Grounding wire in power system: it is an important thing to protect operators when voltage is unexpectedly displayed on equipment and lines that have been cut off.
It is generally used for outdoor line and substation construction. Possible situations during maintenance:
1. Return current in the line
2. Electrostatic induction generated by nearby electrified bodies
3. Line electrification caused by incorrect switching on of the staff. At this time, the grounding wire connects the live line with the earth, and the travel is a closed loop to ensure the personal safety of the operator. Therefore, the grounding wire is also a safe return line.
Duck billed (crocodile billed) impact grounding wire (throwing type for iron towers)：
As the name suggests, the drop type grounding wire is different from the rod type grounding wire we usually use. The drop type grounding wire does not have a grounding operating rod and is composed of a drop type grounding clamp, grounding soft copper wire, insulation rope, and grounding clamp. When in use, throw the electrical clamp from a high place and hang it on the conductive body.

The high-voltage switchgear shall break the fault current in case of grid fault; During normal operation, load current shall also be switched on and off, and there must be obvious breaking points, and separable contacts shall be equipped. In addition, in order to facilitate assembly and docking. The high-voltage switchgear will also be provided with butt contacts at appropriate positions; A sliding contact is also arranged between the moving part and the stationary part of the conductive body. There is contact surface resistance for both separable contact, butt contact and sliding contact. The size and stability of the contact resistance have a significant impact on the temperature rise of the switchgear during long-term operation and the dynamic thermal stability under the impact of fault current. There are many factors that determine the contact resistance, such as contact surface condition, contact pressure, material hardness and material resistivity. Throughout many factors, contact pressure is an important factor that has a wide range of changes and can be predicted by designers.
