Why maintain cables? This is because unmaintained cables may lead to some unknown hazards. And what are the benefits of properly maintaining PV cables?
If the photovoltaic cable is not maintained, the risks will be as follows::
The cable is mainly insulated by the outer layer of the sheath. After a long time, it will be corroded by corrosive gas, and the insulation performance will gradually decrease, it will gradually age and harden, and the texture will become fragile or fall off. If the two wires and cables are in contact with each other or the charged end is in contact with a certain item on the earth, the thing connected to the ground will leak electricity and run electricity. This will increase the temperature of local wires, creating sparks and causing a fire.
Regular maintenance of the cable can make the cable work normally, use more smooth, not easy to leakage, tripping and other faults, this maintenance work will provide an effective guarantee for the safety performance of the use of photovoltaic cable process: in the long run, it can also reduce the waste of power resources, save resources, so as to effectively reduce a large number of unnecessary expenses.
The maintenance of photovoltaic cable includes:
During transportation, especially at low temperatures (usually below 5°C), so do not drop household wires or cable trays with cables from heights, the throwing or dropping of cables may cause the insulation sheath to break；
Avoid wire damp, heat, corrosion or abrasion, when using the wire please try to keep it away from these unhealthy environment, at the same time do not let the cable excessive use, in order to avoid accidents；
Pay special attention to the lines that are prone to flooding. If necessary, you can ask an electrician to rearrange the lines and take measures such as overhead and moisture-proof protection. After using for a period of time, the wires should be checked regularly, especially those installed in old buildings or not repaired for a long time.
Suggestions: We should focus on cable load monitoring, because overload is very harmful to the cable, so should often measure and monitor the cable load, and can measure the cable load through the clamp ammeter, control cable in principle will not overload, and the cable should be kept within the specified allowable continuous current carrying range, in order to prevent premature aging of the cable insulation layer, line voltage should not be too high, Generally it should not exceed 15% of the rated voltage of the cable.
