9 Measures to Prevent Fire of Wires and Cables
1. Ensure the construction quality, especially the production quality of the cable head must strictly meet the requirements.
2. Strengthen cable operation monitoring to avoid cable overload operation.
3. Cable test shall be carried out on schedule, and any abnormality found shall be handled in time.
4. The cable trench shall be kept dry to prevent the cable from being affected with damp, which may cause insulation degradation and short circuit.
5. Regularly clean the dust accumulated on the cable to prevent the self ignition of the accumulated dust from causing the cable to catch fire.
6. Strengthen regular calibration and maintenance of cable circuit switch and protection to ensure reliable action.
7. When laying the cable, keep enough distance from the hot pipe, and the control cable shall not be less than 0.5m; Power cable shall not be less than 1m. The control cable and power cable shall be arranged in separate trenches, layers and layers without overlapping.
