Cable, distribution cable and optical cable and other wire intertwists are conducive to control the arrangement of cable, distribution cable and optical cable.
Specifically, for controlling cable, in the control cable connection point for measuring the first equipment to the of cable laying slot
The air line distance A of side wall opening1It later, can be to control one end of cable as starting point, apart from starting point B on control cable1Place
It makes marks and (crosses for example, by using marking pen), wherein B1=A1Then+200mm will control one end of the starting point of cable to pass through first
Sidewall opening, until mark and the first side wall register.Accordingly for distribution cable, length in reserve can be B2, B2=
A2+ 200mm, for optical cable, length in reserve can be B3, B3=A3+200mm。
Preferably, it is laid with before cable, control cable and distribution cable setting can also be identified in cable laying groove,
In the following manner specifically may be used：
Wire size pipe is arranged on control cable and distribution cable.
Cable is set to be listed respectively at the both ends at the both ends of control cable and distribution cable
Before control cable and distribution cable is laid with, need to measure cable, to be cut into the control of sufficient length
Cable and distribution cable processed.Simultaneously because control cable and distribution cable are usually constructed with more, every control cable and distribution are electric
Cable may be connect with the distinct interface in equipment, thus can by set mark to every control cable and distribution cable into
Row is distinguished.It can specifically be distinguished in a manner that wire size pipe is set and cable is listed.
For controlling cable, when setting wire size pipe, a wire size pipe can be arranged in the middle of control cable, then
A wire size pipe is arranged at interval of 20m to the both ends of control cable, until wire size pipe and the distance at control cable both ends are insufficient
20m.At control cable both ends, cable can be set to be listed respectively at the 2m of end face, cable, which is listed, can pass through nylon cable tie
It is fixed on control cable.
Optionally, wire size pipe is thermal shrinkage type.
It is contemplated that also needed to before control cable, optical cable and distribution cable is laid with to control cable, optical cable and
Distribution cable is checked, to ensure to control cable, optical cable and distribution cable that quality problems are not present.
S24：Cable is laid in cable laying groove.
