Silica gel absorbs moisture inside the breather.

Bushings are porcelain or polymer. Bushings connect the high and low voltage cables. An oil level indicator shows the oil position. A pressure relief device prevents tank damage. This device vents if pressure gets too high. All transformers have lifting lugs. Lifting lugs make moving easier. Earthing terminals are standard. Terminals ensure safe grounding.

No-load losses and load losses meet efficiency standards. Loss values depend on the specific kVA rating. Higher kVA models weigh more. Weight increases significantly with capacity. The transformer withstands normal short circuits. The design includes safety margins. Units are tested rigorously before shipping. Tests confirm performance and safety.

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

These oil-immersed transformers handle 20kV primary voltage. They are vital for getting power where it’s needed safely. The 50kVA and 100kVA models suit smaller operations. 小さな工場を考えてみましょう, ワークショップ, or groups of shops. They step down voltage for machines and lighting reliably. They are compact and tough for these everyday jobs.

The 150kVA and 200kVA units serve bigger demands. They power larger commercial buildings like shopping centers or office blocks. Hospitals and schools often rely on these sizes too. They manage the constant power needs of many people and systems. Their oil cooling keeps them stable during long hours.

Need serious power? Look at the 250kVA and 300kVA transformers. Heavy industrial settings use them. Think production lines with big motors or large processing equipment. They deliver consistent voltage under heavy loads. Their robust build handles the tough factory environment.

最大のユニット, 400kVA, 450kVA, および500kVA, are for major projects. Big factories with intensive machinery need this capacity. They might feed entire sections of a plant. These transformers also work well in dedicated power substations. They serve as key distribution points for wider areas. Renewable energy sites, like solar farms, often use them to connect to the grid. Their high capacity and 20kV rating make them versatile power hubs. The oil insulation provides excellent cooling and electrical protection. This ensures long life and dependable operation. Choosing the right kVA size matches the specific power load requirement.

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

ここにあります 5 common questions about our 50kVA to 500kVA Oil Immersed Distribution Transformers (20kV):

これらの変圧器は実際には何をするのか?
They safely step down 20kV high voltage electricity to lower voltages suitable for factories, 建物, または近所. They handle power from 50,000 に 500,000 ボルトアンペア.

How do I pick the right size transformer?
Calculate your total electrical load. Add up the power needs of everything connected. Pick a transformer size larger than your calculated load. This gives room for future growth. Our team helps with sizing calculations.

Why do they use oil?
The oil inside is crucial. It insulates the internal parts. It also cools the transformer. The transformer gets hot during operation. The oil carries this heat away to the tank walls. これにより、変圧器の安全な動作が維持されます.

Where and how should I install one?
Install them outdoors. They need good air circulation. Mount them on strong concrete pads. Keep them away from walls or other equipment. 地域の電気規定に正確に従ってください. Proper grounding is essential for safety.

どのようなメンテナンスが必要か?
定期的にオイルレベルを確認してください. 漏れを探す. Keep the exterior clean. Inspect bushings and connections periodically. 数年ごとにオイルの品質をテストする. This finds any internal problems early. メーカーのメンテナンススケジュールに従ってください.
