Product Details

Our company produces and sells FZSW type composite pillar insulators, which have high bending strength, impact resistance, shockproof and anti-brittle fracture performance. At the same time, they have good hydrophobicity, aging resistance, resistance to leakage current tracking, and resistance to electrical erosion, as well as being lightweight and easy to install, making them very effective in power station facilities. The installation dimensions at the top and bottom of the insulator correspond to the respective porcelain pillar sizes and can be used interchangeably. The core rod uses ERC high-temperature acid-resistant rods, and the interface between the core rod and silicone rubber is coated with a special coupling agent. The umbrella sleeve is made using a one-time overall molding process under high temperature and high pressure, combined with a computer-monitored two-stage vulcanization process, which extends the product's service life. Fore Electric's advanced production equipment and manufacturing processes, along with complete testing equipment and methods, ensure that all technical indicators of the insulator products meet relevant international standards, making it a new generation of high-performance insulators for high voltage transmission and transformation lines.
