GYTZA53 Loose layer stranded armored flame-retardant optical cable
The colored optical fiber is placed in a loose tube made of high modulus hydrolysis resistant material, and the tube is filled with water-blocking fiber paste to form an optical fiber loose tube. A plurality of optical fiber loose tubes arranged according to the color sequence requirements and possible fillers surround the central metal reinforced core, and the cable core is formed by SZ twisting. Outside the cable core, double-sided plastic-coated corrugated aluminum tape is longitudinally wrapped, and the gap between the cable core and the aluminum tape is filled with water-blocking cable paste. PE/LSZH inner sheath was extruded after longitudinal wrapping of corrugated aluminum strip, then flame retardant sheath was extruded after longitudinal wrapping of corrugated steel strip coated with plastic on both sides, and water-blocking cable paste was filled between the inner sheath and corrugated steel strip.
