How to put out a Power cable fire

Once the cable catches fire, it should be extinguished by the following methods:

(1) Cut off the power supply of the fire cable. If the cable catches fire, no matter what the cause is, the power supply should be cut off immediately. Then, according to the path and characteristics of the cable, carefully check to find out the fault point of the cable, and at the same time, personnel should be quickly organized to put it out.

(2) Cut off the power supply of the non-faulty cable in case of fire in the cable trench. When the cables in the cable trench catch fire, if the cables laid side by side in the same trench have obvious possibility of fire, the power supply of these cables should be cut off. If the cables are arranged in layers, first cut off the power supply of the heated cable above the fire cable, then cut off the power supply of the cable side by side with the fire cable, and finally cut off the power supply of the cable below the fire cable.

(3) Close the fire door of the cable trench or block both ends of the cable trench. When the cable in the cable trench catches fire, in order to avoid air circulation and to quickly extinguish the fire, the fire door of the cable trench should be closed or both ends should be blocked, and the fire should be extinguished by suffocation.

(4) Do a good job of personal protection when putting out cable fires. Since the fire of the cable will produce a lot of smoke and poisonous gas, the rescue personnel should wear a gas mask when putting out the fire of the cable. In order to prevent personal electric shock during the rescue process, the rescuers should also wear rubber gloves and insulating boots. If one phase of the high-voltage cable is found to be grounded, the rescuers should observe: Do not enter indoors within 4m from the fault point, and do not enter outdoors from the fault. Points within 8m, so as not to step voltage and contact voltage hurt people. Rescue of injured personnel is not limited to this limit, but protective measures should be taken.

(5) Fire extinguishing equipment used to extinguish cable fires. Fire extinguishers should be used to extinguish cable fires, such as dry powder fire extinguishers, "1211" fire extinguishers, carbon dioxide fire extinguishers, etc.; dry sand or loess can also be used to cover; if water is used to extinguish fire, it is best to use water spray; Other methods may be used to put out the fire. After the power supply is cut off, water can be poured into the cable trench, and the fault can be sealed and extinguished with water.

(6) When fighting a cable fire, it is forbidden to directly touch the steel armor of the cable and the moving cable with your hands.

Be sure to master the method of cable fire extinguishing in order to protect yourself and your family in the event of a fire.
