LED explosion-proof lamp line instructions

Explosion-proof light circuit description of the LED Editor: Shanghai Bao Lin explosion-proof 1, the location of the choice should be in the less explosive risk or far from the source of the laying of electrical lines. 2. Laying Mode Selection Explosion Hazard The electrical lines in the environment are mainly explosion-proof steel pipe wiring and cable wiring. 3、.Isolation Sealing When laying the channels of electrical lines and protective tubes, cables or steel pipes through partitions or floors between areas with different explosion hazard environments, tightly plug non-combustible materials. 4, the choice of wire material explosion hazardous area within the scope of the risk zone 1, the distribution line should use copper conductors or cables. Multiple stranded copper core cords or stranded copper core cables should be used where there is severe vibration. Aluminum core power cables must not be used underground in coal mines. Within the scope of Zone 2 of the Hazardous Degree of Explosion Hazard, the power lines shall use aluminum core conductors or cables with a cross-sectional area of ​​4 mm2 and above, and the illumination lines may use a cross-sectional area of ​​2.5 mm2. And above aluminum conductors or cables. 5. The selection of the section of insulated conductors and cable cross-sections in the zone 1 and zone 2 for current-carrying capacity shall be allowed. The allowable ampacity of the conductor shall not be less than 1.25 times the rated current of the fuse melt rated current and the breaker time delay overcurrent release. The allowable ampacity for the branch line leading to a low-pressure swash-type induction motor shall not be less than 1.25 times the rated current of the motor. 6. Electrical connections The intermediate connections of the electrical circuits in zones 1 and 2 must be internal to the explosion-proof junction boxes or splice enclosures that are compatible with the hazardous environment. Zone 1 should be flameproof junction box, and zone 2 can be increased safety junction box. When using aluminum core cables or conductors in the electrical circuit in Zone 2, it must be reliable so that the user can correctly install and repair it.
