Abstract
The invention provides a flame retardant optical cable which comprises a cable core and also comprises a first water blocking belt layer, a metal composite belt layer, a flame retardant inner protective layer, a second water blocking belt layer, a ceramic flame retardant composite belt layer, a steel plastic composite layer and a flame retardant outer protective layer which are orderly arranged outside the cable core. In order to prevent the cracking of a low smoke halogen free flame retardant polyolefin outer sheath, when the flame retardant optical cable is laid, the laying speed should be slowed down appropriately. The optical cable has excellent bending and compression performance and excellent flame retardant and fire resistant performance. The ceramic flame retardant composite belt arranged in the outer sheath is soft in a normal state, the bending performance of the optical cable is not affected, after the optical cable is laid, a hard ceramic shell can be formed to protect the optical cable. The smoothness of a line in a fire is ensured, the system failure of optical cable transmission is prevented, and the safety of life and property is protected to the maximum.
Description
Technical field
The invention belongs to optic cable design and manufacturing technology field, especially relates to a kind of fire-resistant resistance
Combustion optical cable.
Background technology
In the place that some are important, such as: megastore, theater, airport, skyscraper, hotel, in
Scheming rooms etc., for ensureing that communication line is intact, typically need to use the optical cable that fire resistance is higher.Once send out
Lighting a fire calamity, the optical cable that these places use can quickly be burnt scaling loss, causes the system mistake that optical fiber cable transmit
Imitate, and then flame-proof cable starts to be widely used.Further, traditional flame-proof cable occurs at optical cable
During fire, optical cable external protection sends toxic gas in combustion, so to increase casualties and
Property loss, is also unfavorable for the requirement of environmental protection simultaneously, additionally big fire in optical cable external firing time, it is impossible to
Intercept the heat outside optical cable very well, and then make cable interior heat raise, make fiber-optic transfer interrupt, enter
And make personal safety as well as the property safety increase further.Common fire-retardant cable structure mainly placed cloud in optical cable
Master tape, oversheath uses the sheath of low smoke and zero halogen.And in actual combustion test, although can be by single
Root testing vertical flammability, but the fire resistance test under stringent condition, common fire-retardant cable is then difficult to pass through.
The poor performance of material own causes insulating properties, bad mechanical property.

A kind of fire resistant flame retardant optical cable, including cable core, and cable core be orderly arranged outside each the first water blocking tape layer,
Metal composite belt, fire-retardant sheath, the second water blocking tape layer, ceramic fireproof composite tape layers, steel
Plastic composite strip layer and fire-retardant outer jacket.
Further, described cable core includes center reinforcement and the many Loose tube around center reinforcement,
All accommodate several fibers in every described Loose tube, and in Loose tube, be filled with fine cream.
Further, described optical fiber is colored optical fiber.
Further, described fine cream is thixotropy optical fiber filling paste.
Further, it is provided with cable core implant in described cable core.
Further, described cable core implant is the netted gasket for packing of PP or glass cord.
Further, described metal composite belt is plastic-aluminum combined belt or steel plastic compount belt.
Further, described fire-retardant outer jacket is low-smoke and halogen-free flame retardant polyolefin jacket.
Relative to prior art, the invention has the advantage that
1, this optical cable has good bending, compressive property, has excellent flame-retardant performance.?
The ceramic fireproof composite band arranged in oversheath, soft in normal state, do not affect optical cable
Bending property, after fiber cable laying, can form hard ceramic shell to protect optical cable as run into fire.Protect
Barrier circuit in case of fire unimpeded, prevents the thrashing of optical cable transmission, ensures to greatest extent
The safety of person property.
2, one layer of waterstop dry type material water-proof material of each layout outside cable core and sheath, had both reduced light
Cable weight, convenient transport and construction, produce complicated physical-chemical reaction when turn avoid ointment burning.
3. the steel plastic compount belt of oversheath is greatly enhanced the lateral pressure resistant ability of optical cable, and, fire-retardant outside
Sheath can use different colors, the convenient differentiation of optical cable under complex environment.
