Description
Technical field
The invention belongs to optoelectronic composite cable field, more specifically to a kind of fire resisting optoelectronic composite cable.
Background technique
Photoelectric composite low-pressure cable (abbreviation optoelectronic composite cable) determines the complexity of the construction of cable because of the diversity of its function
Property, but as long as there is reasonable structure design that can be better achieved and meet the function of composite rope, and meeting manufacturer's standard
While reduce manufacturing cost, realize the maximization of benefit.The structure of composite rope is usually by the cable core and sheath of layer-twisted type structure
Two large divisions is constituted.
Flame-proof cable still needs to keep good optical property after burning for a period of time at present.But this kind of optical cable due to
Prolonged calcination destroys, and will lead to optical fiber fragility fracture, and interrupt signal influences to communicate, or in fray-out of flame cooling procedure,
The contraction of cable surface material also results in optical fiber surface adhesive stress, damages optical fiber, thus make to transmit distorted signals or interruption,
Traditional optical cable, the universal measure for improving flame-retardant performance is the flame retardant property of enhancing protecting sleeve of optical cable, but due to optical cable
In there is also the non-flame resistant substances such as Loose tube, ointment, therefore it is difficult to ensure that optical cable high-performance refractory fire resisting, to affect light
Utilization of the cable in the higher occasion of some security levels.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of good flame retardation effects, can avoid the excessively high generation of fiber optic temperature
Damage is suitable for the higher occasion of security level.
To achieve the above object, the present invention provides the following technical scheme that a kind of fire resisting optoelectronic composite cable, from outside to inside according to
Secondary includes oversheath, composite steel band, fire-resistant isinglass belt and the sub- cable of optical fiber, and the sub- cable of optical fiber successively includes son shield from outside to inside
Set, sub- aramid fiber and optical fiber, are disposed with outer aramid fiber between the sub- cable of the optical fiber and fire-resistant isinglass belt.
Water blocking yarn is disposed with around the further sub- cable of optical fiber.
The further oversheath is low-smoke non-halogen flame-retardant oversheath.
The further sub- sheath is the sub- sheath of low-smoke non-halogen flame-retardant.
It further is disposed with the fire-retardant power supply line of ZBVR and CATV cable between the sub- cable of the optical fiber and fire-resistant isinglass belt,
The fire-retardant power supply line of ZBVR and CATV cable even circumferential are distributed in around the sub- cable of optical fiber.
The further composite steel band is two-sided composite steel band.
The fineness of the further outer aramid fiber is 3000D-7500D.
The further optical fiber is the counter-bending single mode optical fiber of G657A1.
Compared with prior art, the beneficial effects of the present invention are: the present invention is suitable for cable television signal and other electric power
The synchronous place of communication, optic communication, such as market, public square, ash Chang Zhongxin, advertisement large screen, with high flame resistance,
It when with flame, can prevent to burn first, secondly can delay the raising of temperature, to internal cable, power supply line and optical fiber
With good protection, even if after flame prolongs burning at the scene, also can be avoided the contraction damage optical fiber of material, guaranteeing good
Signal transmission.

Specific embodiment
The embodiment of fire resisting optoelectronic composite cable of the present invention is described further referring to Fig.1.
A kind of fire resisting optoelectronic composite cable successively includes oversheath 11, composite steel band 12,13 and of fire-resistant isinglass belt from outside to inside
The sub- cable 2 of optical fiber, the sub- cable 2 of optical fiber successively includes sub- sheath 21, sub- aramid fiber 22 and optical fiber 24 from outside to inside, in optical fiber
Outer aramid fiber 5 is disposed between cable 2 and fire-resistant isinglass belt 13.
Its neutron aramid fiber 22 and outer aramid fiber 5 are aramid fiber, are sheath there are also oversheath 11 and sub- sheath 21, " son " and
"outside" is to distinguish placement position.
Optical fiber 24 is set to most middle position in the present invention, saves the non-flame resistant substance such as Loose tube, ointment, using fire-retardant
Oversheath 11, sub- sheath 21, fire-resistant isinglass belt 13, sub- aramid fiber 22 and outer aramid fiber 5 are protected, and heat-insulated and fire resisting work is played
With, composite steel band 12 can play the role of structural support, avoid excessively bending, it can be avoided whole composite rope burning first,
Secondly heat is prevented quickly to be transmitted to inside, and aramid fiber has set, can either be multi-level fire-retardant and can inside and outside
Structural protection is constituted to optical fiber 24.
The present embodiment is preferably disposed with water blocking yarn 6 around the sub- cable 2 of the optical fiber, has the function of absorbing water and blocking water.
The present embodiment preferably the oversheath 11 be low-smoke non-halogen flame-retardant oversheath 11, the sub- sheath 21 be low cigarette without
