Applications of Three Phase 3150-3000-6300 10000 /24000 /25000 /20000 KVA 115KV/10KV/132KV Input 440V/380V/11KV Oil Immersed Power Transformer

This three-phase oil-immersed power transformer handles big jobs. It steps down high voltage electricity to safer, usable levels. Its main task is receiving power from the grid at very high voltages like 115kV, 132kV, or 10kV. It then transforms this power down to lower voltages like 11kV, 440V, or 380V. This makes the power suitable for factories, big buildings, and entire towns.

You find this transformer type in heavy industries. Steel mills, large chemical plants, and big mining operations need huge amounts of power. They use these transformers to get the right voltage for massive motors, furnaces, and processing equipment. Reliability is key here. The oil insulation helps manage heat and keeps things running smoothly.

Power utilities rely heavily on these units. They form the backbone of substations. These substations take power from long-distance transmission lines. The transformers lower the voltage for local distribution networks. This powers homes, businesses, and smaller industries across a wide area. The high capacity, like 10,000 KVA or 25,000 KVA, means one transformer can serve many customers.

Large infrastructure projects also use these transformers. Think major airports, seaports, or large hospital complexes. These places have huge, constant power demands. The transformer provides the stable, high-capacity supply they require. It ensures critical systems always have power.

The oil-immersed design offers proven durability. It handles high loads effectively. This transformer type is built tough for long-term service in demanding locations. It connects the high-voltage grid directly to the point where power is consumed on a large scale. Selecting the exact model depends on the required capacity and the specific input/output voltages needed for the site.
