A kind of divisional application of the application for a patent for invention of " reinforcement type central tube bundle cable ".
Technical field
The invention belongs to optical cable technology fields, and in particular to a kind of reinforcement type central tube bundle cable binder is reinforced
Type central tube bundle cable and preparation method.
Background technique
Optical fiber, abbreviation optical fiber are that the total reflection principle in a kind of light fiber made of glass or plastics transmits
Light conducts tool.Fine optical fiber is encapsulated in plastic sheath, allows it to be bent and be unlikely to be broken.The one of usual optical fiber
Light pulse is sent to optical fiber, the receiving device of the other end of optical fiber using light emitting diode or beam of laser by the transmitting equipment at end
Pulse is detected using photosensitive components.Cable comprising optical fiber is known as optical cable.Transmission loss due to light in optical fiber exists than electricity
The loss of electric wire conduction is much lower, and more because main production raw material is silicon, reserves are very big, is easier to exploit, thus it is cheap,
Optical fiber is promoted to be used as the media of information of long range.It is further with optic fibre manufacture process field and manufacturing equipment field
Optimization or development, existing fiber price further decrease, and optical fiber is improving rapidly in the total proportion of signal communication cable.Light
Cable is a certain number of optical fiber according to the certain way group stranding heart, is surrounded by sheath, some also cladding outer jackets, to realize light outside
A kind of communication line of signal transmission.With information-based development, the conveying capacity of information is increased rapidly, and optical fiber cable has obtained greatly
The application of amount.Cable configuration used at present is relatively simple, and this optical cable is by single tight tube fiber and to be coated on single fixed
The restrictive coating of optical fiber surface is constituted, and the production technology of this optical fiber is relatively simple, the bad mechanical property of optical fiber, is being constructed or is being used
It is easy to cause the bending of optical fiber in the process or fractures, eventually leads to the Transmission of optical signal, it is special to have seriously affected optical fiber transmission
The long-time stability of property.
Central-beam tube type fiber optic cable is inserted in optical fiber in the spiral space Loose tube being made by the plastics of high-modulus, in casing
Waterproofing compound is filled, applies one layer of material water-proof material and armoring material outside casing, two parallel steel wires are placed in two sides, and extrude poly-
Ethylene sheath stranding.Its main feature has: distinctive helicla flute Loose tube design is conducive to accurately control optical fiber excess length,
It ensure that optical cable has good mechanical performance and temperature characterisitic；Loose tube material itself have good anti-hydrolytic performance and compared with
High intensity is filled with extraordinary ointment in pipe, has carried out key protection to optical fiber.Two parallel steel wires guarantee that the tension of optical cable is strong
Degree.Small, light-weight, the easy laying of diameter.
In the prior art, the stability of armoring material is poor, easy to fall off, and the material of optical cable is easy to be damaged, and existing skill
The binder adhesive effect that the bonding of armoring material uses in art is bad, is often used in macromolecule in the raw material of conventional binder
The relevant binder of resin, and pe sheath is easy impaired aging.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of reinforcement type central tube bundle cable bondings
It is bad and poly- to solve central tube bundle formula cable armor layer adhesive effect for agent, reinforcement type central tube bundle cable and preparation method
The easily damaged problem of pvdf layer.
