A cable is a wire made of one or more insulated conductors and an outer insulating protective layer that transfers power or information from one location to another. Cables include power cables , control cables , compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire resistant cables, marine cables, mining cables, aluminum alloy cables, and the like. They are composed of single or multi-strand wires and insulating layers for connecting circuits, electrical appliances, and the like. Cables have so many uses, what should I do if the cable bursts? How to prevent it? Electric Tiger Xiaobian introduced for everyone.
The trick to prevent cable fire and explosion:
1. Ensure the construction quality, especially the production quality of the cable head must strictly meet the requirements.
2. Conduct cable testing regularly and deal with it immediately if there is a problem.
3. Install the fire alarm device to immediately find the fire and avoid 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 causing a short circuit.
5. Enhance cable operation monitoring to avoid overloading the cable.
6. Accidentally clean the dust accumulated on the cable to prevent the cable from igniting due to spontaneous combustion of the accumulated dust.
7. Enhance the periodic calibration maintenance of the cable circuit switch and protection to ensure its reliable operation.
8. When laying the cable, keep a sufficient distance from the heat pipe, control cable ≥ 0.5 m; power cable ≥ 1 m; control cable and power cable should be slotted, layered and separated, it is impossible to overlap between layers; In accordance with the demarcated parts, the cable should be fire-retardant and heat-insulated.
9. Equipped with the necessary fire fighting equipment and facilities. Overhead cables can be fired with common fire-fighting equipment, but automatic or remote-controlled fire-extinguishing devices such as 1301 fire-fighting devices and water-spray fire-fighting devices should be installed in cable sandwiches, shafts, trenches and tunnels.
10. Take fire retardant measures.
