When it comes to mining optical cables, many people know that mining optical cables are optical cables used underground in coal mines and are blue flame retardant sheathed optical cables. Mine fiber optic cable. But when it comes to coal safety certification, many customers do not know what kind of certificate this is. Safety certification is the abbreviation of coal mine safety certification. In 2007, the State Economic and Trade Commission and the Coal Mine Safety Supervision Bureau issued a number of documents to implement a safety production certification system for underground coal mining equipment, instruments, meters and other facilities, effectively preventing fake and shoddy products from entering the mine. Therefore, only the optical cable manufacturers with this kind of coal safety certification can produce and sell mining optical cables. Therefore, please identify the mining optical cable manufacturers with coal safety certification, and do not buy from informal channels. There is no after-sales guarantee.

In the past, I always thought that the color of the outer sheath of the mining optical cable determines the flame retardant coefficient of the mining optical cable, but later I learned that the sheath color of the mining optical cable is generally blue, and some manufacturers produce dark blue and some light blue. color, but this does not affect the flame retardant coefficient of the optical cable. The jacket of mining optical cable is generally blue PVC flame retardant jacket, and blue low smoke halogen free flame retardant jacket. The mining optical cables produced by optical cable manufacturers are Class A flame retardant, and all raw materials are brand new national standards.

Mining optical cable packaging is flexible packaging below 1000 meters, 2000 meters or 3000 meters full shaft packaging. Moreover, our optical cable manufacturer has a large number of mining optical cable models MGXTSV, MGTSV 4 cores, 8 cores, 12 cores and 24 cores in stock.
