Core Viewpoint - The application of a new high-performance nano insulation coating significantly enhances the protection of power cables in coastal areas, improving power supply safety and reliability, especially in preparation for the upcoming Spring Festival [1][3]. Group 1: Technology and Innovation - The new material used is a high-durability polysilazane nano insulation coating, which provides super hydrophobic, self-cleaning, and water-repellent migration properties, effectively blocking moisture, air, and pollutants [3][4]. - The innovative "live working + insulation spraying" approach allows for maintenance without interrupting power supply, minimizing impact on local businesses and residents [3][4]. Group 2: Operational Implementation - The spraying operation was conducted by the State Grid Putian Power Supply Company in collaboration with the Fujian Electric Power Research Institute and Zhongqi New Materials (Fujian) Co., Ltd., marking a pilot application in Putian [3][4]. - The operation involved a specialized insulated spray gun and compressed air to evenly apply the coating, ensuring a "zero perception" experience for users during the process [3]. Group 3: Future Plans - Following the pilot application, the company plans to integrate drone inspections to accurately identify insulation layer aging, cracking, and damage, prioritizing high-risk areas for the application of the new coating [4]. - The goal is to scale up the use of this technology to support the development of a safe, reliable, and green new distribution network [4].
