Judgment Standards for the Quality and Reliability of Insulators

Historically, insulators were primarily used on utility poles. With the advancement of technology, they evolved into strings of disc-shaped units suspended from high-voltage transmission towers. These units, typically made of glass or ceramics, are designed to increase creepage distance. Insulators play two fundamental roles in overhead transmission lines: supporting the conductors and preventing current from returning to the ground. These functions must be guaranteed under all environmental and electrical load conditions. An insulator must not fail due to mechanical or electrical stresses; otherwise, the operational life and safety of the entire transmission line will be compromised. 1. Standards for Insulation Resistance The quality...

Root Cause Analysis of Core Rod Fracture During Crimping or Tensile Testing

I. Failure Characteristics The fracture typically occurs inside the ball-end or socket-end metal fitting. The primary symptom is a tensile failure load that is significantly lower than the rated design value. II. Root Cause Analysis Excessive Crimping Force: The pressure applied during the crimping process exceeds the radial compressive strength of the core rod, leading to internal structural damage. Improper Crimping Position: The crimping dies are not centered; the compression zone should ideally be located in the middle of the fitting's connection area. Poor Machining Precision of Fittings: Issues such as eccentricity of the inner hole, insufficient cylindricity, or internal tapers can...
