1. Flame retardant: Under the specified test conditions, the sample is burned. After the fire source is removed, the flame spread on the sample is only within a limited range and extinguishes itself, that is, it has the characteristics of preventing or delaying the occurrence or spread of flame ability.
2. Fire resistance: the ability to continuously operate in a specified state when burning under a specified fire source and time, that is, the ability to maintain the integrity of the circuit. Flame-retardant and fire-resistant cables are a combination of the two.
It is easy to confuse the concepts of flame-retardant cables and fire-resistant cables. Although flame-retardant cables have many advantages that are more suitable for chemical companies, such as low halogen, low smoke and flame retardant, in general, fire-resistant cables can replace flame-retardant cables. Cables, and flame-retardant cables cannot replace fire-resistant cables.
In some important places, the use of wires and cables is clearly stipulated. For example, the communication room is very important and deeply affects our life and production. The flame-retardant and fire-resistant cables mentioned above are more commonly used.
