Share The Technical Measures To Prevent Fire Accidents on Photovoltaic Cables

Nowadays, the use of photovoltaic cables is becoming more and more widespread, but with its popularity in the country's power supply lines, some of its safety issues have gradually attracted attention, especially the cable fire accidents that have occurred in recent years, is the most direct reminder of the use of cables to pay extra attention to one of the ways, then, what are the measures to prevent cable fire accidents of note? The following XSD cable will be explained to you.

Firstly, when laying the cable, shall not damage the cable sheath or let the cable by mechanical damage, so as not to cause the cable due to poor insulation and be penetrated and thus generate an electric arc, indirectly leading to cable insulation materials and external linen on fire, when laying the cable through the wall, floor and all the alignment holes, should be tightly blocked. In this way, once the cable fire, you can effectively isolate or limit the scope of combustion to prevent the spread of fire, but when the cable trench and cable temperature is too high, attention should be paid to ventilation.

Secondly, to prevent the cable in long-term overload operation, regular measurement and monitoring of the cable load and take appropriate measures to prevent small animals such as rats from biting the cable insulation, regular inspection of the cable head and intermediate joints, such as heavy rain, floods and other special circumstances need to check the following three points in a timely manner:

1, Check the terminal head insulation sleeve for damage and discharge phenomenon, the terminal head filled with cable glue, more should be timely check whether there is no oil leakage, overflow glue phenomenon;

2, Check whether the cable connection between the lead and the terminal is intact and there is no heat phenomenon.

3, Check whether the cable intermediate joint is deformed and whether the temperature is normal.

Third, the cable laying position difference should not exceed the specified requirements, so as to avoid the phenomenon of oil leakage phenomenon, which in turn causes the upper part of the cable oil dry moisture absorption, the lower cable head due to increased oil pressure and oil leakage, these phenomena are likely to lead to cable fire, cable head, cable intermediate box production must ensure quality, to avoid poor sealing, welding is not strong, improper selection of materials, manufacturing process is incorrect, etc. caused by moisture intrusion, resulting in insulation breakdown and fire. Cause insulation breakdown and fire.

Finally, the line should be regularly inspected for safety. For wires, electrical equipment, etc., at least one professional needs to conduct a thorough inspection once a year, especially the long life of the circuit at the joints. If the wire is found to be aging, damaged, poor insulation and other unsafe conditions, it must be repaired and replaced in a timely manner to ensure the use of electricity. Security, and finally remind everyone that when buying wire and cable, be sure to look for regular manufacturers and check the quality.
