Composite long-rod insulators are often used as suspension insulators or tension insulators, so the tensile resistance performance is of particular concern. The mechanical properties of composite insulators are mainly related to the core rod, fittings, and their assembly methods.
The tensile load of FRP rods is mainly borne by nearly one million glass fibers (for example, a core rod with a diameter of 16mm has approximately 80,000 single glass fibers in its cross-section). Therefore, the selection of core rod raw materials and the extrusion molding process play a decisive role in quality.
According to the experimental results of Claude de Tourreil's team at the Hydro-Québec Research Institute, forged fittings perform better than cast fittings, and crimped fittings exhibit more excellent tensile properties than wedge-shaped and tapered fittings.
JD Electric purchases high-quality glass fibers from the world's leading glass fiber manufacturers and manufactures high-tensile-strength core rods independently by relying on its own mature core rod manufacturing process. At the same time, JD Electric independently conducts forging and machining of fittings to produce high-strength and low-tolerance fittings. For high-load products, experienced workers with more than 5 years of crimping experience strictly execute the secondary crimping process in accordance with the standard operating procedures to ensure the reliable connection between the core rod and the fittings. The finished products will be subjected to tensile tests one by one to ensure that each product can operate safely in the global power system.
