SFSZL-40000/158 Transformer py-product-icon-1

This industrial transformer features three independent terminals. The high-voltage side receives power from the 158 kV high-voltage transmission grid. The medium-voltage side steps down the voltage to 38.5 kV, typically used for regional low-voltage networks or industrial power supply to large facilities. The low-voltage side further reduces the voltage to 27.5 kV, commonly employed for specific industrial heavy-duty loads, mining area power distribution, or specific rail transit systems.

S11-M Series Of Oil-Immersed Full-Sealed Distribution Transformer py-product-icon-1

The high voltage coil adopts continuous type or inner continuous type to improve the longitudinal capacitance distribution of the coil under impulse voltage. The coil adopts the oil-conducting circulation structure to reduce the temperature rise of the winding, and the design life of the product is 30 years. Hardness support in the coil, double dovetail pad support, upper and lower edge insulation is the pressure plate of the entire platform, high mechanical strength, strong ability to resist sudden short circuit. The coil and the insulating parts inside the coil become thicker with the circle, reducing partial discharge. Ensure that the main body is assembled as a whole, constant pressure is dried, the coil shrinks uniformly, and the screenshot is small, which effectively improves the electrical strength and short-circuit resistance of the transformer.
