摘要

As commonly known, the endurance of overhead conductors is limited by fretting fatigue. The most severe fretting fatigue damage occurrence is the suspension clamp, as a superposition of many different loads occurs in the conductor/clamp assembly. Therefore, this paper focuses on two modification methods, which aim to reduce the fretting fatigue loading in such assemblies. The investigated modification methods are a deep cryogenic treatment and a surface coating. To study the effect of both methods on the duration of overhead conductors, comparative fretting fatigue tests with real conductor/clamp contacts were carried out. A reduced amount of wire breaks was found for both modification methods. Especially the first wire break occurred significantly delayed using deep cryogenic treated and coated suspension clamps (20% for the deep cryogenic treated and 60% for the tests with coated clamps). The post mortem analysis showed severe damage marks in the suspension clamps. The use of the surface coating led to a reduced amount of damage in the suspension clamps.
