Fire prevention measures cable fire prevention measures in order to prevent the cable fire accidents, the following precautions should be taken: (1) selection of cables meet the requirements of thermal stability. Optional cable, under normal circumstances, to meet the heating requirements of the long-term rated load, short circuit conditions, to meet the short-term thermal stability, to avoid overheating of the cable fire. (2) to prevent running overload. Cable run with a load, does not exceed the rated load, overload operation, should be strictly controlled cable overload operation time, so as not to overload heating cable fire. (3) comply with the relevant provisions of the cable laying. Cable laying should be kept away from heat sources, avoid steam pipe parallel or cross-arranged parallel or cross maintain the specified distance, and take insulation measures to prohibit cable laid in parallel across the board in the top or bottom of the heat pipe; in some pipeline tunnel or trench, generally avoid the laying of cables, laying insulation measures should be taken; overhead cable laying, especially plastics, rubber cables, insulation measures shall be installed to prevent heat pipe heat affected; cable laying, The cable between the cable and heat pipe and other piping, cable and roads, railways, buildings, etc. between the parallel or cross the distance should meet the provisions of the statutes;, cable dressing should be left waveform redundancy to prevent winter the cable stop running contraction excessive tension and damage the cable insulation. Cable turn should ensure that the minimum radius of curvature, to prevent excessive bending and damage the cable insulation; the cable tunnel should be avoided connector, due to the cable connector is the weakest areas of the cable insulation, cable joints prone to short-circuit fault, when in the tunnel installed in the middle joint, the application of fire-resistant partitions separated from other cables. The relevant provisions of the above cable laying to prevent the overheating of the cables, insulation damage fire play an effective role. (4) regular visits to check. Regular visits to check the power cable should regularly measure the air temperature in the cable trench and cable temperature should be prepared, especially large-capacity power cables and cable connector box temperature record. By checking to detect and deal with defects. (5) sealed cable hole, the hole and set fire doors and partitions. In order to prevent the cables from fire, you must all pass through walls, floors, shafts, cable trench and into the control room, cable mezzanine, control cabinet, instrument cabinet, switchgear, cables, etc. holes tightly closed (closed tight, smooth, beautiful, cable Do not injured). For longer cable tunnel and its bifurcation crossing should be set to the fire wall and fire compartment door. Under normal circumstances, the cable trench or hole on the door should be closed, so that the cable once the fire can be isolated or limit the combustion range, to prevent the spread of fire. (6) Remove the appearance of non-buried cable jute outer sheath. Buried cable appearance of a layer of immersion the jute protective layer of asphalt and the like, the cable buried to have a protective effect when the buried cable into the cable channel, tunnel, shaft, its appearance dip asphalt like jute protective layer stripped in order to reduce the danger of fire from expanding. Cable trench above cover should be covered, and cover the full, strong, the fire welding slag is not easy to fall into, to reduce the possibility of a cable fire. (7) Keep the cable tunnel cleaning and proper ventilation. Cable tunnel or channel should be kept clean, stagnant water and oils are not allowed to pile up garbage and debris, tunnels and trench should be promptly removed; should have proper ventilation in the case of normal operation, the cable tunnel and channel. (8) Hold the cable tunnel or channel with good lighting. Cable layer, cable tunnel or channel lighting is often kept in good condition, and up and down the tunnel and ditch crossing with a dedicated ladder, in order to run a check and cable fire fighting. (9) to prevent the kindling into the cable trench. Near the cable fire operations, measures should be taken to prevent the fire from entering the trench. (10) regular maintenance and testing. According to the rules of order and the actual situation of the cable runs, the cable should be regular maintenance and testing for timely processing defects and found latent failures, to ensure the cable safe operation and to avoid the occurrence of cable fire. Into the cable tunnel or channel within maintenance, test work should comply with the relevant provisions of the electrical safe work procedures.
