Overview of Best 6kv – 33kv 400v 500kva 50kva 100kva 50kva 400kva Power Distribution Transformer Oil Immersed 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 Best 6kv – 33kv 400v 500kva 50kva 100kva 50kva 400kva Power Distribution Transformer Oil Immersed 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.

These transformers move electricity efficiently in power networks. They step down high voltages like 6kV, 10kV, 11kV, 20kV, 33kV to a standard low voltage of 400V. This powers factories, buildings, towns. Various capacities exist: 50kVA, 100kVA, 400kVA, 500kVA. Choose the size matching your load needs.

The core uses high-grade silicon steel. Copper or aluminum windings carry the current. These parts sit inside a sturdy steel tank. The tank is filled with special insulating oil. This oil cools the transformer. It also provides electrical insulation. This design is called Oil-Immersed, Naturally Cooled (ONAN).

These transformers are built tough. They handle outdoor conditions well. Radiators attached to the tank help dissipate heat. A conservator tank holds extra oil. This allows for oil expansion. A Buchholz relay detects internal faults. Pressure relief devices protect against overpressure. These features ensure safety and long life.

They meet strict international standards like IEC 60076. This guarantees performance and safety. The impedance voltage is carefully controlled. This ensures stable operation during faults. The transformers offer different connection groups. Examples are Dyn11 or Yyn0. This provides flexibility for your network setup.

Performance is key. Low no-load losses save energy. Low load losses save more energy under operation. The sound level is kept low. This minimizes noise pollution. The efficiency is high across the load range. This reduces operating costs significantly. The insulation system is robust. It withstands electrical stresses reliably. Works reliably for many years with proper care.

Applications of Best 6kv – 33kv 400v 500kva 50kva 100kva 50kva 400kva Power Distribution Transformer Oil Immersed Transformer

These oil-filled transformers handle power distribution. They step down high voltage electricity. The input range is 6kV to 33kV. They output at common low voltages like 400V. Available sizes include 50kVA, 100kVA, 400kVA, and 500kVA. This flexibility meets different power needs.

Factories use them extensively. Manufacturing plants need reliable power. These transformers deliver it. They supply heavy machinery, production lines, lighting systems. Mines and oil fields rely on them too. Harsh environments demand tough equipment. The oil-immersed design provides durability.

Commercial buildings depend on these transformers. Shopping malls, hospitals, office towers need steady electricity. They power HVAC systems, elevators, computers, lighting. The transformer ensures stable voltage levels. This protects sensitive equipment.

Renewable energy projects integrate them. Solar farms and wind parks generate power. This power often needs transformation. The transformers connect these sources to the grid. They adjust the voltage for efficient transmission.

The design is simple and robust. A core and coils sit inside a metal tank. The tank is filled with special insulating oil. This oil cools the transformer. It also insulates the internal parts. This oil extends the transformer’s life.

These transformers are built for safety. They feature pressure relief devices. Temperature gauges monitor operation. Oil level indicators are standard. They meet international safety certifications. This ensures reliable performance over years. Routine maintenance is straightforward. This keeps downtime low.

5 FAQs of Best 6kv – 33kv 400v 500kva 50kva 100kva 50kva 400kva Power Distribution Transformer Oil Immersed Transformer

Here are 5 common questions about our 6kV-33kV oil-immersed power distribution transformers (50kVA, 100kVA, 400kVA, 500kVA):

What voltages do these transformers handle?
These transformers step down electricity. The primary side accepts input voltages between 6,000 volts and 33,000 volts. The secondary side consistently outputs 400 volts. This fits standard industrial and commercial power distribution needs.

Why use oil inside?
The transformer core and windings sit inside a tank filled with special insulating oil. This oil does two main jobs. It cools the transformer effectively during operation. It also provides crucial electrical insulation. This combination ensures stable performance and long life.

How do I pick the right kVA size?
Choose the transformer capacity (50kVA, 100kVA, 400kVA, 500kVA) based on your actual load requirement. You need to know the total power (kVA or kW) your equipment uses. Factor in possible future expansion. Getting a transformer too small causes overload and damage. A transformer too large wastes money and energy.

Can I install this myself?
No. Installing these transformers requires trained professionals. They handle high voltage connections safely. Proper site preparation is essential. This includes a solid foundation and clearances for ventilation and safety. Only qualified electricians should do the wiring and commissioning.

What maintenance is needed?
Regular checks are vital. Monitor the oil level inside the tank through the sight glass. Look for any leaks around the tank, bushings, or radiators. Schedule periodic testing of the oil quality. This checks its insulating strength and checks for problems inside. Keep the exterior clean for good cooling.
