Abstract
The utility model relates to an optical cable casing, which is especially suitable for a 220kv and 66kv framework to lead a cable in. The optical cable casing is structurally characterized in that a plastic pipe is sheathed outside an optical cable, and a steel pipe is sheathed outside the plastic pipe; and the part of the optical cable, extending out of the steel pipe, is penetrated in a diameter changing thermoplastic pipe for sealing. The optical cable casing can solve the difficulty that water is accumulated in the optical cable casing, improves the running reliability of the optical cable, ensures the information smoothness of a power grid, saves the maintenance cost, avoids loss due to breakage of a communication cable, and ensures the safety running of the power grid.
Description
Technical field
The utility model relates to a kind of sleeve pipe, relates in particular to a kind of cable sleeve, is particularly useful for 220kv, 66kv framework leading in cable.
Background technology
Along with the develop rapidly of electrical network cause, the electric network information Communication Development is advanced by leaps and bounds, and the OPGW optical cable is overlapped in each transformer station, need be incorporated into the channel machine room to the optical cable on the framework with the ADSS optical cable more simultaneously.In the prior art, it is that the nylon plastic(s) pipe is worn optical cable through the logical machine room of cable conduit entering letter that framework draws the lower part.Optical cable is used the clay shutoff in nylon plastic(s) pipe exit, because of year in and year out, exposes to the weather; The plastic tube weathering, clay comes off, and meets the rainy day; Fill ponding in the nylon plastic(s) pipe, and winter colder area, behind the Water freezes into ice in the nylon plastic(s) pipe; As easy as rolling off a log freezing optical cable makes a big impact for so the normal operation of electrical network.
Summary of the invention
The utility model provides a kind of cable sleeve to the problem that exists in the above-mentioned prior art, has solved that cable sleeve is prone to ponding in the prior art, the problem that causes optical cable often to damage, and also the utility model improved reliability, provides cost savings.
The technical scheme of the utility model is following:
The outside suit plastic tube of optical cable, the outside suit steel pipe of plastic tube; The part that optical cable stretches out steel pipe penetrates the reducing thermoplastic tube and shuts.
The bottom of described plastic tube and steel pipe is a bend pipe.
The bottom of the bend of described plastic tube is provided with opening.
Described reducing thermoplastic tube is two-layer.
Be provided with glue-line between described optical cable and the reducing thermoplastic tube.
The utility model has the advantages of as follows:
The utility model has solved the difficult problem of cable sleeve ponding; The reliable rate of optical cable is improved; Guarantee the information opened of electrical network, simultaneously, saved expenses such as the manual work that each maintenance is in the past brought, material, vehicle; And avoided because the electric power netting safe running considerable economic benefit is given in other bigger losses that the telecommunication cable interruption is brought.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, optical cable, 2, plastic tube, 3, steel pipe, 4, the reducing thermoplastic tube, 5, opening.
Embodiment
The utility model, is described in detail as follows in conjunction with specific embodiment with reference to accompanying drawing.
Embodiment
With ￠ 40 steel pipes, the outside suit plastic tube 2 of optical cable 1, plastic tube 2 is sleeved in the steel pipe 3; The foundation bottom of plastic tube 2 and steel pipe 3 curves bend pipe according to landform; The bottom of plastic tube 2 bend with being sawn into road, three roads-four opening 5, has no injury to optical cable like this.The part that optical cable stretches out steel pipe penetrates double-deck reducing thermoplastic tube 4 and adds glue and shut.The optical cable exit can not intake after adding glue and shut with the reducing thermoplastic tube, can discharge automatically if under ground portion is permeable yet.
The protection domain of the utility model is as the criterion with claim, not limited by specific embodiment.
Claims (5)
1. cable sleeve is characterized in that the outside suit plastic tube of optical cable, the outside suit steel pipe of plastic tube; The part that optical cable stretches out steel pipe penetrates the reducing thermoplastic tube and shuts.
2. cable sleeve according to claim 1, the bottom that it is characterized in that described plastic tube and steel pipe is a bend pipe.
3. cable sleeve according to claim 2 is characterized in that the bottom of the bend of described plastic tube is provided with opening.
