Caledonian Flame Retardant Cable

Flame Retardant cables are designed for use in fire situations where the spread of flames along a cable route needs to be retarded. Due to relative low cost, fire retardant cables are widely used as fire survival cables.
Flame retardant cables are not rated to continue to operate under fire circumstance but it will resist the propagation of fire into a new area by having behavior in fire under defined conditions which is proven by passing the test as per IEC 60332.
In the event of fire, the ordinary flame retardant cable may produce a large amount of corrosive gases and smoke after combustion, and can be used in general occasions with low flame retardant requirement.
Ordinary flame retardant cable’s flammability has A, B, C, D four categories:
For Class A and Class B fire tests, the fire time is 40 minutes, and for Class C and Class D fire tests, the fire time is 20 minutes, and the charring height does not exceed 2.5 m.
The outer sheath of Caledonian flame retardant cables is flame retardant PVC. These cables are slightly more expensive than normal PVC cables and are widely used in power stations, mass transit underground passenger systems, airports, petrochemical plants, hotels, hospitals, and high-rise buildings and etc.
Caledonian flame retardant cables consist of a wide range of power cables, control cables, instrumentation cables, coaxial cables, and Cat5 & 6 cables, all of which comply with the main international standards (IEC 60502-1,BS 6724,BS 5308,BS 7211, BS 5308 Part1 Type1 & 2,BS 5308 Part 1 Type 1,BS 5308 Part 1 Type 2 ,EN50173 ,EIA/TIA 485, MIL-C-17,Telcordia GR409-core/ TIA/EIA 568B.3 / ICEA-S-83-596,Telcordia GR-20 /RUS 7 CFR 1755.900 (REA PE-90) / ICEA S 87-640,and etc.).
