• Pendinginan yang Efektif: Oli isolasi secara efisien menyerap panas dari inti dan belitan serta memindahkannya ke sirip radiator, memungkinkan sirkulasi alami atau paksa dan kapasitas kelebihan beban yang lebih tinggi.
• Isolasi Unggul: Minyak memberikan kekuatan dielektrik yang jauh lebih baik dibandingkan udara, memungkinkan desain yang lebih kompak untuk peringkat tegangan tertentu dan melindungi terhadap korsleting.
• Konstruksi Kuat: Dirancang untuk jangka panjang, operasi yang andal (sering 25-30 bertahun-tahun) di lingkungan luar ruangan yang keras.
• Kapasitas Kelebihan Beban: Dapat menangani kelebihan daya sementara dengan lebih baik daripada transformator tipe kering karena massa termal dan sifat pendinginan oli.
• Sistem Proteksi: Dilengkapi dengan tangki konservator (untuk memungkinkan ekspansi minyak), istirahat (untuk menyerap kelembapan dari udara), dan relay pelindung (Relai Buchholz) untuk deteksi kesalahan internal.
• Hemat Biaya: Umumnya lebih ekonomis untuk aplikasi daya tinggi dibandingkan trafo tipe kering.

These transformers step down 20kV circulation voltage to functional 400V or 415V degrees. They are crucial devices for delivering power securely to factories, buildings, and large centers. The core and windings sit inside a durable steel tank loaded with specialized insulating oil. This oil cools the transformer and stops electric malfunction.

Criterion key voltage is 20,000 volts. Additional voltage is normally 400 volts or 415 volts. The frequency is 50Hz or 60Hz, depending upon regional needs. Cooling down relies upon the ONAN technique. This implies the oil circulates normally inside the storage tank. Warmth transfers to the air via outside cooling fins or radiators.

Efficiency is important. Lots losses and no-load losses are lessened. Greater kVA models normally accomplish far better efficiency numbers. Expect performance ratings between 97% Dan 99% for these devices. Actual efficiency depends upon the details tons account. Sound levels are maintained reduced. Sound pressure is generally below 55 decibels determined at 1 meter.

Physical dimension and weight boost considerably with kVA rating. A 50kVA unit might evaluate around 500kg. A 500kVA unit can exceed 3000kg. All transformers consist of important security devices. Stress safety valve protect against interior mistakes. Temperature level indications check oil and winding warmth degrees. Transformers above 250kVA generally include Buchholz relays. These identify gas buildup from interior arcing.

Installation needs a strong, degree concrete pad. Correct grounding is obligatory. Regular oil screening and upkeep guarantee lengthy service life. These transformers are developed for trustworthy procedure. They manage constant task under differing tons conditions. Environmental management fulfills IP55 requirements. This defend against dust and water jets. Efficiency abides by pertinent IEC criteria.

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

These oil-filled transformers step down 20kV power for day-to-day usage. Their durable design takes care of requiring atmospheres accurately. Various sizes fit specific power demands.

The smaller sized 50kVA and 100kVA units function well for stores, small factories, or farms. They power necessary illumination, tools, and equipment without taking much space. Assume small workshops or water pumps. The 150kVA size supplies a little bit a lot more capability. It matches bigger retail areas, bigger workshops, or little business buildings requiring regular power.

Moving up, the 200kVA and 250kVA transformers take care of considerable lots. They prevail in medium manufacturing facilities, bigger commercial facilities, or institutions. They accurately run multiple machines, cooling and heating systems, and lights circuits. The 300kVA system provides a lot more power. It fits well in producing plants, healthcare facilities needing backup, or multi-story office complex. It keeps crucial operations running efficiently.

For sturdy needs, the 400kVA and 450kVA transformers provide serious power. They sustain big commercial centers, large hospitals, or major building and construction sites. These units handle heavy machinery, big motors, and intricate electric systems without stress. The biggest 500kVA transformer tackles the most significant tasks. It powers big factories, major information centers, or significant mining operations. It’s also used in neighborhood substations distributing power to areas or commercial parks.

All these transformers utilize oil for cooling and insulation. This makes them tough and long-lasting, especially outdoors or in severe conditions. They form the reliable backbone of power distribution. They securely convert high voltage right into useful power for many applications.

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

What does this transformer do?
It changes high voltage electricity to lower voltage. Factories, buildings, and power grids use it. It safely powers equipment needing less voltage.

Where is this transformer usually installed?
You find these units outdoors. Substations, industrial plants, and large building sites use them. They handle heavy power loads reliably. They are built tough for outside conditions.

Is it safe?
Ya, safety is a priority. The transformer sits inside a strong steel tank filled with special oil. The oil cools it down and insulates the internal parts. This design greatly lowers fire risk. It meets strict safety rules.

How much maintenance does it need?
Very little. These transformers are known for being reliable. You need to check the oil level and quality sometimes. Look for leaks. Keep the outside clean. A basic check once or twice a year is often enough. This keeps it running well for years.

Why choose oil-immersed over dry-type?
Oil types handle more power in a smaller size. They cost less for big power jobs like 50KVA to 500KVA. The oil cools better. This makes them more efficient under heavy use. They last longer in demanding outdoor spots. They are the standard choice for heavy distribution work.
