As important components of the power system, wires and cables must be inspected and maintained regularly during use. This can ensure the safety of our daily electricity use and extend the service life of wires and cables. Let's share the daily use of wires and cables. Things to note.
1. External invasion
If wires and cables are laid in areas with particularly strong acid and alkali properties, the wires and cables will often be corroded. The protective layer will be corroded by organic chemicals or electrolytes for a long time, resulting in the loss of protective layer thickness and reduction of the insulation layer. It can also cause cable failure. Therefore, before laying wires and cables, it is necessary to analyze the local soil quality.
2. Natural weather
When installing wires and cables, try to avoid exposure to the scorching sun or strong winds and heavy rains, because the accumulation of wires and cables over time will accelerate the embrittlement of the sheaths and reduce the service life of the wires and cables.
3. Suitable temperature
The external environment and heat sources where the cables are located can also cause the cable temperature to be too high and the insulation layer to thermally breakdown, leading to an explosion and fire.
4. Overload operation
Do not overload the wires and cables. This is because of the thermal effect of the current. The load current will inevitably cause the conductor to become hot. In addition, the skin effect of the charge, the eddy current loss of the steel armor, and the dielectric loss of the insulation layer will also cause additional heat. heat, thereby causing the temperature of the cable to rise. During long-term overload operation, excessive temperature will accelerate the embrittlement of the insulation layer, causing the insulation layer to be thermally broken down.
Wires and cables are one of the core and most important elements of the current cable system. In daily applications, we need to check and repair at any time and take some defensive measures in advance, which can extend the service life of wires and cables.
