10kV 35kv MV&HV Distribution Transformer Oil Immersed Type 3 Phase 440v 480v Step 3 MVA 1000kva 800 Kva Electrical Transformer

Overview of 10kV 35kv MV&HV Distribution Transformer Oil Immersed Type 3 Phase 440v 480v Step 3 MVA 1000kva 800 Kva Electrical 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 10kV 35kv MV&HV Distribution Transformer Oil Immersed Type 3 Phase 440v 480v Step 3 MVA 1000kva 800 Kva Electrical 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.
