Oil Immersed Electrical Power Distribution Transformer 50KVA to 500KVA Three Phase 20KV

Overview of Oil Immersed Electrical Power Distribution Transformer 50KVA to 500KVA Three Phase 20KV

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 Oil Immersed Electrical Power Distribution Transformer 50KVA to 500KVA Three Phase 20KV

• 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.

Criterion primary voltage is 20,000 volts. Additional voltages are flexible. Typical choices are 400V, 480V, or others. We customize this to your particular demands. Regularity is generally 50Hz or 60Hz. Validate your local requirement.

ONAN cooling is the fundamental approach. This indicates Oil Natural Air Natural. The oil flows normally within. Heat dissipates from the storage tank surface area. Radiators increase the cooling area. They affix to the primary tank. Bigger systems could require followers. Followers offer additional cooling power. This is OFAN air conditioning.

The transformer includes necessary defense. An oil level gauge monitors the fluid. A pressure relief tool protects against overpressure. Thermometers track running temperature level. We add a silica gel breather. This keeps wetness out of the oil. Raising lugs are fitted for secure handling. Earthing terminals make certain correct grounding.

These devices work well in various places. They are common in plants. They supply manufacturing facilities and huge structures. Utilities mount them on distribution poles. They are trusted for substations. They run outdoors. They manage requiring environments. Normal upkeep is necessary. This ensures long life span. It additionally maintains safety and security criteria. The style prioritizes toughness and regular efficiency.

Applications of Oil Immersed Electrical Power Distribution Transformer 50KVA to 500KVA Three Phase 20KV

These oil-filled transformers manage power circulation for many organizations. They take high voltage electrical energy and tip it to usable degrees. Common sizes vary from 50KVA as much as 500KVA. They collaborate with three-phase power systems. The primary voltage score is generally 20 kilovolts.

Factories rely greatly on these devices. They power huge machines like electric motors, presses, and production line. The oil inside maintains the transformer cool under heavy commercial tons. This cooling is important for consistent operation. Storehouses and manufacturing plants use them extensively.

Energies install these transformers as well. They feed power to smaller sized substations or teams of structures. Think of service parks or shopping mall. The transformer sits inside a protective enclosure outdoors. It safely distributes power over its local area.

Building and construction sites frequently require temporary power. These transformers give it accurately. They deal with the dirt and variable climate condition usual on website. Mining procedures likewise depend upon their strength. Severe atmospheres demand resilient devices.

Industrial structures utilize them often. They supply power to workplace blocks, healthcare facilities, and institutions. The transformer actions down the voltage from the utility feed. After that it sends power throughout the structure facility. Dependability is crucial right here.

These transformers are developed for long life. The oil insulation and cooling down system work well together. They handle warm successfully during operation. This style stops overheating problems. Maintenance is relatively straightforward. Specialists check oil degrees and examination insulation resistance frequently. Proper treatment makes certain several years of service.

Backwoods benefit from their usage. They tip down voltage for farms and agricultural handling plants. Remote places need reputable power distribution. These transformers deliver that. They manage the ranges included.

5 FAQs of Oil Immersed Electrical Power Distribution Transformer 50KVA to 500KVA Three Phase 20KV

What does this transformer do?
It safely steps down high voltage electricity. It changes 20,000 volts to lower voltages. This lower voltage powers factories, buildings, or communities. It handles big loads from 50,000 VA to 500,000 VA.

Where is this transformer used?
You find it in industrial plants needing lots of power. It’s common in commercial buildings like malls. Utilities use it in neighborhood substations. Any place needing reliable three-phase power distribution uses it.

Why choose oil-immersed?
Oil cools the transformer. It stops overheating. Oil also insulates the internal parts. This design is tough. It handles heavy use for many years. It’s reliable for critical power needs.

What’s needed for installation?
A solid, level concrete pad is essential. Enough space around it is mandatory. This allows for safe operation and maintenance. Proper grounding is critical for safety. Skilled electricians must connect the high and low voltage cables correctly. Local electrical codes must be followed.
