Abstract
Disclosed is a highly waterproof and tensile optical fiber cable. The highly waterproof and tensile optical fiber cable comprises a central tensile part, optical fiber units, waterproof insulating buffer pipes, a water-blocking band, a glass fiber layer, a woven reinforcing layer and an insulating outer sheath, wherein the central tensile part is positioned in the center of the cable; the optical fiber units are distributed around the central tensile part; the waterproof insulating buffer pipes coat the corresponding optical fiber units respectively; the central tensile part and the waterproof insulating buffer pipes are coated with the water-blocking band; the water-blocking band is coated with the glass fiber layer; the glass fiber layer is coated with the woven reinforcing layer; the woven reinforcing layer is coated with the insulating outer sheath; and waterproof yarns, which extend in the longitudinal direction of the cable, are arranged between the waterproof insulating buffer pipes and the optical fiber units. Compared with the prior art, by adoption of the technical scheme, the waterproof performance of the optical fiber cable is improved due to the waterproof yarns; and by limiting the tensile strength of the waterproof yarns, the tensile performance of the optical fiber cable is further improved.
Description
Technical field
The invention belongs to fiber optic cables technical field, it particularly relates to a kind of height waterproof tensile optical fiber
Cable.
Background technology
The similar rope that cable is typically by several or several groups of wires (per group at least two) are stranded
Cable, mutually insulated between every group of wire, and be often twisted into around a center, whole outside is surrounded by height
The coating of degree insulation.It is erected at aerial more or is mounted in underground, the bottom, for telecommunication or power Transmission.
Wires and cables industry is the second largest industry that China is only second to automobile industry, product variety Service Efficiency and the country
Occupation rate of market is more than 90%.Worldwide, the Chinese electric wire gross output value has exceeded the U.S.,
Become the first big electric wire producing country in the world.
Electric wire is of many uses, and different use occasions are widely different to its performance requirement.Most of cable
Insulating materials, in addition to it must have higher insulaion resistance, dieletric strength or low dielectric loss, also
Good physical and mechanical properties must be taken into account, such as tension, counter-bending, anti-vibration, antitorque.
At present, with China's rapid development of economy and the increasingly raising of scientific and technological level, the consumption of cable is not
Disconnected to increase, the quality to cable is it is also proposed that higher requirement；But present general cable has shielding
Performance is high, strong, core is not firm enough for anti-dragging, waterproof is not enough and not environmentally etc. a series of asks
Topic；Such as cable adopts polythene material but polyethylene is for combustible material, containing halogen, once there is fire
Calamity, will discharge toxic gas, bring harm.
The content of the invention
In to solve the problems, such as background technology, the invention provides a kind of height waterproof tensile fiber optic cables.
The technical scheme is that：A kind of height waterproof tensile fiber optic cables, including central tensile part, light
The outer shield of fine unit, waterproof insulation separator tube, waterstop, glass layer, braiding enhancement layer and insulation
Set；Heart tensile members are located at cable center, and fiber unit is centrally located around tensile members, waterproof insulation
Separator tube wraps up fiber unit；Waterstop wraps up central tensile part and waterproof insulation separator tube, glass fibers
Dimension layer parcel waterstop, braiding enhancement layer parcel glass layer, insulating outer protective cover parcel braiding is strengthened
Layer；The water-blocking yarn along cable Longitudinal extending is provided between waterproof insulation separator tube and fiber unit.
As a kind of improvement, it is further provided between the central tensile part and waterproof insulation separator tube
Water-blocking yarn.
Further technical scheme is the present invention:The insulating outer protective cover inner side is provided with sheath dismounting rope, with
It is easily installed the fiber optic cables.
Further technical scheme is the present invention:The tensile strength scope of the water-blocking yarn is
10-140MPa, elongation percentage scope is 7-42%.
Further technical scheme of the invention is:The tensile strength of the water-blocking yarn is 120MPa,
Elongation percentage is 20%.
As a result of above-mentioned technical proposal, compared with prior art, the present invention is by arranging waterproof yarn
Line, improves the water resistance of fiber optic cables；By the tensile strength for limiting water-blocking yarn, further carry
The high tensile property of fiber optic cables.
