Engineering Labels for Power Cables

Engineering Labels for Power Cables

This section describes the engineering labels for power cables, including DC and AC power cables.

Engineering Labels for DC Power Cables

DC power cable labels are affixed to the DC power cables that provide power supply for cabinets, including the -48 V, PGND, and BGND cables. Here, the DC power cables also include power cables and protection ground cables.

The labels for DC power cables are affixed to one side of the identification plates on cable ties. Table 4-28 describes the meaning of contents on the DC power cable labels.
Table 4-28  DC power cable label content

Content

Meaning

MN(BC)-B--48Vn

MN(BC): BC is written under MN.

B: chassis number, numbered bottom to top with two digits, such as 01.

N: power socket number, numbered 1 to 3 bottom to top and left to right.

On the loaded cabinet side, only MN is used to identify the cabinet.

On the power cabinet side, MN identifies the row and column number of the power distribution equipment like a control cabinet and distribution box, and BC identifies the row and column number of the -48 V connector. If there is no row or column number, or the connector can be identified without them, you can omit BC. It is unnecessary for BGND and PGND to identify the row and column number.

MN(BC)-B-BGND

MN(BC)-B-PGND

The label only contains information about the destination direction of the power cable. Information about the local end is unnecessary. That is, the label only contains information about the location of the equipment on the other end of the cable, the control cabinet, or the distribution box. Table D-8 lists the information that appears on the label about the two -48 V power supplies. Provide the information about other DC voltages, such as 24 V and 60 V in similar way.

Make sure that labels are affixed in the correct direction. That is, after the cable ties are used to bundle up the cable, the identification plates with labels should face up and the text on the labels in the same cabinet should be in the same direction. For details, see Figure 4-58.
Figure 4-58  Example of the labels for DC power cables

The labels in Figure 4-58 are described as follows:
  • On the loaded cabinet side, the label "A01/B08--48V2" on the cable indicates that the cable is -48 V DC supply, which is from the eighth connector in row B of -48 V busbar in the cabinet in row A, and in column 1 in the equipment room.
  • On the distribution box side, the label "B03--48V2" indicates that the cable is -48 V DC supply, connected to DC power socket 2 in row B, column 03 in the equipment room.
NOTE:

In the power distribution box or the first power cabinet of a row in a transmission equipment room, every terminal block on the -48 V connector bar is identified with a number. For example, in the above "A01/B08--48V2" label, "08" (or sometimes "8") is the numeric identifier of the terminal block.

PGND and BGND are both copper bars on which the terminal blocks are short-circuited. Therefore, you can connect to either terminal. It is only necessary to provide the row and column of the power distribution box, instead of the specific serial number of the terminal block on the copper bar. For example, if the label on the loaded cabinet side is "A01-BGND", it means that the power cable is a BGND that connects a BGND copper bar in the power distribution box in Row A, Column 01 in the machine room. Provide information on labels for PGND cables in a similar way.

Engineering Labels for AC Power Cables

AC power cable labels are affixed to both ends of an AC power cable that provides AC power supply to cabinets, including 220 V, PGND, and BGND cables. 220 V AC cables and related PGND and BGND cables are covered with an insulating sheath, so the labels need to contain only "AC" and the cabinet numbers.

Affix AC power cable labels to one side of the identification plates on cable ties. Table 4-29 describes the contents on AC power cable labels.
Table 4-29  AC power cable label content

Content

Description

MN-(B)-ACn

MN: serial number of the cabinet or the socket where the power is led in

B: chassis number, numbered bottom to top with two digits, such as 01.

n: power port number, numbered as 1 to 3 from bottom to top and left to right.

Serial number of the socket where the power is led in: the location of the socket is marked according to the actual situation. If the sockets can be identified by row numbers and column numbers, they can be numbered using the same rules as for the cabinets. If the sockets cannot be identified by rows and columns, specify the precise location to avoid confusion with other sockets.

The label only contains information about the location of the equipment on the opposite end of the cable as well as the power socket. Information about the local end is unnecessary.

Make sure that labels are affixed in the correct direction. That is, after the cable is bundled with cable ties, the identification plates with labels should face up and the text on the labels in the same cabinet should be in the same direction, as shown in Figure 4-59.

Figure 4-59  Labels for AC power cables

The labels in Figure 4-59 are described as follows:
  • On the loaded cabinet side, the label "A01-AC" indicates that the power cable is connected to the socket of Row A and Column 01 in the machine room.
  • On the power socket side, the label "B01-AC1" indicates that the power cable is connected to the AC power socket in Row B, Column 01 in the machine room.
