What does the color of cable labels mean?

The color of cable labels has a specific meaning, mainly used to distinguish the type and purpose of cables, as well as to indicate their specific functions and performance. Here are some common meanings of cable label colors:

Yellow:

Used to identify high voltage, medium voltage, and low voltage power cables.

The yellow label indicates that it is a power cable and has a certain warning effect.

red

Used to identify fire-resistant cables or primary circuits.

The red label indicates that the cable is a fire-resistant cable that does not ignite in the event of fire and has good fire resistance, or that the circuit is an important primary circuit.

Blue:

Used to identify communication cables or other dedicated lines.

The blue label indicates that the cable is used for transmitting data and information, such as telephone lines, network cables, etc., or that the dedicated line has a specific purpose.

Green:

Used to identify control cables or secondary circuits.

The green label indicates that the cable is used for transmitting control signals, such as pneumatic control, hydraulic control, etc., or that the circuit is a secondary circuit of secondary importance.

Orange:

Used to identify high-temperature cables.

The orange label indicates that the cable can operate normally at higher temperatures, such as fire-resistant cables.

grey

Used to identify comprehensive cabling cables.

The gray label indicates that the cable is used in integrated cabling systems such as computer networks.

Black:

Used to identify the internal wiring of video cables or devices and equipment.

The black label indicates that the cable is used for transmitting video signals, such as surveillance systems, or for internal wiring.

White:

In some cases, white labels are used to identify tertiary circuits.

White may also be used for cable identification for other specific purposes.

In addition, the color of cable labels may also be influenced by specific industry standards or specifications, so in practical applications, relevant standards and specifications should be followed for selection and use.

Correctly using the color of cable label paper can help improve the recognition and safety of cables, facilitate users to quickly and accurately find the required cables in complex cable environments, and understand the type and purpose of cables, thereby avoiding the occurrence of incorrect operations or wiring errors.
