A fire in a cable will of course lead to a power failure accident for a period of time, and disassembly and assembly of the cable is also very troublesome. At the same time, it will also cause other cables in the cable ditch to catch fire, resulting in significant and huge losses. For this reason, we must pay attention to it. The specific measures to prevent cable fire accidents are as follows:
When laying the cable, the outer skin of the cable should not be damaged, and the cable should not be mechanically damaged to prevent the cable from breaking through due to abnormal insulation and causing an arc, which will cause the cable insulation material and the outsourced hemp yarn to catch fire.
All cable holes such as walls and floor slabs through which the cable passes should be strictly sealed.In this way, if the cable catches fire, the burning area can be isolated or restricted to prevent the spread of the fire.If the cable ditch and cable temperature are too high, pay attention to ventilation.
Protect the cable.Prevent the cable from running under load for a long time, detect and monitor the load of the cable from time to time, improve measures to prevent small animals such as rats from biting the insulation of the cable, and routinely check the cable head and intermediate joints.
In case of abnormal conditions such as heavy rain, heavy water, etc., it should be detected immediately.:
①The insulating sleeve of the terminal head should be checked for damage and discharge problems. For the terminal head filled with cable glue, it should also be checked for oil spills and glue spills.;
②Check whether the wiring of the leads and terminal blocks is good, and whether there is abnormal heating.;
③Check whether the middle joint of the cable is bent and whether the temperature is normal.
