Описание

The cable is made by the tight buffer fiber wrapped with a layer of aramid yarn as strength member units,multi fibers as the sub unit twist with FRP into the circle ,and finally into fiber optic cable with PVC or LSZH sheath,with dry-type water-blocking materials between fiber and sheath.

Функции

– Each sub cable contains aramid yarn,good bend performance,without loose tube,cleaning friendly,easy construction and connection.
– Tight buffer fiber with single strength member and sheath to overcome the effect from bad environment and Mechanical stress.
– The low smoke and low halogen flame retardant sheath has the characteristics of fire prevention and self extinguishing, and is suitable for indoor environment such as computer room, cable shaft and indoor wiring.
– LSZH sheath,UV,Waterproof mildew,ESCR,No acid gas release,non-corrosive room equipment, suitable for indoor and outdoor use or need a high flame-retardant grades of the indoor environment (such as wiring in the ceiling, open wire cabling etc.)
