The classification of product use sites and the use of low smoke (low) halogen use sites shall be classified into special grade, grade 1, grade 2, and grade 3 according to the nature of the use of the building, fire hazard, evacuation, and difficulty of extinguishing, in accordance with Table 3— 2 regulations.
When low-smoke (low) halogen wire and cable are bundled and laid, fire-retardant wire and cable shall be used. The flame-retardant level shall be in accordance with Table 3-3 and Table 3-4. Under the action of external fire, the integrity and maintenance of the line shall be maintained. Where power is available, fire resistant wires and cables should be used.

Technical performance Wire and cable conductor Maximum temperature during normal operation and maximum temperature at short circuit (maximum duration not exceeding 5s);
Low-smoke low-halogen PVC insulation 70 °C, the maximum temperature does not exceed 160 °C in short circuit;
The cross-linked polyethylene insulation is 90°C, the thermoplastic low-smoke halogen-free polyolefin insulation is 80°C, and the maximum temperature during short-circuiting does not exceed 250°C. The radiation-crosslinked polyethylene insulation is 105°C.
The installation conditions and allowable continuous ampacity of the low-smoke no (low) halogen cable are the same as those of the corresponding non-low smoke no (low) halogen model cable and cable.
The cables and wires have low smoke, no (low) halogen, fire retardant and fire resistance when they are burned.
