Customized 12500KVA 20000KVA Electric Transformer 35KV 10.5KV Pure Copper Oil Immersed Three Phase 10KV Input Voltage 380V

Overview of Customized 12500KVA 20000KVA Electric Transformer 35KV 10.5KV Pure Copper Oil Immersed Three Phase 10KV Input Voltage 380V

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 Customized 12500KVA 20000KVA Electric Transformer 35KV 10.5KV Pure Copper Oil Immersed Three Phase 10KV Input Voltage 380V

• 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.

Applications of Customized 12500KVA 20000KVA Electric Transformer 35KV 10.5KV Pure Copper Oil Immersed Three Phase 10KV Input Voltage 380V

These large capacity transformers handle serious power needs. They step down high voltage electricity to usable levels. The 35KV or 10.5KV input suits many industrial grids. The output gives 380V for heavy machinery. Pure copper windings are key. Copper conducts electricity better than aluminum. This means less energy wasted as heat. Less heat loss improves efficiency. Better efficiency saves money over time. Pure copper also handles overloads better. It lasts longer under tough conditions.

These transformers are built for demanding places. Factories use them constantly. They power large motors, furnaces, and assembly lines. Mining operations rely on them underground. They run crushers, conveyors, and ventilation systems. Power plants need them for auxiliary systems. Water treatment facilities depend on their steady output. Oil refineries and chemical plants use them too. Any site with massive power demand is a candidate.

The oil-immersed design is crucial. Oil cools the transformer core and windings effectively. This cooling prevents overheating during peak loads. Overheating damages equipment. Oil insulation allows a more compact build. This saves space in crowded substations. The robust tank protects internal parts. It withstands harsh weather and industrial environments. Routine oil testing ensures long-term reliability.

The three-phase design is standard for industrial power. It delivers balanced, efficient energy. The 10KV input voltage is common. It connects directly to many regional distribution networks. The 380V output powers standard industrial equipment. This avoids extra conversion steps. Fewer steps mean lower costs. Fewer steps also mean fewer points of failure.

Customization is possible. Size and ratings fit specific site requirements. Exact voltage ratios can be adjusted. Cooling options might be tailored. Mounting configurations suit different substation layouts. This flexibility ensures optimal integration. Proper integration maximizes performance. Reliable performance keeps operations running smoothly. These transformers are workhorses for heavy industry.
