Failures And Protective Measures Of Power Line Hardware

Cable Lugs Pay special attention to safety when using it. Today, the editor will explain to you how to pay attention to safety when using power line hardware.
1. The porcelain insulators on the power line hardware are affected by harmful components in the air, making the porcelain part dirty. In humid weather, the dirty layer absorbs moisture, which enhances the conductivity, increasing the power loss and easily causing flashover accidents.
2. The power line hardware line is mistakenly installed with unqualified porcelain insulators or due to the aging of the insulators, flashover breakdown occurs under the action of power frequency voltage. In this regard, porcelain insulators with flashover traces found during inspections should be replaced in time, and the replaced new porcelain insulators must undergo a withstand voltage test.
3. When the porcelain insulation part of the power line hardware is damaged by external forces, cracks or damage occurs, a large piece of porcelain skirt is knocked off, or there are cracks from the edge to the top, it should be replaced, otherwise it will cause insulation reduction and flashover accidents.
4. The cement pole is hit by external forces and the pole falls, such as car or tractor collision.
5. Strong winds break branches and drop them on the lines, or throw metal objects on the conductors, which can also cause short circuits between phases of the conductors or even breakage. In addition, when super-high cars pass under the lines or cranes operate under the lines, short circuits or breakages may also occur. Therefore, a certain spacing distance should be left when installing power line fittings on crossing and crossing lines.
6. The wires are damaged by long-term erosion and oxidation by moisture, atmosphere and harmful gases. Steel wires and lightning conductors are most likely to rust. When serious corrosion of the wires is found during inspections, they should be replaced in time.
7. The wires of the power line fittings are unevenly stressed, causing the pole tower to tilt. At this time, the pole's pull wire should be tightened or the line should be adjusted.
In places where the wires vibrate, the screws of the fittings are prone to fall off due to vibration and accidents occur. Therefore, during inspections and cleaning, the contact of the various parts of the fittings should be carefully checked to see if they are in good condition.
When using power line fittings, you must pay more attention to the above-mentioned aspects to avoid unnecessary troubles and safety incidents.
