How to prevent wires and cables from catching fire


The main causes of electrical line fires are: short circuits, poor contact, overloaded lines, line leakage, sparks and arcs, and cable fires.

1. Ensure the construction quality, especially the quality of the cable head must strictly comply with the requirements.

2. Strengthen cable operation monitoring to avoid cable overload operation.

3. Carry out the cable test on schedule and deal with it when it is found abnormal.

4. The cable trench should be kept dry to prevent the cable from getting wet, causing the insulation to fall and causing a short circuit.

5. Regularly clean the accumulated dust on the cable to prevent the accumulated dust from spontaneously igniting and causing the cable to catch fire.

6. Strengthen the regular check and maintenance of the cable loop switch and protection to ensure its reliable operation.

7. When laying the cable, keep a sufficient distance from the heat pipe, the control cable is not less than 0.5 meters, and the power cable is not less than 1 meter. Control cables and power cables should be divided into slots, layered and arranged separately. Do not overlap between layers. For the parts that do not meet the requirements, the cable shall be fire-retardant and heat-insulated.

8. Install a fire alarm device to detect the fire in time to prevent the cable from catching fire.

9. Take fire and flame retardant measures.

Xiaobian explain the fire and flame retardant measures of the cable:

1. The cable is wrapped with heat-resistant and flame-resistant material. When the cable is on fire, the cable wrapped by Zhengzhou wire and cable 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 self-extinguish, preventing the fire from spreading outside the bandage.

2. Pass the cable through the wall, the bottom of the plate, and the hole of the shaft with a refractory material tightly to prevent the expansion of the fire surface caused by the diffusion and spread of high-temperature smoke when the cable catches fire.

3. Brush fire-resistant paint on the cable surface.

4. Wrap the fire-proof parts of the cable with fireproof tape.

5. Install heat-resistant fire barriers between the cable layers to prevent flammability between the cable layers and expand the fire.

6. Set up partition walls and fire doors in the cable channel to prevent the cable from burning and expand the fire.

7. Equip necessary fire extinguishing equipment and facilities. Overhead cables can be extinguished with commonly used fire extinguishing equipment, but automatic or remote control fire extinguishing devices, such as 1301 fire extinguishing devices and water spray fire extinguishing devices, should be installed in cable mezzanines, shafts, trenches and tunnels.
