Abstract
The invention discloses a reinforced type self-supporting optic fiber cable which comprises a supporting piece (1), a communication unit (2) and a hanging band (3) connecting the supporting piece (1) and the communication unit (2). The supporting piece comprises a plurality of reinforcing bars (1-1) and a first outer protective jacket (1-2). The communication unit (2) comprises a plurality of loose tubes (2-1), a central reinforcing piece (2-2), a wrapping band (2-3), a waterproof yarn layer (2-4) and a second outer protective jacket (2-5), a plurality of optical fibers and waterproof grease are arranged in each loose tube (2-1), the loose tubes (2-1) are twisted together around the outer side of the central reinforcing piece (2-2), and the wrapping band (2-3), the waterproof yarn layer (2-4) and the second outer protective jacket (2-5) wrap the outer side of the loose tubes (2-1) from inside to outside in sequence. The reinforced type self-supporting optic fiber cable has the advantages of being huge in tensile strength, good in waterproof effect, convenient to construct and mount and the like.
Description
Technical field
The present invention relates to a kind of optical cable, particularly relate to a kind of reinforced self-support cable.
Background technology
Along with the high speed development of the communication technology, the application of optical fiber is also more and more extensive, and in transmitting procedure, optical fiber is that the paving mode of optical cable in transmitting procedure mainly contains with the transmission of the form of optical cable: the setting up of high-altitude, the laying on ground and water-bed burying underground.
Common development pattern along with city and countryside, optical cable is universal also more and more wider in rural, but due to factors such as backroad facilities, it is exactly that set up in high-altitude that optical cable enters the most frequently used paving mode in rural area, traditional high-altitude is set up and is had a lot of unsafe factors, and, sometimes for the transmission of optical cable, need to hawser be set separately, increased difficulty of construction.Self-support cable is that the modal mode of using is set up in the cable high-altitude.
Chinese patent application number: 201120255964.2, a kind of self-support cable is disclosed, it comprises support member, support member connects suspender belt by one and connects an optical cable, and it is characterized in that: described optical cable is provided with oversheath, and the oversheath extension is connected with support member, described support member is comprised of steel wire and the sheath that is coated on the steel wire periphery, above-mentioned self-support cable installation is convenient, and conversion is simple, and structure arranges rationally.But its tensile strength is low, a little less than the ability to bear of support member, simultaneously, and in work progress, if the support member of cable damages and can't install, the cable that need to more renew, thus increased construction cost and workmen's workload.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of tensile strength large, good water-proof effect, the reinforced self-support cable of constructability and installation.
The objective of the invention is to be achieved through the following technical solutions: a kind of reinforced self-support cable, it comprises support member, the suspender belt of communication unit and connection support member and communication unit, described support member comprises a plurality of stiffeners and the first oversheath, described communication unit comprises a plurality of loose sleeve pipes, central reinforce member, band, layer and the second oversheath block water, in each loose sleeve pipe, be provided with multifiber and greasy for preventing water, a plurality of loose sleeve pipes are stranded around the outside of central reinforce member, band, block water layer and the second oversheath is coated on the outside of a plurality of loose sleeve pipes from inside to outside successively.
Described the first oversheath, suspender belt and the second oversheath are made by glass fiber reinforced plastics.
Described stiffener is many stranded the forming of steel wire.
Described loose sleeve pipe is PBT pine sleeve pipe.
Described central reinforce member is a kind of or its combination of aramid fiber, PEN material.
Described band and block water between layer and be provided with the aramid yarn winding layer.
The invention has the beneficial effects as follows:
In communication unit owing to having adopted by a kind of of aramid fiber, PEN material or central reinforce member and aramid yarn winding layer that it is combined into, thereby greatly strengthened the pull resistance of cable, make cable also can directly hang in the situation that support member damages;
2. oversheath and suspender belt adopt glass fiber reinforced plastics to make, and have strengthened the tensile strength of optical cable;
3. support member is inner adopts by the many stranded stiffeners that form of steel wire, has strengthened the ability to bear of support member;
4. greasy for preventing water and water blocking yarn can effectively stop the invasion of steam, make optical fiber be in water-less environment, have extended the serviceable life of optical fiber;
5. easy for installation, construction cost is low.
