Vertical electric cage type tap changer-star angle conversion

This series of switches is composed of an electric transmission mechanism, a switch body, and an electric controller. It is designed to be used in oil-immersed transformers with a maximum equipment voltage of 126 kV or lower and a rated current of 1250A or lower. The tap switching can be operated electrically or manually when the transformer is not in the excitation state. These switches are intended to be used in conjunction with our company’s electric controller JLK-718A.

This tap changer can only be operated when the transformer is de-energized.

Designed specifically for high voltage power transformers, this tap changer features a unique vertical design for easy installation and maintenance. The vertical orientation also allows for more compact and efficient use of space within the transformer, making it an ideal solution for densely populated substations.

The star-to-pole conversion capability of the tap changer can achieve seamless conversion between different voltage levels, providing greater flexibility for power distribution and ensuring stable and reliable power supply. This feature is particularly useful in systems with fluctuating power demand, as it allows for quick, precise adjustments to match required voltage levels.

In addition to innovative design and functionality, our vertical electric cage tap-changers are designed to withstand the harshest operating conditions. Its sturdy construction and high-quality materials ensure long-lasting performance, even in the most demanding environments.
