Chapter 6 Cable Installation
Figure 6-3 Positions of Power Cable Labels
The flag-shaped power cable label is divided into two areas: L and R, whose meanings
are as follows:
a.
L: fill with the location code of the local equipment, indicating the location of the
equipment connected with the local end the power cable.
b.
R: Fill in the position code of the remote equipment, i.e. the position of the power
cable at the equipment of the other end. If the other end is connected to the power
distribution frame, the power distribution frame and the nature of the power cable
should be indicated Example: Distribution GND.
The contents of the two labels at the two ends of the same power cable should
be opposite. For example, the content filled in the L area of the label at one end
should be consistent with that in the R area of the other end.
6.1.1.2 Cabling Requirements for Internal Cables
1.
Routing Methods of Internal Cable
Cabling requirements of internal cables:
a.
Lay the internal cables according to the system cabling rules specified in related
documents. The cable should be laid neatly and attractively. All cables should be
bundled and laid in a consistent direction, with even interval between cable ties.
b.
Identify the two ends of the cable clearly with labels. Do not incorrectly insert them
or miss any cable.
c.
Lock the cable connectors tightly with the locking device.
d.
Separately bind the signal cables and the strong-current cables to avoid
interference to the signals.
e.
The bending should be smooth and round. The minimum bending radius is no
less than 100 times of the cable outer diameter.
f.
Bind the surplus length of the cables inside the cabinet on the side cabling beam
of the cabinet after arranging them neatly and in order to avoid damages to the
cables due to shaking during the transportation.
