The high flame retardant property of wire and cable protects safety at critical moments, which is mainly reflected in the following aspects:1. Fire preventionDelaying the spread of fire: Highly flame retardant wire and cable is not easy to burn when encountering a fire source, which can effectively delay the spread of fire. This feature can buy precious time for fire fighting and personnel evacuation in the early stage of the fire.Reducing the release of toxic gases: Highly flame retardant materials release less toxic gases when burning, reducing the harm of fire to the human body. For example, the use of flame retardant polyolefin materials can reduce the generation of toxic smoke and corrosive gases.2. Structural designInternal flame retardant layer: Adding a flame retardant layer to the structure of the wire and cable, such as an insulating layer filled with inorganic flame retardants, can form a heat insulation barrier under the action of an external fire source to prevent the flame from directly contacting the internal conductor.External sheath material: Using a sheath material with high flame retardant properties, such as flame retardant polyvinyl chloride (PVC) or flame retardant polyolefin, can improve the overall flame retardant properties of the wire and cable.3. Material selectionFlame retardant polymer: Use polymer materials with high flame retardant properties, such as flame retardant polyamide, flame retardant polycarbonate, etc., which can maintain certain mechanical strength and electrical properties at high temperatures.Inorganic flame retardants: Add inorganic flame retardants (such as aluminum hydroxide and magnesium hydroxide) to the materials. These flame retardants can release moisture, absorb heat and dilute combustible gases when heated, thereby improving the flame retardant properties of the materials.4. Production processExtrusion process: During the extrusion production process of wire and cable, control the temperature and speed to ensure that the flame retardant material is evenly distributed in the insulation layer and sheath to improve the overall flame retardant properties.Composite material technology: Through composite material technology, high flame retardant materials are combined with other functional materials (such as conductive materials and reinforcing materials) to produce wire and cable with better performance.Through the above measures, high flame retardant wire and cable can effectively improve safety at critical moments, provide protection for fire prevention, delay the spread of fire, reduce the release of toxic gases, and thus escort people's safety.
