The different colors of cable fire jackets are often used to distinguish between different functions or to comply with specific standards. Although there is no unified international standard that specifies the specific meaning of each color, in some regions or industries, common color codes may have the following common meanings:
Red: Usually indicates an emergency or warning. The red bushing may be used to identify major power lines, emergency power supplies, or other critical systems so that they can be more easily identified in the event of an emergency.
Blue: It may indicate a cooling system or a water source. Blue sleeves may be used to identify cooling-related pipes or systems for easier location during maintenance or emergency situations.
Yellow: Usually a warning or attention. Yellow sleeves may be used to identify potentially hazardous areas, precautions, or equipment that requires attention.
Green: Probably indicates safety or underground facilities. Green sleeves may be used to identify security systems, underpasses, or other safety-related equipment.
Gray or black: may be used for general purposes and has no specific meaning. These colored sleeves may be used for general cable protection or other purposes.
It should be noted that different regions, different industries or different standards may have different color coding regulations, so it is best to select and use the color of the cable fire jacket according to the local standards or specifications when using specific use.
