As an important component of the power system, wires and cables must be regularly inspected and maintained during use, which can ensure our daily electricity safety and prolong the service life of wires and cables. Below, the editor will share the precautions that wires and cables need to pay attention to in daily use.
As an important component of the power system, wires and cables must be regularly inspected and maintained during use, which can ensure our daily electricity safety and prolong the service life of wires and cables.

1. External force infringement
If wires and cables are laid in areas with strong acid and alkali properties, it usually leads to erosion of the wires and cables. The thickness of the protective layer is eroded by organic chemical or electrolytic methods for a long time, resulting in ineffective protective layer thickness and reduced insulation layer, which can also cause cable failures. Therefore, before laying wires and cables, it is necessary to analyze the local soil conditions.
2. Natural weather
When installing wires and cables, it is advisable to avoid exposure to direct sunlight or exposure to strong winds and heavy rain, as the accumulation of time can accelerate the embrittlement of the sheath and reduce the service life of the wires and cables.
3. Suitable temperature
The external natural environment and heat source where the cable is located can also cause the temperature of the cable to be too high, thermal breakdown of the insulation layer, and even explosion and fire.
4. Overload operation
Do not operate wires and cables under overload, as the thermal effect of current and the load flow rate will inevitably cause the conductor to overheat. In addition, the skin effect of charges and the eddy current loss of steel armor and insulation layer dielectric loss will also generate additional heat, which will cause the temperature of the cable to rise. During long-term overload operation, excessively high temperatures can accelerate the embrittlement of the insulation layer, leading to thermal breakdown of the insulation layer.
Wire and cable are currently one of the most core and important elements of cable systems. In daily applications, we need to inspect and repair them at any time, and take some defense measures in advance, which can extend the service life of wire and cable.
