#The production of composite insulators is like a precise art, divided into three parts: the production of epoxy glass pulling rods, the synthesis of adhesive materials, and the assembly.

Epoxy glass pulling rod: from glass fiber impregnation with epoxy resin, vacuum injection infiltration, continuous extrusion molding, to high-temperature curing, each step requires precise control to ensure perfect fusion of fibers and resin.

Rubber production: The precise ratio of silicone rubber raw rubber with various additives such as white carbon black and aluminum hydroxide is mixed and sulfurized to form a uniform synthetic rubber, ensuring stable material properties.

Assembly process: Metal fittings are polished and sandblasted to ensure clean contact surfaces and increase friction; Core rod polishing, cleaning, and drying to remove impurities and ensure bonding quality; Coating coupling agent to strengthen the chemical connection between silicone rubber and core rod; Finally, injection vulcanization solidifies the silicone rubber to form a sealed and durable umbrella skirt.

Rigorous factory inspection: After completing all steps, insulators will undergo factory tests in accordance with GB 19519-2014 standards, including mechanical failure loads and steep wave impacts, to ensure that each product meets the industry's highest quality standards.

Every process and every detail is aimed at ensuring the excellent performance of the rod-shaped suspension composite insulator and providing a solid guarantee for the safe operation of the power system. This is the technological story behind them, a precise journey from raw materials to finished products.
