35kV SYTZZ on-load voltage regulation tap changer

The series are suitable for oil-insulated power transformers with 50HZ, the highest voltage for equipment is 40.5kV, the rated through-current is 400A or less, and the D/Y on the high-voltage side is connected to the central span voltage regulation. It can be matched with Jinli's JLk-103 or JLk-716A controller, and the standard cable length is 30 meters.

product details

Model

For example: SYJZZ 200/35-9 is the triple-phase on-load terminal voltage regulation and adopts a resistive transition resistor. It is directly switched and is rated at 200A as well rated voltage 35kV, and the it has 9 taps.

Advantage

It has reliable structure and high stability, and can stabilize or regulate the voltage of the load center through matching Jinli's supporting controller, improves the voltage quality, improves the system power factor, and reduces reactive power consumption.

1. Its structure design is reasonable and the stable.

2. It can be matched with our company's supporting controller, which can stabilize or adjust the voltage of the load center, improve the voltage quality, improve the power factor of the system, and reduce reactive power consumption.
