Wire and cable pay attention to these points, can extend the service life

As an important component of the power system, wires and cables must be inspected and maintained regularly during use. This can ensure our daily electricity safety and prolong the service life of the wires and cables. The following editor will share the details of the wires and cables. Matters needing attention in daily use.

1. Violation by external forces

If wires and cables are laid in areas with strong acid and alkali properties, they will usually be corroded. The thickness of the protective layer will be eroded by organic chemical or electrolytic methods for a long time, resulting in ineffective protective layer thickness and reduced insulation layer. It can also cause cable failure. Therefore, it is necessary to analyze the local soil quality before laying wires and cables.

2. Natural weather

When installing wires and cables, try to avoid being exposed to the sun or being damaged by strong winds and heavy rains, because the accumulation of wires and cables over time 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 cable to have too high temperature and thermal breakdown of the insulation, which may cause an explosion and fire.

4. Overload operation

Wires and cables should not be overloaded. This is because of the thermal effect of the current. The load current will inevitably cause the electric 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 damage. Heat, which in turn causes the temperature of the cable to rise. During long-term overload operation, excessively high temperature will accelerate the embrittlement of the insulating layer, resulting in thermal breakdown of the insulating layer.

Wire and cable is one of the core and most important elements of the current cable system. In our daily application, we need to check and repair at any time, and take some defensive measures in advance, so as to extend the service life of the wire and cable.
