Wire and cable as an important part of the power system, quality is particularly important, in addition to the selection of large-scale cable manufacturers in the procurement of quality assurance, the use of the process also to carry out regular inspection and maintenance, after all, operation safety is related to everyone's life and property safety. At present, the service life of wire and cable products produced by regular manufacturers is not less than 20 years, or even up to 30 years, and the service life of some special cables is longer, but the specific time can be used, external factors often affect the length of its life, such as insulation layer damage, aging, corrosion and so on. Today I tell you what aspects should be paid attention to in the process of use and how to maintain to extend the service life of the cable.

Reasonable laying environment and route

If the wire and cable are laid in areas with particularly strong acid and alkali properties, it will lead to the insulation layer of the wire and cable, that is, the outer layer of the cable is eroded, and the long-term organic chemical etching or electrolysis etching will lead to the ineffective thickness of the protective layer and the reduction of the insulation layer, which will also cause cable failure. The insulation layer of the exterior of the household wire is made of plastic and rubber, if the use of a long time or not properly laid, the insulation performance gradually decreases, slowly aging and hardening, brittle or falling off, then the insulation effect is not available.

If two wires touch together or the fire line touches something connected to the earth, there will be a phenomenon of electricity running, so that the temperature of the local wire will rise, produce sparks, and produce accidents. Therefore, when laying, we should choose the right environment and find the relevant personnel to design the line.



Cable)

Select a matching model

If the wire and cable are installed in the hot sun or subjected to heavy wind and rain, because the cumulative wire and cable will cause the embrittlement of the sheath to accelerate, reduce the service life of the wire and cable.

The external natural environment and pyrogen can also cause the cable temperature to be too high, the thermal breakdown of the insulation layer, and the explosion and fire. Therefore, it can not be installed in the sun, the temperature is too high environment, if you need to operate at high temperature, must choose special high temperature cable.

In wet conditions, when the water is immersed into the metal conductor, it is more likely to short-circuit leakage, in addition to affecting the service life of the wire, but also easy to cause accidents, to choose waterproof cables.

Armored or special cables are needed in the environment where there are more insects or mice, and the requirements for cable fire rating are different in important places. Therefore, it is recommended that you choose the appropriate wire and cable model according to the scenario of wire and cable use.

Pay attention to the cable storage environment

When the wire is stored, it is strictly prohibited to contact with acid, alkali and mineral oil, and it should be isolated from these corrosive substances. Avoid storing cables exposed in the open air if possible. Correct storage and transportation of wire and cable products

Avoid overload of wires and cables

The load current will inevitably cause the electric conductor to burn, in addition, the skin effect of charge, the eddy current loss of steel armor, and the dielectric loss of the insulation layer will also generate additional heat, which will increase the temperature of the cable. During long-term overload operation, excessive temperature will accelerate the embrittlement of the insulation layer, resulting in thermal breakdown of the insulation layer.

Perform regular line maintenance

The demand for electricity in modern life is getting higher and higher, it can even be said that all the time can not be separated from electricity, in order to prevent overload operation, it is necessary to regularly check the use of electricity and lines, timely maintenance, overhaul and replacement.

Power can bring convenience to everyone, but improper use will also bring harm, Qingdao cable remind you must purchase national standard wire and cable, and installation process in accordance with the guidance of technical personnel, regular maintenance and inspection.
