Abstract
The utility model relates to a self-supporting overhead anti-bird pecking photoelectric hybrid cable with similar performance when compared with a normal photoelectric composite cable; the self-supporting overhead anti-bird pecking photoelectric hybrid cable comprises aluminium conductors, a red PE polyethylene sheath layer, PBT loose tubes, a metal reinforcement member, a steel strand, a PE inner sheath, a metal composite belt, and red PE sheath material; fibers are protected by loose sleeves to form PBT loose tubes filled with fillers; the PBT loose sleeve tubes are twisted around the metal reinforcement member to form a cable core; the longitudinal wrapping armoring metal composite belt is wrapped outside the cabled cable core; the red PE sheath material is arranged outside the armored metal composite belt; the aluminium conductors, the steel strand, the PE inner sheath are arranged in parallel in the red PE polyethylene sheath layer; and the inner sheath cable, the aluminium conductors (1), and the steel strand are arranged in the sheath in a shape of a number 8. The outer sheath layer employs the red PE sheath material to effectively prevent bird pecking, and can resist solar radiation.
Description
Technical field
The utility model relates to the optical cable technology field, and it is the anti-unfirmly closing photoelectricity composite cable of a kind of Self-bearing-type overhead in definite saying.
Background technology
The multiplex copper conductor of photoelectric mixed cable on the market, electric conductivity is better, has but that cost is relatively high, a Heavy Weight, the relatively poor shortcoming of bending property.Cost is low, lightweight, the advantage of good bending property and Self-bearing-type overhead aluminium core mixing cable has; The PE outer jacket is that red polyethylene sheath material effectively prevents unfirmly closing, and can resist solar radiation.But in use also there are some drawbacks.Have ointment such as loose sleeve pipe in construction and drop onto contaminated environment on the ground, the optical fiber in the loose sleeve pipe needs could use behind the fusion splice, affects the engineering time; Aluminium core conduction loss is large, bad welding.
Summary of the invention
The purpose that the utility model solves provides the anti-unfirmly closing photoelectricity composite cable of a kind of Self-bearing-type overhead, is used for that workout cost is relatively high, Heavy Weight, the relatively poor problem of bending property.
The technical solution of the utility model is: Self-bearing-type overhead is prevented unfirmly closing photoelectricity composite cable, it comprises aluminum conductor, red PE pe sheath layer, PBT pine sleeve pipe, metal reinforcement, steel strand wire, PE sheath, metal compound belt, red PE protective cover material, it is characterized in that: carry out the protection of pine cover behind the optical fiber coloring and make PBT pine sleeve pipe, be filled with filler in the PBT pine sleeve pipe; Through stranded PBT pine sleeve pipe and metal reinforcement are made cable core, coat laggard row metal composite belt longitudinal bag armouring by waterstop, protect at last in forming behind the metal compound belt armouring and carry out outer protecting by red PE protective cover material.At last will in protect, aluminum conductor, steel strand wire, PE sheath, row is installed in the red PE pe sheath layer.In protect cable, aluminum conductor, steel strand wire and be arranged into 8 font sheaths.It is in order effectively to prevent unfirmly closing that outer jacket uses red PE protective cover material, and can resist solar radiation.
Advantage of the present invention is can reduce cost, weight reduction, prevent unfirmly closing, the opposing solar radiation.
The series of problems that 1, generally could solve with many cables can mix cable with one at this and replace;
2, low, the weight saving of cost, be easy to built on stilts laying;
3, can satisfy long Distance Transmission, also sectional uses;
4, the physical characteristic that still keeps optical cable is such as anti-collapse, stretching etc.;
5, client's purchase cost is low, and operating expenses is low, and the networking expense is low;
6, have superior bending property and good anti-side pressure performance, easy construction;
7, red polyethylene sheath material effectively prevents unfirmly closing, and can resist solar radiation;
8, provide simultaneously multiple transmission technology, strong with adaptability height, the extensibility of equipment, product is widely applicable;
9, provide huge bandwidth access, guarantee the remote power feeding demand;
10, save cost, optical fiber as the usefulness of reserving to the family, has been avoided the secondary wiring;
11, solve equipment electrical problem (avoiding repeating to lay supply line) in the networking;
12, according to ports such as customer requirement FC/SC/ST.
Production process:
1, optical fiber pine cover coating
For not being subjected to external action, protection optical fiber outside optical fiber coating, do not squeeze into the suitable plastics pine cover of one deck and the process of filled composite resilient coating.
2, aluminum conductor insulating barrier sheath
The insulating material isolation will be arranged between the insulated electric conductor.Otherwise this wire rod just can not use.Our employed main insulating material is 5300E, utilizes extruder to finish aluminum steel surface sheath.
3, stranding
Stranded to together with loose sleeve pipe, presumable gasket for packing, reinforcement nature, excessive for preventing yarn-binding tension, be adjusted to inertial states, purpose be element is closed as a whole.
4, inner sheath
Cable core behind the stranding is carried out the vertical bag of metal compound belt armouring, carry out outer protecting by the PE protective cover material at last.
5, oversheath
In protect cable, aluminum conductor, steel strand wire and be arranged into 8 font sheaths.The restrictive coating of optical cable is to protect the impact that cable, steel strand wire, aluminum conductor are avoided extraneous mechanism and environmental condition in protecting, and we can select different sheath materials according to customer requirement.

Embodiment
Self-bearing-type overhead is prevented unfirmly closing photoelectricity composite cable, it comprises aluminum conductor, red PE pe sheath layer, PBT pine sleeve pipe, metal reinforcement, steel strand wire, PE sheath, metal compound belt, red PE protective cover material, it is characterized in that: optical fiber carries out the protection of pine cover and makes PBT pine sleeve pipe 3, is filled with filler in the PBT pine sleeve pipe 3; Through stranded PBT pine sleeve pipe 3 is centered around outside the metal reinforcement 4, cable core behind the stranding is outward the metal compound belt 7 of vertical bag armouring, the outside is that red PE protective cover material 2 is housed behind metal compound belt 7 armourings, the red PE pe sheath layer 2 of aluminum conductor 1, steel strand wire 5, PE sheath 6, they are installed in the red PE pe sheath layer 2 side by side.In protect cable, aluminum conductor 1, steel strand wire 5 and be arranged into 8 font sheaths.Metal compound belt 7 is equipped with waterstop 8.
During production, at first with the protection of optical fiber pine cover, aluminum conductor surface jacket insulation material; Make reinforcement and loose sleeve pipe and presumable gasket for packing with steel wire again and be twisted into cable core, carry out the PE sheath behind the cable core composite band armouring, finish in the cable core and protect; Will in protect optical cable, aluminum conductor, steel strand wire and become finished product behind the 8 font sheaths.Performance is identical with photoelectric mixed cable with Access Network, and different is that Self-bearing-type overhead photoelectric mixing cable is easier to built on stilts laying, and cost is low, lightweight, prevents unfirmly closing, the opposing solar radiation.
