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.

​In modern industrial automation, Variable Frequency Drives (VFDs) play a crucial role in controlling the speed and torque of AC motors, greatly improving energy efficiency and process flexibility.

In 2024, the world's major photovoltaic module-demanding countries generally encountered challenges such as weak economic performance, limited grid absorption capacity and tariff barriers, causing the photovoltaic market to enter a stage of slowing growth from that year.

The term "solar photovoltaic" has become familiar to many people today. What we commonly refer to as solar power generation is actually solar photovoltaic power generation, or "photovoltaic" for short. Photovoltaic power generation is a technology that uses the photovoltaic effect at the interface of semiconductors to directly convert sunlight into electrical energy.
