Description
Technical field
This utility model relates to a kind of fire-resistant high fire-retardance optical cable.
Background technology
Along with social development, the speeding up the construction of 4G, cloud computing etc., information carring capacity is increasing, the number of information processing
Capacity according to center is the most increasing, and information data center needs substantial amounts of transmission and the cable of equipment room interconnection, and manufactures this
Insulation and the sheath material of a little cables are mainly rubber and high molecule plastic polymer, and they majorities are easily to burn and prolong combustion
, due to the frequent generation of electrical fire accident, during the burning of these cables, toxic gas and dense smoke can be produced, grave danger people's
Life security, the fire-retardant problem of cable the most gradually causes the attention of countries in the world.
Utility model content
The purpose of this utility model is to provide a kind of fire-resistant high fire-retardance optical cable.
The technical solution adopted in the utility model is:
A kind of fire-resistant high fire-retardance optical cable, it is characterised in that: include cable core and the resistance being made up of center reinforcement, Loose tube
Water band, heat insulating belt, polyolefin jacket, polyolefin sheath, described some Loose tube centered by the reinforcement of center around twist in
On heart reinforcement, optical fiber is set in described Loose tube, some water blocking yarns are set outside the reinforcement of described center, described waterstop,
Polyolefin jacket, polyolefin sheath are coated on cable core the most successively, described waterstop and, arrange between polyolefin jacket
Heat insulating belt, arranges heat insulating belt or steel wire armor layer between described polyolefin jacket and polyolefin sheath.
The material of described Loose tube is low-smoke halogen-free polyolefin.
The material of described heat insulating belt is can porcelain Muscovitum.
The material of described polyolefin jacket is can porcelain low-smoke halogen-free polyolefin.
Described steel wire armor layer is zinc-coated wire.
The material of described polyolefin sheath is low-smoke halogen-free polyolefin.
Advantage of the present utility model: optical cable burns in fire and will not produce toxic gas and dense smoke, simultaneously can porcelain polyene
The ambient temperature that can intercept hydrocarbon and Muscovitum heat insulating belt passes to cable core affects proper communication, and can reach 500 DEG C in temperature by porcelain Muscovitum
More than can ceramic, temperature decrease when optical cable is amenable to fire-fighting fire extinguishing after ceramic, there is good shock resistance, it is ensured that
Communication is normal.

Detailed description of the invention
As shown in Figure 1, 2, a kind of fire-resistant high fire-retardance optical cable, including the cable core being made up of center reinforcement 1, Loose tube 3 with
And waterstop 4, heat insulating belt 5, polyolefin jacket 6, polyolefin sheath 7, some pine set 3 Guan Yi center reinforcements 1 centered by around
On Jiao Yu center reinforcement 1, optical fiber 2 is set in Loose tube 3, some water blocking yarns 8 are set outside center reinforcement 1, waterstop 4,
Polyolefin jacket 6, polyolefin sheath 7 are coated on cable core the most successively, waterstop 4 and, arrange between polyolefin jacket 6
Heat insulating belt 5, arranges heat insulating belt 5 or steel wire armor layer 9 between polyolefin jacket 6 and polyolefin sheath 7, the material of Loose tube 3 is
Low-smoke halogen-free polyolefin, the material of heat insulating belt 5 be can porcelain Muscovitum, the material of polyolefin jacket 6 be can porcelain low smoke and zero halogen gather
Alkene, steel wire armor layer 9 is zinc-coated wire, and the material of polyolefin sheath 7 is low-smoke halogen-free polyolefin.
This utility model optical cable burns in fire and will not produce toxic gas and dense smoke, simultaneously can porcelain polyolefin and Muscovitum
The ambient temperature that can intercept heat insulating belt passes to cable core affects proper communication, and can reach more than 500 DEG C in temperature and can make pottery by porcelain Muscovitum
Porcelain, temperature decrease when optical cable is amenable to fire-fighting fire extinguishing after ceramic, there is good shock resistance, it is ensured that communication is just
Often.
