Special cables are cables with special functions, mainly including flame-retardant cables (ZR), low-smoke halogen-free cables (WDZ), fire-resistant cables (NH), explosion-proof cables (FB), rodent-proof cables and termite-proof cables (FS), resistance cables Water cable (ZS) etc. Flame-retardant cable (ZR), low-smoke halogen-free cable (WDZ): mainly suitable for important power and control systems. When the line encounters a fire, the cable can only burn to a limited extent under the action of external flames, generate little smoke, and have very little harmful gases (halogens) in the smoke. When the external flame disappears, the cable can also extinguish itself, minimizing the damage to humans and property caused by the fire.
Therefore, this kind of cable is widely used in important places such as petrochemical, electric power, metallurgy, high-rise buildings and densely populated areas. Fire-resistant cable (NH): Mainly suitable for particularly important power and control systems. When a line encounters a fire, fire-resistant cables can withstand high temperatures of 750~800℃ for more than 90 minutes, ensuring normal power transmission and gaining sufficient time for fire extinguishing and disaster reduction.
New products are constantly derived for special occasions, such as fire-resistant cables, flame-retardant cables, low-smoke halogen-free/low-smoke low-halogen cables, termite-proof/rat-proof cables, oil-resistant/cold-resistant/temperature-resistant/wear-resistant cables Cables, irradiation cross-linked cables, etc.
