As an important component 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 prolong the service life of wires and cables. Wires and cables need to be paid attention to in daily use. matter.

1. External force infringement

If the wire and cable are laid in areas with strong acid and alkali properties, it will usually cause the wire and cable to be corroded, and the thickness of the protective layer will be corroded by organic chemical or electrolytic methods for a long time, resulting in invalid protective layer thickness and reduced 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 sun or heavy wind and rain, because the accumulation of wires and cables will 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 will also cause the temperature of the cable to be too high, the thermal breakdown of the insulation layer, and even an explosion and fire.

4. Overload operation

Do not overload the wire and cable, this is because of the heating effect of the current, the load current will definitely cause the electrical conductor to heat up, and the skin effect of the charge, the eddy current loss of the steel armor, and the dielectric loss of the insulating layer will also produce extra heat. Heat, which in turn increases the temperature of the cable. During long-term overload operation, too high temperature will accelerate the embrittlement of the insulating layer, resulting in thermal breakdown of the insulating layer.

Wire and cable are one of the core and most important elements of the current cable system. In our daily applications, we need to check and maintain at any time, and take some defensive measures in advance, which can prolong the service life of the wire and cable.
