Non-metallic Flame Retardant Optical Cable (MGTS53) for Loose Layer Stranded Coal Mine

The structure of MGTS 53 optical cable is that 250 µ m optical fiber is sheathed in a loose sleeve made of high modulus material, and the loose sleeve is filled with waterproof compound. The center of the cable core is a metal reinforced core, and for some number of optical cables, the metal reinforced core needs to be squeezed with a layer of polyethylene (PE). The loose sleeve (and packing rope) is twisted around the central reinforcing core to form a compact and circular cable core, with gaps in the cable core filled with water blocking filler. The inner cable core is formed by extruding polyethylene sheath after longitudinal wrapping of double-sided plastic-coated steel strip (PSP). Then protect a layer of double-sided plastic coated steel strip (PSP) sheath into cable. There are water blocking materials between the inner and outer sheaths. Wrap a layer of flame retardant sheath into cable.
