Explosion proof explosion-proof certified by the state authorities, in full accordance with the national explosion-proof standards, Hebei proof lighting, proof the highest level, can work safety in explosive areas. Use energy-efficient light high-intensity gas-discharge light source, high luminous efficiency, high color rendering, soft lighting, illumination uniformity, the average life of up to 55,000 hours; CRI> 90. Introduced directly into the cable and wire connections direct access to the main housing. It is worth noting that the explosion-proof lighting specifications, seals aging or pressure without tight situation can directly burn or booster. Accordingly, dangerous sparks during normal operation, arcs or dangerous temperatures and the housing volume greater than 2000cm3 or GB3836.1 "explosive gas atmospheres Electrical Equipment Part 1: General requirements" on four classified as ⅡC level proof lighting, unsuitable elastic ring compression type direct introduction. Although this does not explain GB3836.2, GB3836.15-2000 "explosive gas atmospheres Part 15 Electrical equipment: Hazardous areas electrical installation (other than mines)" shows the sealing member and transparent framework provisions can refer a) of type. Structurally, explosion-proof lighting wholesale, should be subject to the transparent member (internal explosion) force is transmitted directly to the metal shell, and then transferred to the metal housing is inappropriate transparent member or plate and screws, at the same time, Direct proof lighting, transparent pieces not subjected to stress after installation, so as to ensure a transparent and reliable member and housing combined. Proof lighting selection, installation, use and maintenance are explosion-proof lamps guarantee long-term security, reliable, and efficient work indispensable part, must be sufficient attention.
