Fire prevention measures for overhead lines and indoor wiring

1. overhead lines

(1) in order to prevent pole collapse and disconnection, the maintenance of electric poles should be strengthened. Do not dig near electric poles or use electric power. However, the successful industrialization of a batch of new products in the industry will not affect users' use of tying livestock to poles

(2) if the overhead line crosses navigation, rivers and highways for hours, it shall be equipped with warnings to draw attention to the safety of passing vehicles and ships

(3) overhead lines shall not cross buildings and structures whose roofs are made of burning materials

(4) the fire prevention distance between the overhead line and the warehouse of class a goods, flammable and combustible, liquid storage tank, combustion supporting gas storage tank, flammable material storage yard, etc. shall not be less than 1.5 times the height of the pole; The fire separation distance from class a production plant emitting combustible gas shall not be less than 30m

(5) the distance between the side search line of overhead lines and buildings, the vertical and clearance distance between the search computer system and trees through Jinan assay controller line, and the distance between conductors of overhead distribution lines must comply with relevant safety regulations

(6) the trees near the electrical lines shall be pruned at regular hours to maintain sufficient safety distance and prevent accidents caused by branches flapping the wires

2. indoor wiring

(1) when the indoor line is designed and installed, the conductor type shall be correctly selected according to the environmental characteristics of the electrical equipment

(2) the exposed insulated conductor shall be protected from danger caused by insulation damage and shall be checked frequently during use. Maintenance

(3) when wiring, proper distance shall be kept between wires and between fixed points of wires

(4) in order to prevent mechanical damage, when the insulated conductor passes through the wall or the announcement shows combustible building components, it should pass through the insulated pipe built in the wall. Each pipe should only pass through one conductor. The distance between the outlet at both ends of the insulated pipe (porcelain pipe) and the wall should not be less than 10 mm. This can prevent the conductor from contacting the wall, so as to avoid the phenomenon of electric leakage caused by wet wall

(5) asbestos shall be used when laying wires along the surface of chimney, flue and other heating components. Glass fiber. Porcelain beads. Porcelain tubes, etc. are used as insulation to resist

(6) units with conditions should try to use flame-retardant wires and metal sleeves or flame-retardant plastic sleeves when setting indoor electrical lines
