The STL Testing For Suspension Insulator

What is the Tension Load?
 

Composite insulators primarily utilize unidirectional glass fiber reinforced resin core rods to support mechanical loads. The most prominent performance characteristics of these core rods are their high tensile strength and specific strength. The glass fibers within the core rod are oriented in a forward direction along the axial load-bearing axis, which imparts exceptional axial tensile strength to the product.

The relationship between mechanical load and the lifespan of composite insulators is significant. As the mechanical load increases, the duration for which a composite insulator can withstand stress decreases. Conversely, when a lower mechanical load is applied, the composite insulator tends to have an extended operational life. For instance, under a 100% failure load, composite insulators may sustain damage within approximately one minute. In contrast, when subjected to a 60% failure load, these insulators can endure for at least 96 hours before experiencing failure. At a 40% failure load,
