In tunnel construction, mud pumps are indispensable equipment, but their energy consumption has always been a focus of attention. To achieve energy conservation and efficiency, a ZK frequency converter (ZK300 380V/75kW) was used for remote control of the tunnel mud pump, yielding significant results.

Electric cargo ships equipped with ZK300 series high-performance engineering frequency converters have been in operation for several days. Their adoption of new straight-wing propulsion technology and a diesel-electric hybrid power system marks a new stage in shipping: "green, efficient, and intelligent."

The types of fans include negative pressure fans, circulating fans, centrifugal fans, Roots blowers, boiler induced draft fans, and copper furnace blowers.

The wire and cable industry is currently moving towards greater technological development, including product diversification and automation. Powered wire feeding frames are very common in the industry. Based on their style, powered wire feeding frames can be divided into vertical wire feeding frames and horizontal wire feeding frames. Both are wire feeding devices, differing only in structure. In the wire feeding process, frequency converters have become indispensable equipment. Frequency converters can control the speed of the motor to achieve the wire feeding speed, thereby improving the process level and production efficiency, ensuring process quality, and maximizing profits.

A frequency converter is a control device that uses the switching action of power semiconductor devices to convert power frequency power into electrical energy of another frequency. It can realize functions such as soft starting of AC asynchronous motor, variable frequency speed regulation, improved operating accuracy, power factor change, and overcurrent/overvoltage/overload protection.
