It can require.
Currently, the communications optical cable of low-smoke non-halogen flame-retardant oversheath, has certain fire resistance, but fire resistance grade is very
Low, since halogen-free low-smoke flame retardant material can also burn in flame, optical cable can only continue the fire resistance of a few minutes, cannot
Guarantee in thermal-flame (850 DEG C or more) last longer.
Optical fiber cable is used not only for communicating, it is often more important that transmits for data, data acquisition, security control, image pass
Defeated equal various functions.Therefore, once occur fire behavior wish optical cable can continue the larger time fire resistance (such as: 90 minutes and with
On), guarantee that the data transmissions of related setting continue for some time, the optical cable of current low-smoke non-halogen flame-retardant oversheath is difficult to carry on a shoulder pole
When this performance requirement.
Utility model content

Layer.
Further, the fiber unit containing refractory protection includes: that optical fiber, fiber paste, nonmetallic Loose tube and Loose tube are resistance to
Fire bed, Loose tube flame retardant coating are arranged and are connected to the outer wall of nonmetallic Loose tube.
The usefulness of the utility model: pass through the flame retardant coating of optical fiber loose tube protection, three layers of fire resistance of cable core
Protection, has been effectively ensured flame-proof cable in thermal-flame (850 DEG C or more) last longer (90 minutes or more), it is ensured that resistance to
Flame cable can guarantee optical cable steady operation in the long period when fire behavior occurs.
