Fire safety measures for the cable fire prevention measures in order to prevent the cable fire accidents, the following precautions should be taken: (1) selection of the cables meet the thermal stability requirements. Optional cable, under normal circumstances, can meet the requirements of long-term rated heating load, and under short circuit conditions, to meet the short-time thermal stability, to avoid cable overheat and catch fire. (2) prevent the running overload. Cable with load running, generally do not exceed the rated load operation, if overload operation should strictly control cable overload running time, so as not to overload heating cable fire. (3) comply with the relevant provisions of the cable laying. Cable laying should be as far as possible away from heat, avoid steam pipe parallel or cross arranged parallel or cross should remain the required distance, and take the heat insulation measures prohibit cable across the board parallel laying in the top or bottom of the heat pipe; in some the pipe tunnel or trench, generally avoid laying cable For laying insulation measures should be taken; overhead cable laying, especially plastics, rubber cables, shall be employed to prevent the impact of heat pipes and other thermal insulation measures; cable laying parallel or cross the distance between the cable between the cable and heat pipes and other pipes, cables and roads, railways, buildings, etc. should meet the provisions of the statutes; addition, cable dressing should be left to the waveform redundancy in case The winter cable stop running contraction excessive Rally damage the cable insulation. The cable turn should guarantee a minimum radius of curvature to prevent excessive bending damage the cable insulation; cable tunnel should be avoided connector, cable connector is the weakest cable insulation joints prone cable short-circuit fault, when the tunnel installed in the middle connector, the application of fire-resistant partition separated with other cable. Play an effective role in the relevant provisions of the above cable laying to prevent overheating of the cables, insulation damage fire. (4) regular visits to check. The power cables should be inspected regularly by check periodically to measure the temperature of the air in the cable trench and cable temperature, especially in large-capacity power cables and cable connector box temperature record should be prepared. 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 must all across the walls, floors, shafts, cable trench into the control room, cable sandwich, control cabinets, instrument cabinets, switchgear, etc. cable holes tightly closed (closed tight, smooth, beautiful, cable Do not injured). The longer cable tunnel forked crossing should set the fire wall and fire doors. Under normal circumstances, the the the cable ditch or hole on the door should be closed, so that cable once the fire can isolate or restrict burning range, to prevent the spread of fire. (6) stripped the buried cable appearance jute outer sheath. Appearance of buried cable layer dip the asphalt like jute protective layer, the protective effect of the cables in direct burial ground, buried cable into the cable trench, tunnel, shaft, and its appearance Baptist the asphalt like jute protective layer should stripped, to reduce the danger of fire from expanding. The same time, the cable channel above the cover should be covered, and cover the full, sturdy, welding fire slag is not easy to fall into, to reduce the possibility of a cable fire. (7) maintain a clean and proper ventilation of the cable tunnel. Cable tunnel or channel should be kept clean and not allowed to pile up garbage and debris, tunnel and trench hydrocephalus and integrated oil should be promptly removed; should have proper ventilation in the case of normal operation, the cable tunnel and channel. (8) to keep the cable tunnel or channel with good lighting. The 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) prevent the kindling into the cable trench. Near the cable fire operations, measures should be taken to prevent kindling into the trench. (10) periodic maintenance and testing. Actual situation according to the rules of order and the cable run, the cable should conduct regular maintenance and testing, in order to deal with the defects and found a potential fault, to ensure the the cables safe operation and avoid cable fire occurred. Into the cable tunnel or channel maintenance, testing, and should comply with the relevant provisions of the electrical safety regulations ".
