11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed Power Transformer

Overview of 11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed Power 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 11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed Power 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.

5 FAQs of 11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed Power Transformer

Here are 5 common questions about 11, 13, 14 MVA (12500kVA, 13000kVA) oil-immersed power transformers:

What capacity range do these transformers cover?
These transformers handle large power loads. They come in 11 MVA (11,000 kVA), 13 MVA (13,000 kVA), and 14 MVA (14,000 kVA) sizes. This covers needs like 12500 kVA and 13000 kVA. They move significant electricity for industrial sites or substations.

What voltages do they handle?
They manage high transmission and distribution voltages. Primary voltages are often 33 kV, 66 kV, or 110 kV. Secondary voltages are commonly 6.6 kV, 11 kV, or 33 kV. The exact voltages are custom ordered for the specific project requirements.

How does the oil cooling work?
The transformer core and windings sit inside a tank filled with special insulating oil. This oil absorbs heat generated during operation. The heated oil naturally rises. It flows through radiator banks or cooling fins attached to the tank. Air cools the oil there. The cooled oil sinks back down. This cycle keeps the transformer at a safe operating temperature.

Where are these transformers typically used?
You find them in demanding electrical networks. They are common in primary substations receiving power from the grid. Large factories, processing plants, and heavy industries use them. Mines and large commercial complexes also rely on these units. They step down high incoming voltage to usable levels for the facility.

What standards ensure safety and performance?
They meet strict international and local rules. Key standards include IEC 60076 and IEEE C57. These cover design, testing, safety, and efficiency. Manufacturers follow these standards. This ensures reliable, safe operation over a long lifespan.
