Wear Characteristics Of Wire Guard Wire Frame Suspended By Suspension Wire Clamp

15. Some tiny rust spots will appear in the micro-motion wear area of ​​the conductor. This is because the moisture and oxygen in the air react chemically with the fresh metal surface produced by wear.
Feature explanation: Describes the characteristics and causes of rust spots. Moisture and oxygen react with the fresh metal surface to form rust spots.
16. After micro-motion wear of the fiber suspension clamp overhead conductor with protective wire, the surface hardness of the cable suspension clamp protective wire will increase in the contact area. This is due to the work hardening phenomenon during the micro-motion process, which changes the metal crystal structure.
Feature explanation: Point out the changes in the surface hardness of the aerial cable suspension clamps protective wire and the reasons. Work hardening changes the metal crystal structure and increases the hardness.
17. The wear of the contact area between the conductor and the angle suspension clamp protective wire will cause the temperature of the area to rise during the micro-motion process. This is because friction generates heat, and the heat accumulates in the contact area and is not easy to dissipate.
Feature explanation: Explains the temperature changes and reasons. Friction generates heat and heat dissipation is difficult to increase the temperature of the harga suspension clamp contact area.
18. The characteristic of fretting wear is that the wear degree of the outer aluminum strands of the conductor gradually decreases from the outside to the inside. This is because the outer aluminum strands are in direct contact with the protective wire and are subjected to greater friction and pressure.
Feature explanation: Describes the distribution characteristics and reasons for the wear degree of the outer aluminum strands of the conductor. The outer layer is subjected to greater force, resulting in more severe wear.
19. The fretting wear of the overhead conductor with protective wire at messenger suspension clamp will cause the shape of the protective wire to be slightly deformed suspension clamp with i hook under long-term action. This is because repeated fretting and stress have caused irreversible deformation of the protective wire material.
Feature explanation: Point out the changes in the shape of the protective wire and the reasons. Repeated fretting and stress cause irreversible deformation of the protective wire.
20. During the fretting wear process, the microstructure of the surface of the conductor will change, such as the orientation and size of the grains will change. This is due to plastic deformation and stress during the fretting process.
Detailed explanation of features: It explains the changes in the microstructure of the conductor surface and the reasons for it. Plastic deformation and stress change the grain orientation and size.
21. When the overhead conductor with protective wire is worn, the contact area between the conductor and the protective wire will gradually increase. This is because the wear makes the contact surface smoother, and the plastic deformation of the conductor also plays a certain role.
Detailed explanation of features: It describes the changes in the contact area and the reasons for it. Wear makes the surface smoother and the plastic deformation of the conductor increases the contact area.
