1, to ensure the quality of construction, in particular, the production of cable head must strictly meet the requirements.
2. Strengthen cable operation monitoring to avoid overloaded cable operation.
3. Conduct the cable test as scheduled, and deal with it in a timely manner if it is found to be abnormal.
4. The cable trench should be kept dry to prevent the cable from getting wet and causing the insulation to drop, causing a short circuit.
5. Clean up the accumulated dust on the cable regularly to prevent the cable from catching fire when the accumulated dust is self-ignited.
6, to strengthen the regular inspection and maintenance of the cable loop switch and protection to ensure its reliable operation.
7. When the cable is laid, it must be kept at a sufficient distance from the heat pipe. The control cable should be no less than 0.5 meters. The power cable should not be less than 1 meter. Control cables and power cables should be divided into slots, layers and separate layouts. They cannot be placed in layers. For parts that do not meet the regulations, the cables shall be fire-retardant and heat-insulated.
8, install a fire alarm device to discover the fire in time to prevent the cable from catching fire.
9, take fire retardant measures. Fire-retardant measures for cables include:
(1) Wrap the cable with heat-insulated and flame-retardant materials. When the surrounding of the cable is ignited, the wrapped cable can be insulated from fire by insulation and flame-proof materials. If the cable itself catches fire, the lack of oxygen in the body of the dressing allows the fire to self-extinguish, preventing the fire from spreading to the outside of the dressing.
(2) The cables shall be sealed tightly through the holes of the wall, the bottom of the plate, and the shaft with refractory material to prevent the high temperature smoke from spreading and spreading and causing the fire surface to expand when the cable catches fire.
(3) Brush fireproof coating on the surface of the cable.
(4) Wrap the area where the cable needs to be flameproof with a fireproof tape.
(5) Heat-resisting fire-retardant panels are installed between the cable layers to prevent flammability between the cable layers and expand the fire.
(6) Set partition walls and fire doors in the cable channel to prevent the cable from igniting and expand the fire.
10. Equipped with necessary fire-fighting equipment and facilities. Overhead cable fires can be saved by commonly used fire extinguishing equipment, but automatic or remotely controlled fire extinguishing devices such as 1301 fire extinguishing devices and water spray fire extinguishing devices should be installed at cable mezzanines, shafts, trenches and tunnels.
Fire suppression of cable fires Fire suppression fires of cables When a cable fire occurs, it is necessary to promptly report an alarm, immediately identify the system and direction of the fired cable, adjust the operating mode of the fired cable as soon as possible, and cut off the power supply of the fired cable. When the cable is burned, toxic gas will be generated, so special attention must be paid to the protection against fire of the cable.
