IClear concepts and advantages and disadvantages of flame-retardant cables, halogen-free cables and fire-resistant cables
1. The flame retardant cable is characterized by delaying the flame along the cable so that the fire will not expand. Because of its low cost, it is a variety of cables widely used in fireproof cables. Whether it is a single cable or laid in bundles, when the cable is burned, the flame delay can be controlled within a certain range, so it can avoid major disasters caused by fire and delay, thereby improving the fire protection level of the cable line.
2. The characteristics of halogen-free low-smoke flame-retardant cables are that they not only have good flame-retardant properties, but also that the low-smoke halogen-free cable materials are halogen-free, have low corrosiveness and toxicity during combustion, and produce a very small amount of smoke, thus It reduces the damage to people, instruments and equipment, and is conducive to timely rescue in the event of a fire. Although it has good flame retardancy, corrosion resistance, and very little smoke concentration, its mechanical and electrical properties are slightly worse than ordinary cables.
3. The fire-resistant cable can maintain normal operation for a certain period of time under the condition of flame burning, and can maintain the integrity of the line. When the fire-resistant cable is burned, the amount of acid e gas smoke is less, and the fire-resistant and flame-retardant performance is greatly improved, especially when it is burned, accompanied by water spray and mechanical blow, the cable can still maintain the complete operation of the line.
