Long-term Performance Of Bolt-type Tension Clamps Under Ice Load Conditions

Overhead lines in high-latitude and cold and humid regions often face icing conditions. Ice layers adhering to line components can cause load changes and dynamic stress changes. In such environments, bolted type strain clamp serves as a mechanical connection and wire fixation component, forming a fundamental part of operational reliability.

Under long-term icing load scenarios, the entire line system is subjected to the combined effects of static ice weight and dynamic loads that change over time. Icing increases conductor weight, requiring conductors dead end strain clamp to withstand higher tensile levels than under normal conditions, while simultaneously resisting the effects of temperature and humidity changes on fastener performance. High-strength materials and a rational structural design can improve conductors bolted dead end clamp's resistance to sustained loads, thereby extending their service life.
