device serves little areas. Bigger communities need 450kVA transformers.

Oil cooling makes these transformers long lasting. They manage heat well throughout lengthy procedures. The oil likewise protects inner components. This protects against electrical failures. Maintenance is uncomplicated. Technicians check oil degrees and links regularly.

These transformers function outdoors. They stand up to rain and wind. Substations put them on concrete pads. Farms utilize them for irrigation pumps. A 100kVA design powers water supply.

Energies release them throughout power grids. They minimize voltage for neighborhood supply. A 200kVA transformer feeds a number of roads. Cities use multiple 300kVA units for broader coverage.

Oil-immersed transformers are economical. They last over 25 years with appropriate treatment. Industries choose them for consistent performance. They operate silently and need little space.

5 FAQs of 20kv 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Oil Immersed Electrical Power Distribution Transformer

What exactly is this transformer?
This is an oil-filled power distribution transformer. It handles high voltage electricity at 20,000 volts. It steps down this voltage for safe use in factories, buildings, or towns. We offer sizes from 50kVA to 500kVA.

Is it safe?
Yes. It meets strict international safety rules (like IEC 60076). The special oil inside does two jobs. It cools the transformer. It also insulates the electrical parts. The strong steel tank protects everything inside. Safety features like pressure relief valves are standard.

Where can I put it?
You can install it indoors or outdoors. For outdoor use, it needs a solid concrete pad. Keep enough space around it for air to flow. This helps it stay cool. Make sure the area is clean and dry. Protect it from floods or heavy pollution.

How long will it last?
With proper care, it lasts over 25 years. The key is regular, simple checks. Look at the oil level gauge often. Keep the outside clean. Watch for leaks. Listen for unusual noises. Check the temperature. We provide a full maintenance guide.

Can it handle overloads?
It handles short overloads well. The oil cooling helps with this. But don’t run it overloaded for long periods. This causes too much heat. Too much heat damages the insulation. This shortens the transformer’s life. Always size it correctly for your normal load.
