How are the advantages and disadvantages of flame retardant cables, halogen-free cables, and fire-resistant cables?

I. How are the advantages and disadvantages of flame retardant cables, halogen-free cables, fire-resistant cables?1. Flame retardant cables are characterized by delaying the flame along the cable ginger delay so that the fire does not expand. Because of its lower cost, it is a large number of fire-resistant cables used in the cable varieties. Whether it is a single cable or bundled laying conditions, the cable knows that when burning can control the flame ginger extension within a certain range, so you can avoid the major disasters caused by the fire delayed combustion, thus improving the level of fire protection cable lines. 2. halogen-free low smoke flame retardant cable is characterized not only by good flame retardant properties, and constitutes a low-smoke halogen-free cable materials do not contain halogens, corrosive and toxicity of combustion is lower, producing a very small amount of smoke. Produces a very small amount of smoke, thus reducing the damage to personal instruments and equipment, which is conducive to timely rescue in the event of fire. Although there are good flame retardant, corrosion resistance, very little smoke concentration. But its mechanical and electrical properties are slightly worse than ordinary cables.3. Fire-resistant cable is mainly in the flame burning condition can maintain a certain period of normal use, to ensure the integrity of the line. Fire-resistant flame retardant cable burning acid gas smoke is less, fire-resistant and flame retardant performance can be greatly improved. Especially in the burning time, accompanied by water spray and mechanical strikes, the cable can still maintain the integrity of the line to use.
