Wenzhou Qiaonasen Electrical Equipment Co., Ltd. recently announced that its new distribution cabinet using self-developed modular assembly technology and eddy current protection mechanism has been successfully applied in many new energy grid connection projects. 

This batch of equipment has been specifically optimized for the special environment of high temperature, humidity and salt fog in coastal areas, greatly improving the stability and reliability of the power system.
In recent years, with the continuous growth of installed green energy capacity in the Wenzhou area, it is expected to reach 10.035.5 million kW by the end of the 14th Five-Year Plan. The rapid development of new energy projects places greater demands on electrical equipment, and Qiaonasen Electrical Equipment's innovative products meet this market demand.

01 Industry context

Currently, China is actively promoting the construction of new energy systems in line with the goals of “peaking carbon emissions and carbon neutrality.” Wenzhou Electric Power Supply Company carefully took on the main line of building a diversified integrated highly elastic power grid and a power grid that is not afraid of typhoons, combined geographical features and advantages to build a new power grid with the characteristics of a "full scenario of mountain cities, sea islands, scenery, scenery, water and nuclear

On the supply side, Wenzhou Electric Supply Company GuoGrid has been making efforts to promote the development of clean energy, including the completion and commissioning of the 220kV Yuhai Wind Power Transmission Project in Cangnan County, and the construction of a 550MW photovoltaic power transmission project in the Ofei Reclamation Area.

These large power projects urgently require reliable and efficient power distribution equipment, especially in coastal areas where the equipment must be able to withstand harsh environmental conditions of high temperature, high humidity and high salt spray.

02  TECHNOLOGICAL

The new distribution cabinet introduced by Qiaonasen Electrical Equipment this time uses a number of innovative technologies. This modular enclosure assembly includes a mounting plate and symmetrically mounted side panel assemblies, simplifying the enclosure assembly process and increasing operational efficiency.

The side panel assembly includes a symmetrically located left panel assembly and a right panel assembly, which can be secured to the left and right sides of the switchgear cabinet frame, respectively. This design is not only convenient for production and installation, but also facilitates subsequent modification and upgrading of switchgear functional modules, which greatly improves the applicability and scalability of the equipment.

More importantly, the company has also developed switchgears with anti-vortex mechanisms, including first and second longitudinal beams arranged parallel in the vertical direction and a support frame located between them. The support frame is made of stainless steel, a non-magnetic material that effectively cuts the closed metal loop and prevents eddy currents from occurring in the switchgear.

03 Future prospects

Looking into the future, Qiaonasen Electrical Equipment will continue to increase investment in research and development and continuously produce more advanced and reliable power equipment products. The company plans to further expand its market share in new energy sources and provide greater support to the global green energy transformation.

The company's technical director said: “We will continue to follow the development trends of the electric power industry, continuously introduce innovations and breakthroughs to provide customers with better products and services. At the same time, we will actively expand the international market so that Chinese-made power equipment enters the world.”
