Power fittings industry welcomes technological innovation, high-strength composite materials promote power grid upgrade

Recently, breakthrough progress has been made in the domestic power fittings field. Several leading companies have jointly developed high-strength corrosion-resistant fittings that have officially passed the certification of the State Grid Testing Center. The product uses nano-alumina reinforced epoxy resin composite material, combined with die-casting m process, which has increased the tensile strength of key parts such as strain clamps and suspension clamps to more than 800MPa, and the salt spray corrosion time has exceeded 3000 hours, far exceeding the requirements of GB/T 2314-2020 standard.

Industry analysis points that with the acceleration of the construction of ultra-high voltage AC/DC mixed grid, traditional forged cast iron fittings can hardly meet the needs of high load and low energy consumption This technological iteration will significantly improve the mechanical stability and environmental adaptability of transmission lines, especially suitable for extreme working conditions such as high altitude and strong wind areas.

In, the "14th Five-Year Plan" of State Grid clearly proposes that the intelligent fittings matching rate needs to be increased to more than 40%, promoting to increase investment in the research and development of integrated online monitoring sensor technology. Our company, as an ISO 9001 certified unit, has built a fully digitalized production and has completed the deployment of the 5G AI visual quality inspection system, which can achieve a defect rate control of power fittings below 0.02%.

In the future, the industry will focus on lightweight design and full life cycle carbon footprint management, to help the new power system transform to low carbon.
