1. Do you need to use flame-retardant wires for home use?
Need. Because the flame-retardant wires have flame-retardant properties, even if there is a fire, it can reduce the loss at home more than ordinary household wires. In addition, when buying flame-retardant wires, it is necessary to identify the wires marked with ZR, and it is forbidden to buy wires that do not meet the safety standards to avoid adverse consequences.
2. What's the difference between flame-retardant cable and fire-resistant cable?
1, principle difference
The principle between them is different. Usually, cables containing halogen components have flame retardant effect, and the principle of flame retardant cables is to reduce the temperature of wires by precipitating water, thus extinguishing the fire. Fire-resistant cable is mainly based on the high temperature resistance of mica material to ensure that the cable can continue to work normally in fire.
2, the difference between structure and material
The structure and materials between them are different. The structure of flame-retardant cable is mainly composed of insulation layer made of flame-retardant material, outer sheath and protective sleeve made of flame-retardant material, and filling material made of flame-retardant material. Fire-resistant cable mainly adds a layer of fire-resistant layer between the insulation layer and the conductor of the wire, thus forming a cable that can resist fire and has fire resistance. Because the fire-resistant cable has a fire-resistant layer, it can be wound on the conductor with multi-layer mica tape, which can increase the fire-resistant time and ensure the normal operation of the line even if the flame of polymer burns.
