I. How to prevent wire and cable fires? Wire and cable are materials used for power, electrical and related transmission purposes. "Wire" and "cable" and there is no strict boundary. Usually the number of cores, the product diameter is small, simple structure of the product is called wire, there is no insulation is called bare wire, the other is called cable. Well, in this way, wire and cable is very easy to heat overload. Power cable manufacturers in the selection of wire and cable as much as possible when the cable, the wire and cable full performance is certainly stronger, but also can service life is also more long-lasting, then how to prevent wire and cable due to overloading and fire, and how we should select the wire and cable?1. Adopt fire-retardant measures.2. Enhance the monitoring of the cable operation, to avoid overloading of the cable.3. Regularly carry out the cable test, found that there is a problem should be handled immediately.4. Installation of fire alarm devices to immediately detect the fire, to avoid cable fire. 5. Occasionally sweep the dust accumulated on the cable, to prevent spontaneous combustion of the accumulated dust caused by the cable fire. 6. Cable trench should be kept dry, to prevent the cable from moisture, resulting in insulation degradation, resulting in a short circuit. 7. Ensure that the quality of the construction, in particular, the quality of the production of the cable head should be in strict conformity with the requirements of the regulations. 8. Enhance the regular calibration maintenance of the cable circuit switch and Enhance the cable circuit switch and protection of regular calibration and maintenance, to ensure that its action is reliable. 9. cable laying should be kept at a sufficient distance from the heat pipe, control cable ≥ 0.5 meters; power cable ≥ l meters. Control cables and power cables should be divided into grooves, layers and separate arrangements, it is not possible to overlap between layers placed. Not in line with the delineation of the parts of the cable should take flame retardant, heat insulation measures. 10. equipped with fire-fighting equipment and facilities. Overhead cable fire can be commonly used fire extinguishing equipment to fight, but in the cable mezzanine, shafts, trenches and tunnels, etc. It is appropriate to install automatic or remote-controlled fire extinguishing devices, such as 1301 fire extinguishing devices, water spray fire extinguishing devices.
