Explosion-proof electrical appliances typically involve enclosing a standard electrical device within an explosion-proof casing. Ин корпус аз ворид шудани газҳои хатарнок ва чанг ва шарора аз норасоиҳои дохилии барқ пешгирӣ мекунад. Ин дастгоҳҳо одатан дар муҳити хатарнок истифода мешаванд, монанди заводхои химиявй, минаҳо, конхои нефть, платформаҳои оффшорӣ, ва станцияхои газ, where national regulations mandate the use of explosion-proof equipment.
Стандартҳои бехатарӣ:
Manufacturers of explosion-proof electrical appliances must possess various certifications, including explosion-proof qualification certificates and production permits. For export and certain industries, additional certifications are necessary. Масалан, marine explosion-proof appliances must have CCS certification from the classification society. When exporting to other countries, certifications like the American ABS and European ATEX are often required. Гайр аз ин, large domestic and international petrochemical companies demand their network certificates, such as those from Sinopec, CNOOC, and CNPC. The explosion-proof industry has numerous relevant certifications, and the issuing authority of these certificates is crucial, with more authoritative being better.
