Is the fire-resistant cable a flame-retardant cable?
October 29, 2022
Flame-retardant cables, halogen-free cables, fire-resistant cables, clear concepts and advantages and disadvantages
Flame retardant cable is characterized by retarding the spread of flame along the cable so that the fire will not expand. Because of its low cost, it is a large variety of cables used in fire protection cables. Whether it is a single cable or a bundled cable, the cable can control the spread of the flame within a certain range when it is burned. Therefore, it is possible to avoid the major disasters caused by the ignition of the fire, thereby increasing the fire protection level of the cable line.
Halogen-free and low-smoke flame-retardant cables are characterized by not only good flame-retardant properties, but also halogen-free materials that constitute low-smoke halogen-free cable materials, which are less corrosive and toxic when burned, and produce a very small amount of smoke, thereby reducing the Damage to people, equipment, and equipment is conducive to timely rescue in the event of fire. Although it has good flame retardancy, corrosion resistance, and low smoke concentration, it is slightly inferior in mechanical and electrical performance to ordinary cables.
Fire-resistant cables are normally operated for a certain period of time in the event of a flame, maintaining the integrity of the line. The flame-retardant cable produces less sour fume when burned, and the fire-retardant flame-retardant performance is greatly improved. Especially when burning, along with the water spray and the mechanical blow, the cable can still maintain the complete operation of the line.
