The difference between flame-retardant cable,

1. The characteristic of flame-retardant cable is to delay the flame's spread along the rope so that the fire will not expand. Regardless of whether it is a single cable or a bundle laying, the line knows that the flame spread can be controlled within a specific range when burning. It can avoid major disasters caused by fire and prolonged combustion, thereby improving the cable line's fire protection level.

2. The characteristics of halogen-free low-smoke flame-retardant cables are that they have not only good flame-retardant properties but also the halogen-free materials constituting the low-smoke and halogen-free cables have low corrosiveness and toxicity during combustion and produce a minimal amount of smoke, thereby reducing Damage to persons, instruments, and equipment is conducive to the timely rescue in the event of a fire. However, it has good flame retardancy, corrosion resistance, and very little smoke concentration.

3. The fire-resistant cable can maintain regular operation for a certain period under the condition of flame burning and preserve the integrity of the line. Fire-resistant cables produce less acid gas and smoke when they burn. Their fire-resistant and flame-retardant properties are greatly improved, especially when roasted, accompanied by water spray and mechanical blows. The cable can still maintain the integrity of the line.

4. Some electrical designers are not clear about the concept of flame-retardant cable and fire-resistant cable and do not know the two's structure and characteristics. As a result, they cannot properly design and select these two cables according to the power supply requirements. Carrying out design agency or supervision work on-site Can not correctly guide the laying of these two cables.
