1. Apply fire-resistant paint on the surface of the cable.
2. Wrap the parts of the cable that need to be flameproof with fireproof tape.
3. Use refractory materials to seal the holes where the cables pass through the walls, bottoms, and shafts tightly to avoid the spread and spread of high-temperature smoke when the wires are on fire caused the fire to expand.
4. Set up heat-resistant and fireproof panels between the cable-layers, segmented partition walls, and fire doors to prevent the cables from flaring between the layers and expand the fire.
5. Wrap the cable with a heat-insulating and flame-resistant material. When there is a fire around the cable, the wrapped line is isolated from the fire by the heat-resistant and flame-resistant material to avoid burning. If the cable itself catches fire, the lack of oxygen in the bandage can cause the fire to extinguish itself, preventing the fire from spreading to the outside of the application.
In addition to the above, we also have to choose the material of the cable. Zhujiang Cable uses an oxygen-free copper core to make the cable, which has the characteristics of high mechanical strength, good environmental stress resistance, excellent electrical performance, and chemical corrosion resistance, and is light in weight. The structure is simple and easy to use.
Ten tricks to prevent cables from catching fire and exploding
1. Ensure the construction quality, especially the cable head's production quality, must strictly comply with the specified requirements.
2. Carry out the cable test regularly, and deal with it immediately if any problems are found.
3. Install a fire alarm device to detect the fire immediately to prevent the cable from catching fire.
4. The cable trench should be kept dry to prevent the cable from being damp, causing the insulation to drop and cause short circuits.
5. Enhance cable operation monitoring to avoid cable overload operation.
6. Occasionally clean the dust accumulated on the cable to prevent spontaneous combustion of the accumulated dust and cause the thread to catch fire.
7. Enhance the regular verification and maintenance of the cable loop switch and protection to ensure its reliable action.
8. When laying the cable, keep a sufficient distance from the heat pipe, control cable ≥ 0, 5 meters; power cable ≥ 1 meter; control cables and power cables should be slotted, layered, and arranged separately. It is impossible to overlap between layers; For the parts that do not meet the delimitation, the cable shall be flame-retardant and heat-insulated.
9. Equipped with necessary fire fighting equipment and facilities. Standard fire extinguishing equipment can be used to extinguish the fire of overhead cables, but automatic or remote control fire extinguishing devices, such as 1301 fire extinguishing devices, water spray fire extinguishing devices, etc., should be installed in cable interlayers, shafts, trenches, and tunnels.
10. Take fire and flame retardant measures.
Fire-retardant measures for cables include:
(a) Apply fire-resistant paint on the surface of the cable.
(b) Wrap the parts of the cable that need to be flameproof with fireproof tape.
(c) The holes where the cable passes through the wall, the bottom of the plate, and the shaft are tightly sealed with refractory materials to avoid the spread and spread of high-temperature smoke when the cable is on fire, which will cause the fire area to expand.
(d) Set up heat-resistant and fireproof panels between the cable-layers, segmented partition walls, and fire doors to prevent the cable-layers from combusting and expand the fire.
(e) Wrap the cable with a heat-insulating and flame-resistant material. When the line is on fire, the wrapped cord is isolated from the fire by the heat-insulating and flame-resistant material to avoid burning. If the cable itself catches fire, the lack of oxygen in the bandage can cause the fire to extinguish itself, preventing the fire from spreading to the outside of the application.
