How to do the flame retardant work of optical fiber cable

      Optical fiber cable In the process of transmission, because of heat or damage to the insulation layer, fire conditions are common. Optical fiber cable manufacturers teach you how to do fire and flame retardant work on cables.

     In order to fundamentally achieve the fire retardant of cables, optical fiber cable manufacturers must select suitable fire retardant materials during the production process. After technical and product identification, they should be designed according to design requirements and material use processes. Construction measures. The department using the cable can apply the fireproof coating on the cable. Pay attention to the uniform mixing of the paint and apply it along the direction of the cable. Determine the thickness, number of times and interval of the paint according to the requirements of the material.

     When wrapping the bag, pay attention to the tightness of the winding and the number of layers and thickness according to the instructions. After the wrapping is completed, it must be fixed at a certain distance. The sealing of the cable holes should also be strict and reliable, and no obvious cracks and voids should be formed. The larger holes should be filled with refractory linings and then blocked. The fire doors on the fire-resisting wall can not be ignored, and the holes should also be blocked; the cables on both sides of the fire-resisting wall should also be fire-proof tape or paint.
