Electric Transformers Low Loss Three Phase Oil Immersed Distribution Power Transformer 20kva-5MVA

Overview of Electric Transformers Low Loss Three Phase Oil Immersed Distribution Power Transformer 20kva-5MVA

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 Electric Transformers Low Loss Three Phase Oil Immersed Distribution Power Transformer 20kva-5MVA

• 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 Electric Transformers Low Loss Three Phase Oil Immersed Distribution Power Transformer 20kva-5MVA

Here are five common questions about our low loss three phase oil immersed distribution power transformers (20kva-5MVA):

What makes this transformer “low loss”?
Our design significantly cuts down wasted energy. We use top quality grain-oriented silicon steel for the core. This reduces no-load loss. No-load loss happens when the transformer is plugged in but not powering equipment. We also optimize the windings. This lowers load loss. Load loss occurs during actual power delivery. Lower losses mean lower electricity bills over the transformer’s life.

What capacity range do these transformers cover?
We offer these transformers from 20 kilovolt-amperes (kVA) up to 5 megavolt-amperes (MVA). This range suits many distribution needs. Common uses include powering factories, commercial buildings, housing complexes, and renewable energy connection points. Tell us your specific voltage and power requirements. We find the right size unit for you.

How is this transformer installed?
Installation needs careful planning. The transformer arrives filled with insulating oil. It is heavy. Ensure your site has a strong, level foundation. Proper lifting equipment is essential. Connect the high voltage and low voltage terminals correctly. Follow all safety codes. Qualified electrical personnel must handle installation and commissioning. We provide detailed installation manuals.

What maintenance is required?
Regular checks keep the transformer reliable. Visually inspect the tank for leaks. Monitor the oil level using the gauge. Check the oil temperature. Sample the insulating oil periodically. Lab analysis finds moisture or breakdown products. Clean the radiators to prevent overheating. Keep the area around the transformer clear. Follow the maintenance schedule in the manual. Major internal work needs specialists.

Are these transformers safe?
Safety is critical. The robust steel tank protects the core and windings. The insulating oil cools the unit. It also prevents electrical arcing. Units include a conservator tank. This allows oil to expand and contract safely. A breather stops moisture entering the oil. Pressure relief devices guard against internal faults. Buchholz relays detect gas from internal problems. They trigger an alarm or shutdown. Always follow electrical safety procedures.
