Product description
GYFTZY (non-metallic strengthening member, flame retardant, loose tube layer-stranded filling type, polyethylene sheath) non-metallic flame-retardant optical cable (general power optical cable adopts layer-stranded type) is basically the same as in GYFTY, mainly based on GYFTY optical cable The increase of the sheath considers its flame retardancy. The center reinforcing member adopts a glass fiber reinforced plastic rod (FRP) with a higher Young’s modulus. The double-sided film-coated corrugated steel tape is longitudinally wrapped and tightly bonded with the PE sheath, which not only ensures the radial moisture resistance of the optical cable, but also enhances the cable’s ability to withstand lateral pressure.
Features
●Reasonable design and control of the excess length of the optical fiber in the loose tube, so that the optical cable has excellent tensile performance and temperature performance
●The cable core is filled with grease to ensure the longitudinal water blocking effect
●The whole cable is non-metallic, free from electromagnetic interference
●The sheath is made of low-smoke, halogen-free, flame-retardant polyethylene, which can be used in entry and tunnels.
Applicable laying
Power system, heavy lightning and places with severe electromagnetic interference
