Abstract
The utility model relates to a double-layer steel-tape armored rodent-resistant cable. The technical problem to be solved is to provide an improved cable. A timer can effectively prevent rat eating and white ants and has the characteristics of flame retardance, fire resistance and nontoxicity. The technical scheme is that: a double-layer steel-tape armored double-sheathed reinforced rodent-resistant cable comprises an outer layer sheath, an inner layer sheath, a reinforcing core coated by the inner layer sheath and a beam tube, wherein a first steel tape layer and a water-resistant yarn fastening band are arranged between the beam tube and the inner layer sheath. The cable is characterized in that: a second steel tape layer is also arranged between the inner layer sheath and the outer layer sheath; the winding direction of the second steel tape layer is opposite to that of the first steel tape layer; the reinforcing core is a nonmetallic reinforcing core; a gap between beam tubes is filled with water-resistant cable grease; and each beam tube comprises 2 to 12 optical fibers.
Description
Technical field
The utility model relates to a kind of optical cable, is specifically related to a kind of double-deck steel-tape armouring rodent-resistant cable.
Background technology
Advantages such as fiber optic cable communications have that capacity is big, transmission range length, anti-electromagnetic interference (EMI), good confidentiality, line footpath are little, in light weight, aboundresources, spread to custom system gradually, replace the traditional circuit that can't realize the wideband information transmission in the custom system in the past, can provide new business such as high-quality television image and high-speed data, to satisfy people's life and professional needs.Lightguide cable link is the pith that optical fiber telecommunications system is formed, and the construction quality of lightguide cable link is a key of guaranteeing that optical communication system is functional and steady in a long-term.
The plastic jacketed cable of outdoor laying, optical cable suffer nibbling of mouse, termite through regular meeting; cause every year many accidents to take place; cause tremendous loss economically; the outside run optical cable adopts one deck steel-tape armouring to add the structure (ribbon spiral shape is wrapped on the periphery of optical cable) of sheath more for this reason; but in actual use; some areas are more serious because repeat the situation of nibbling, and cause the individual layer steel band can't guarantee cable core safety.In addition along with increasing that optical cable uses, and much all be bunchy be laid in together, in case catch fire, may cause serious economy loss even casualties.
The utility model content
The purpose of this utility model is to overcome the deficiency that the above-mentioned background technology exists, and a kind of improvement of optical cable is provided, and this timer should be able to effectively be prevented rat eaten, termite-proof, and has fire-retardant, fire-resistant, nontoxic characteristics.
The utility model proposes following technical scheme:
The two reinforced rodent-resistant cables of sheath of double-deck steel-tape armouring comprise outer protective sleeve, internal layer sheath, by strengthening core and beam tube that the internal layer sheath is wrapped in, are provided with the ground floor steel band and the bundle cotton yarn tape that blocks water between described beam tube and the internal layer sheath; It is characterized in that: also be provided with second layer steel band between described internal layer sheath and the outer protective sleeve.
Described second layer steel band is opposite with the winding direction of ground floor steel band.
Described strengthening core is nonmetal strengthening core.
Be filled with the cable cream that blocks water in the gap between the described beam tube.
Described beam tube includes 2～12 optical fiber.
The beneficial effects of the utility model are: the utility model is being set up one deck steel band (i.e. second layer steel band between outer protective sleeve and internal layer sheath) on the basis of conventional optical cable; the two-layer steel band oppositely steel band of parcel makes optical cable be protected fully; can effectively prevent optical cable by the damage of nibbling of mouse, termite, even and under the situation of construction wrong damaged phenomenon also obviously reduce than conventional optical cable.In addition, protection against the tide of the present utility model, moisture-proof characteristic are good, also have good weather resistance, flame-retardant performance, toughness, wearing quality and extremely excellent mechanical and physical performance.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
The two reinforced rodent-resistant cables of sheath of double-deck steel-tape armouring as shown in Figure 1 are followed successively by outer protective sleeve 1, internal layer sheath 3, ground floor steel band 4 from the inside to the outside, block water and prick cotton yarn tape 5, prick strengthening core 7 and the beam tube 6 (being 6 beam tubes shown in the figure) that cotton yarn tape is wrapped in by blocking water.Strengthening core is positioned at the optical cable center, and beam tube and strengthening core are arranged in parallel; Be filled with the cable cream that blocks water in the gap between beam tube and the strengthening core; Described beam tube (Figure 1 shows that the multi-core fiber beam tube) comprises loose sleeve pipe and is wrapped in 2 ~ 12 fibre cores by loose sleeve pipe, is filled with fine ointment in the gap between the fibre core.Above-mentioned is the structure of conventional optical cable.
The utility model has been set up second layer steel band 2 on the basis of conventional optical cable, described second layer steel band is between internal layer sheath and outer protective sleeve, the winding direction of the winding direction of second layer steel band and ground floor steel band opposite (one deck steel band twines around the clockwise spirality of optical cable axis and coats, and another layer steel band twines around the counterclockwise spirality of optical cable axis and coat).
Described strengthening core is nonmetal strengthening core or strengthens rope.
Described outer protective sleeve adopts the low-smoke halogen-free polyolefin material to make, and the internal layer sheath adopts polythene material to make, and therefore the utlity model has good fire prevention, humidity resistance; After setting up second layer steel band, can effectively prevent the situation generation that optical cable is nibbled and damaged by mouse, termite.
