The invention provides the laying method of a kind of optical cable and cable,
Its cable lays general provisions:
Cable lays must be complete in constructions such as its spool routeing, crane span structures, and can carry out after acceptance(check).Cable to the spool mouth of pipe, the section of crane span structure and may be caused injury region to carry out protective treatment before laying in cabling processes by cable；It is then determined that cable is laid to each end again in the position that cable disc, line case are placed.
Including step: laying of horizontal distribution and laying of vertical main line.
Specifically include:
Laying of horizontal distribution:
1, draught line is penetrated spool.The steel wire that draught line selects rigidity, toughness is moderate, and during construction, traction the end of a thread pliers is curved rounded diamond shape, short diagonal length L is not more than 2/3 (see the accompanying drawing 1) of spool internal diameter D.When draught line the end of a thread arrives spool turning or is obstructed, stir in rear end around action, make traction the end of a thread be rotationally advancing in managing online, draught line can be allowed to pass through turning.
2, traction horizontal cable.When laying in spool, if cable is directly banded together by unit cable with draught line electrical adhesive tape；If multi-cable draws together, the most first the termination of cable neat electrical adhesive tape are bundled into a branch of, binding distance about 50mm～100mm, then catches at cable binding with draught line, more smooth to draught line and bunch of cables is banded together with electrical adhesive tape；Last at the uniform velocity dragline lead terminal, by cable laying in pipe.When laying in horizontal crane span structure, first multi-cable head neat electrical adhesive tape are bundled into a branch of, then tie up once every 0.5m～1m, tie up 3～4 times, tie up length 2m～3m；Then at every 3m～5m of crane span structure straightway and at turning, threeway, distribution workmen wears power transmission cable in crane span structure.
Laying of vertical main line:
1, the laying of big pair count cable, is used the form of construction work of " downward lowering ", big pair count cable dish is both positioned over telecommunication closet or the equipment room of higher level, is laid downwards by vertical crane span structure.In laid processes, first by supporter, cable disk is erected, then drawn downwards by fixed pulley and lay (see figure accompanying drawing 2).So lay, it is ensured that cable does not produce knob in laid processes and rolls up the phenomenon looped, and effectively prevents cable from being dragged, rubs, scrapes, grinds equivalent damage, thus improves cable laying quality, reduces hidden danger.
2, the laying of optical cable, the same form of construction work using " downward lowering ", due to the particularity of the material of optical cable own, so its bending radius, pull strength etc. all have to comply with the regulation of corresponding product, when laying, answer SC, careful.When institute's laying optical cable needs to bear relatively large traction, carry out drawing (the yellow silk thread in cable outer sheath) by aramid fiber yarn, concrete grammar is as follows: first peelled off by the oversheath ring cutting of optical cable termination about 0.5m, then optical fiber is separated with aramid fiber yarn, fiber section excision is removed, with electrical adhesive tape, root parcel is wound up after aramid fiber yarn part is twisted, then aramid fiber yarn is fastened with pull rope.Drawn by aramid fiber yarn, can reach product nominal maximum tension, the loss caused in distraction procedure can be avoided, thus improve the laying quality of optical cable.

2, the maximum drawbar pull of cable.Cable is in distraction procedure, and pull strength should be less than cable and allows the 80% of tension force, when pull strength exceedes permission tension force, it is likely to result in irreversible damage, causing transmission performance to decline, when cable producer does not provide the ultimate value of cable pull strength, ordinary circumstance is as follows:
Single 4 core inside cables, maximum drawbar pull is 450N；
Single 6 core inside cables, maximum drawbar pull is 560N；
Single 12 core inside cables, maximum drawbar pull is 675N；
Single 4 pairs of UTP cables, maximum drawbar pull is 100N；
N root 4 is to UTP cable, and maximum drawbar pull is n × 50+50N.
Additionally, many 4 pairs of UTP cables, maximum drawbar pull not can exceed that 400N.
3, the minimum bending radius of cable.Cable is in laid processes, the bending radius of cable affects the quality of wiring equally, when cable bend radius is less than ultimate value, it may appear that the fibre core fracture of optical cable, the hidden danger such as the electric property reduction of cable, the ultimate value according to each cable bend radius of existing national regulation is as follows:
2 cores or 4 core optical cables, bending radius is more than 25mm；
Other core number and backbone optical cables, minimum bending radius is 10 times of cable outer diameter；
4 pairs of UTP cables, minimum bending radius is 4 times of the outside diameter of cable；
4 pairs of FTP cables, minimum bending radius is 8 times of the outside diameter of cable；
Big logarithm main cable, minimum bending radius is 10 times of the outside diameter of cable.
Additionally, when cable uses crane span structure to lay, in it, the bending radius of this cable is more than 300mm.
4, cable is reserved.Cable laid after in working area, telecommunication closet and equipment room leave surplus, to adapt to terminating, to detect and change.When requiring without design, ordinary circumstance is as follows:
Cable is reserved as 0.05m in working area；
Cable is reserved as 2m at telecommunication closet；
Cable is reserved as 3.5m at equipment room；
Reel stays, and length in reserve is 4.5m.
Additionally, cable also should do at crane span structure turning, the place of registering one's residence, building deformation joint etc. suitable reserved.
5, cable tie up fixing.Cable is distinguished the type of line, purposes etc. crane span structure planted agent and is carried out tying up fixing.Tie up fixing requirement as follows:
Every 2m～3m of cable horizontal segment carries out one-step bundling to be fixed；
Every 1m～1.5m of cable vertical section carries out one-step bundling to be fixed；
Cable turnover crane span structure position, turning carry out tying up fixing.
