Detailed description of the invention
Below by way of specific instantiation, embodiment of the present utility model being described, those skilled in the art the content disclosed by this specification can understand other advantages of the present utility model and effect easily. This utility model can also be carried out by additionally different detailed description of the invention or apply, and the every details in this specification based on different viewpoints and application, can also carry out various modification or change under without departing from spirit of the present utility model. It should be noted that, when not conflicting, following example and the feature in embodiment can be mutually combined.
It should be noted that, the diagram provided in following example only illustrates basic conception of the present utility model in a schematic way, then assembly that in graphic, only display is relevant with this utility model but not component count when implementing according to reality, shape and size drafting, during its actual enforcement, the kenel of each assembly, quantity and ratio can be a kind of random change, and its assembly layout kenel is likely to increasingly complex.
Referring to Fig. 1, optical fiber composite low-voltage cable (OPLC) is general all by the copper conductor 3 of insulation outer jacket 1, mutually insulated, the packed layer 3 between insulating outer protective cover 1 and copper conductor 3, and is placed in the fiber unit composition of inside. The difference is that, the novel optical fiber composite low-voltage cable that this utility model provides, do not include being embedded in fiber unit therein, but include: it is embedded with the micro-pipe 4 of insulation of pull rope 5, pull rope 5 for follow-up the optical fiber of connection led from the one end of micro-pipe 4 that insulate into, until the other end involves, to avoid amputating the copper conductor of length in reserve in existing construction, save precious metal and construction cost, it also avoid the problem that strong and weak electricity operation interface is unclear simultaneously. Preferably, for convenience of artificial traction, the length of pull rope 5 is more than or equal to the length of micro-pipe 4 that insulate.
Preferably, pull rope 5 is made up of Kafra fiber material, can pass through a tow attachment and be connected with optical fiber, it is ensured that being smoothed out of traction. The structure of tow attachment generally comprises the draw ring being connected with pull rope 4, and the optical fiber clamping part being connected can be reversed with draw ring, its area of section is less than the area of section of micro-pipe 4 cavity that insulate, making can be mobile in the micro-pipe 4 of insulation, and prevents the torsion in distraction procedure to be likely to the damage that optical fiber is caused. On-the-spot in cable construction, realize optical fiber by artificial tractive manner and import, easy and simple to handle, being bent the factors such as vertical run by insulation micro-pipe caliber tubular change little, micro-and OPLC affects little, it is not necessary to increase extra site operation equipment or specialized personnel.
Preferably, micro-pipe 4 that insulate is made up of thermoplastic macromolecule resin's material, and its inwall is shiny surface. Due to the pre-buried micro-pipe of insulation in the cable, cables manufacturing and laid processes will be born the lateral compression power of thousands of newton, so the material that high intensity is the pre-buried type micro-pipe of insulation selects firstly the need of the characteristic index considered. In the load operation of YJV type lv power cable, the hot environment of 90 DEG C inside cable, can be chronically at, the material temperature characteristic of the pre-buried type micro-pipe 4 of insulation, it is ensured that not soft viscous not indeformable under this temperature environment. In addition, OPLC requires that optical cable unit therein is non-fiber ointment type, the material behavior of micro-pipe 4 that insulate ensure that molding after inside pipe wall be smooth smooth, guarantee that the traction of follow-up field optical fibers and excess fiber length store smooth. It should be noted that macromolecule resin material in the present embodiment insulate, micro-pipe 4 has the anti-side of resistance to 120 DEG C of long term high temperatures and >=2000N/mm to the characteristic of extruding force, has reached the performance indications of metal coating armour pipe in outdoor type communications optical cable. Meanwhile, inside pipe wall light slip-stream is suitable, has reached the oil-filled cream pine set beam tube protected effect to more than 3 �� long optical fibers in existing outdoor type communications optical cable.
It should be noted that when novel optical fiber composite low-voltage cable of the present utility model includes the copper conductor 3 of many mutually insulateds, micro-pipe 4 that insulate is preferably the center between the copper conductor 3 being placed in many mutually insulateds, with uniform force, forms protection.
It should be noted that traction to the optical fiber of OPLC in the application is preferably tightly packaged fiber, including the emerald green type tightly packaged fiber in sea etc., there is high intensity, resistant to elevated temperatures characteristic, so that huge pulling force can be born in distraction procedure, further, it is possible to long-term work is in the hot environment of 90 DEG C.
Refer to Fig. 2; novel optical fiber composite low-voltage cable of the present utility model also includes a bundle pipes 6, can be made up of thermoplastic macromolecule resin's material, is used for placing the micro-pipe 4 of edge that thoroughly does away with to form isolation and protection more; to strengthen the density of laying of optical fiber, improve the utilization rate of bundle pipes pipeline.
In cable laying job site, it is possible to the forceful electric power operation first being completed this New O PLC by forceful electric power workmen by the construction maintenance mode of existing normal cable is installed, such as (once constructions) such as the stripping of cable socket and copper conductor joint installations. Then, light current workmen is by being embedded in this New O PLC to insulate the pull rope 5 of micro-pipe 4, grow more than the actual fiber unit that light path continues required, by the optical fiber of corresponding length by the one end of micro-pipe 4 that insulate lead into, the other end involves, until the length involved is the length that actual fiber unit needs reserve, to complete the installation maintenance work (secondary construction) of the light current operations such as fibre junction joint making.
In sum, novel optical fiber composite low-voltage cable of the present utility model, avoid in existing construction environment, the situation that exposed fiber unit is very easily impaired, decrease the waste of precious metal, reduce the construction cost of intelligent grid, simultaneously, meet the principle that strong and weak electricity operation separates, effectively overcome various shortcoming of the prior art and have high industrial utilization.
Above-described embodiment only illustrative principle of the present utility model and effect thereof, not for restriction this utility model. Above-described embodiment all under spirit of the present utility model and category, can be modified or change by any those skilled in the art. Therefore, art has all equivalence modification or changes that usually intellectual completes under the spirit disclosed without departing from this utility model with technological thought such as, must be contained by claim of the present utility model.
