Fretting Wear Characteristics Of Overhead Wires With Protective Wires On Suspension Wires

32. Some tiny protrusions will appear in the micro-motion wear area of ​​the ab cable suspension clamp conductor. These protrusions may be caused by the accumulation of metal materials or local plastic deformation during the wear process.
Feature explanation: Describes the characteristics and causes of the protrusions. Metal accumulation or local plastic deformation forms protrusions.
33. During the micro-motion wear process of the overhead conductor with wire guard, the electromagnetic characteristics between the wire guard and the conductor will change. This is because the conductivity and magnetic permeability of the contact area have changed due to wear.
Feature explanation: Explains the changes in electromagnetic characteristics and causes. Wear changes the conductivity and magnetic permeability of the contact area.
34. The micro-motion abc suspension clamp wear characteristics are manifested as j hook suspension clamp The friction coefficient on the surface of the conductor will fluctuate at different wear stages. The initial suspension clamp for ab cable friction coefficient may be high. As the lubricating substances produced by suspension clamp for abc cable wear increase, the friction coefficient will decrease.
Feature explanation: Describes the characteristics of the change of suspension clamp for lt ab cable friction coefficient with the wear stage. The initial surface is rough and the friction coefficient is high. The increase of lubricating substances reduces the friction coefficient.
35. The micro-motion wear of the overhead wire with protective wire at suspension clamp will change the wind-induced response characteristics of the wire. This is because the wear changes the shape and surface roughness of the wire, affecting the interaction between the airflow and the wire.
Feature explanation: Point out the changes in the wind-induced response characteristics of the wire and the reasons. Wear changes the shape and roughness of the wire and affects the interaction between the airflow and the wire.
