The processing method of the halogen-free low-smoke flame-retardant B1-grade cable comprises the following steps of: sequentially coating an inner ceramicized fiber belt layer, an oxygen barrier layer, an outer ceramicized fiber belt layer and a sheath layer from inside to outside through multi-layer wrapping, and filling a ceramicized fiber cotton filling layer in a combined gap of the cable core coated by the inner ceramicized fiber belt layer. The utility model forms multilayer protection for the insulated conductor of the cable core through the structural arrangement, so as to prevent the flame from burning to the inside of the cable core, and simultaneously prevent the external heat from being conducted to the insulated conductor of the cable core, and has the characteristics of good fire prevention and insulation performance and excellent halogen-free low-smoke flame retardant effect.What are the classification and model of flame retardant cable
Specifications and models of Class B1 cables: WDZB1-YJY, WDZB1-YJY23, WDZB1 N-YJY, WDZB1 N-YJY23, WDZB1 N-KYJYP23, WDZB1-KYJYP, etc.B1 flame-retardant cable for which occasions
GB 51348-2019 Electrical Design Standards for Civil Buildings When direct wiring is used in indoor places, the following provisions shall be met:
1, should be used not less than B2 grade flame retardant sheath insulated wire, its cross-sectional area should not be greater than 6mm;
2, fire-resistant cables and mineral insulated cable wiring fire-resistant cables and mineral insulated cables should have no less than B1 class flame retardant performance;
The selection and laying of fire power distribution lines shall meet the requirements for continuous operation time of fire protection electrical equipment (750℃,90min) and comply with the following provisions:
1. For the alarm bus of the automatic fire alarm system in the evacuation channel of densely populated places, the combustion performance B1 cable should be selected;
2. The alarm bus in other places should select cables with combustion performance not lower than Class B2;
3, fire linkage bus and linkage control line should choose fire-resistant copper core cable; combustion performance should comply with the provisions of GB 31247;
B1 cable must be used in super high-rise buildings and Class I high-rise buildings in civil buildings. At the same time, high-rise buildings, shopping malls, schools, subway stations, airports, stadiums, exhibition halls, hospitals and other densely populated public places will be widely used B1 cable.
