Do you know the characteristics and advantages of flame retardant cables?
With the accelerating economic development in recent years, the number of large commercial buildings, industrial facilities and residential buildings has increased, and the use and density of wires and cables have also gradually increased. People have begun to pay more attention to fire safety and vigorously promote the use of various flame-retardant cables. Today, Foshan Yuejiaxin Wire and Cable Co., Ltd. will review the characteristics and advantages of flame-retardant cables for you.
Flame-retardant cables literally prevent the spread and burning of fire, prolong the time for the flame to spread along the cable, so that the flame will not burn more and more. Whether it is a single cable or a bundle of cables, when it burns, the spread of the flame can be controlled within a certain range to avoid causing greater losses, which fundamentally enhances the fire prevention effect of the cable line.
Flame-retardant cables and ordinary cables are basically the same in structure. The only difference is that flame-retardant materials are used in part or all of the insulation layer, inner and outer sheath layers, and tape fillers. The most intuitive difference is that flame-retardant cables have passed flame-retardant tests or certifications, which ordinary cables do not have.
The main performance characteristics of flame-retardant cables are that they will not expand the range after encountering a fire source, and they can extinguish themselves once they leave the open flame, but it does not mean that they will not burn.
Flame-retardant cables are divided into three grades: ZA, ZB, and ZC. Among them, ZA has the best flame retardant effect and is usually suitable for environments with high flame retardant requirements. In this case, Class A flame-retardant cables can be customized according to the user's own requirements. However, under normal circumstances, common ZB and ZC grade flame retardant cables can meet basic daily flame retardant use.
The above is an introduction to the characteristics and advantages of flame-retardant cables. I hope you can gain something from reading this. Here is a warm reminder: when purchasing cables and cable products, you must identify regular manufacturers and carefully check the appearance quality. Don't choose unqualified cables and cable products just because you want to be cheap.
