Definitions and Characteristics:
Oil-Immersed: It means that the iron core and windings of the oil-immersed distribution transformers are immersed in insulating oil, and the oil plays a dual role of cooling and insulation.
Distribution Transformer: It is used to convert high-voltage electrical energy into low-voltage electrical energy for users' use.
Three-Phase: Usually, it means that the oil-immersed distribution has three independent windings and is applicable to three-phase alternating current systems.
Iron Core: It is usually made by laminating high-quality silicon steel sheets, featuring low loss and low noise.
Windings: The primary winding and the secondary winding are usually wound with copper wires, possessing excellent electrical conductivity and mechanical strength.
Insulating Oil: The inside of the transformer is filled with insulating oil. The oil not only plays a cooling role but also provides good insulation performance.
Oil Tank: The iron core and windings of the transformer are installed in the oil tank. The oil tank is usually made of steel plates and has good sealing performance.
Cooling System: Depending on the power level, oil-immersed transformers can adopt natural cooling, air cooling or forced oil circulation cooling methods.
Bushing: The high-voltage and low-voltage leads are led out through the bushing. The bushing has good insulation performance to ensure safe operation.
This oil-immersed distribution transformer is designed with features like low energy loss and high efficiency. Using copper coils and a sealed structure helps it use less electricity while providing reliable performance, which saves money on energy bills.
Yes, this oil-immersed distribution transformer usually comes with a warranty, which means if something goes wrong within a certain period, the manufacturer will repair or replace it without additional cost.
Proper installation of a oil-immersed distribution transformer is crucial to ensure safety and efficiency. If it's not installed correctly, it could lead to electrical failures or even accidents, so always use a qualified electrician for installation.
Absolutely! The manufacturer or supplier usually provides customer support. They can help with any issues or questions you might have regarding installation, maintenance, or troubleshooting.
