Chống cháy nổ Shenhai
Explosion-proof electrical appliances typically involve enclosing a standard electrical device within an explosion-proof casing. Lớp vỏ này ngăn không cho khí và bụi nguy hiểm xâm nhập và phát ra tia lửa điện từ các sự cố điện bên trong. Những thiết bị này thường được sử dụng trong môi trường nguy hiểm, như nhà máy hóa chất, mỏ, mỏ dầu, nền tảng ngoài khơi, và trạm xăng, where national regulations mandate the use of explosion-proof equipment.

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. Ví dụ, 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. Hơn thế nữa, 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.
