Fire prevention measures in order to prevent the cables cable fire fire accidents, should take the following precautions: (1) selection of thermal stability to meet the requirements of the cable. Optional cables, under normal circumstances, be able to meet long-term requirements of the rated load fever, under short circuit conditions, to meet short-term thermal stability and avoid overheating of the cables on fire. (2) to prevent run-off load. Cable run with a load, generally does not exceed the rated load operation, if the overload operation, should be strictly controlled cable overload running time, so as not to overload the cable fire heating. (3) comply with the relevant provisions of cable laying. Cabling should be as far away from sources of heat, avoid steam pipes are arranged parallel or crossover, if parallel or crossed, should maintain a predetermined distance and take insulation measures to prohibit the cables laid in parallel across the top or bottom heat pipe; pipe in some tunnel or trench, generally avoid the laying of cables, for laying insulation measures should be taken; overhead cable laying, especially plastics, rubber cables, should prevent the effects of heat pipes and other thermal insulation measures; cable laying, cable between the cable between heat pipes and other pipes, cables and roads, railways, buildings, etc. The distance between the parallel or cross should meet the Statutes; addition, cable wrap should be left waveform redundancy to prevent winter Cable stop running excessive shrinkage tension and damage the cable insulation. Cables should guarantee a minimum bend radius of curvature, to prevent excessive bending and damage cable insulation; cable connector tunnel should be avoided, because the cable connector is insulated cable weakest areas, cable joints prone to short-circuit fault, when it is necessary in the tunnel middle connector is installed, the application of fireproof bulkhead separates it from other cables. Relevant provisions of the above cable laying cables to prevent overheating, fire insulation damage are an effective role. (4) regular visits to check. Regular inspections of the power cable should be checked periodically measure the air temperature in the cable trench and cable temperature, in particular, to make large-capacity power cables and cable connector box temperature records. By checking to detect and deal with defects. (5) tightly closed cable hole, holes and setting fire doors and walls. In order to prevent the cables from fire, must all pass through walls, floors, shafts, trenches and into the control room, cable mezzanine, control cabinets, instrument cabinets, switchgear, etc. The holes for the cable tightly closed (closed tight, smooth, beautiful, cable Do not suffer injury). For longer cable tunnel and its bifurcation crossing should be set to fire wall and fire compartment door. Under normal circumstances, the cable trench or hole in the door should be closed, so that the cable once the fire burning can be isolated or limit the scope, to prevent the spread of fire. (6) Non-buried cable stripping outer sheath outer jute. Buried Cable looks like a layer of jute soaked asphalt protective layer, buried in the earth cable has a protective effect, when the buried cable into the cable trenches, tunnels, silos, it looks like the jute soaked asphalt protective layer should be stripped, to reduce the risk of fire from expanding. Meanwhile, the cable trench cover above should be covered, and cover the full, robust, easy to fall into the slag welding fire, reducing the likelihood of occurrence of the cable fire. (7) to keep the cable tunnel cleaning and proper ventilation. Cable tunnel or channel should be kept clean inside, not allowed to pile up trash and debris, tunnels and trench water and product oil should be promptly removed; under normal operating circumstances, cable tunnels and the channel should be adequate ventilation. (8) to keep cable tunnels or channels with good lighting. Cable layer, cable tunnels or channels within the lighting kept in good condition, and the need to ditch crossing tunnels and up and down a ladder with a dedicated, in order to run a check and cable fire fighting. (9) into the cable trench to prevent fire. Near the cable fire operations, should take measures to prevent fire entering the trench. (10) regular maintenance and testing. Cable runs by rules of order and the actual situation of the cable should be regularly inspected and tested in order to discover latent defects and timely processing failures, to ensure safe operation and to avoid cable cable fires. When entering the cable within the channel tunnel or overhaul, experimental work, observe the "electrical safety regulations" the relevant provisions.
