Publish Time: 2025-01-27
In modern electrical systems, PE cable material is widely used due to its excellent physical properties and processing properties. However, the flammability of PE cables has always been the focus of attention, especially when a fire occurs, the smoke and toxic gases produced by its combustion may intensify the fire and threaten the safety of personnel. Therefore, improving the flame retardant performance and fire safety of PE cables has become a hot topic in current research.The improvement of flame retardant performance is mainly achieved by adding flame retardants, blending modification, and using halogen-free flame retardant systems. For example, halogen flame retardants such as antimony trioxide combined with halogen compounds can significantly improve the flame retardant level of PE cables. In addition, compounds such as organic acids and ammonium phosphate are directly added to PE as flame retardants, which can also effectively improve its flame retardant properties. A more environmentally friendly option is to use halogen-free flame retardant systems, such as metal hydroxides and phosphorus-based flame retardants, which can absorb heat and release water vapor when burning, thereby inhibiting the spread of flames.In addition to the application of flame retardants, blending modification is also an effective way to improve the flame retardant performance of PE cables. By blending with rubber materials such as butyl rubber and natural rubber, the impact resistance and flame retardant properties of PE cables can be significantly improved. In addition, the use of composite material technology, such as compounding PE film with materials such as PET or aluminum film, can also indirectly improve the flame retardant properties of PE cables.In terms of fire safety innovation, many advanced technologies are incorporated into the design and production process of PE cables. For example, the use of intumescent flame retardants can form a stable carbon layer during combustion, reduce smoke generation, and significantly improve the limiting oxygen index of PE cables. At the same time, by optimizing the structural design of the cable, such as adding a flame retardant layer or using a multi-layer structure, the fire resistance and flame retardant properties of the cable can be further improved.In addition, with the development of intelligent technology, the fire warning and monitoring system of PE cables has also been innovated. By embedding sensors in the cable, the temperature, current and other parameters of the cable can be monitored in real time. Once an abnormal situation is found, the system will immediately issue an alarm, thereby effectively preventing the occurrence of fire.In summary, the improvement of the flame retardant performance of PE cable material and the innovation of fire safety are important topics in the current field of electrical system safety. By adopting advanced flame retardants, blending modification, composite material technology and intelligent monitoring methods, the flame retardant performance and fire safety of PE cables can be significantly improved, providing strong guarantees for the stable operation of electrical systems and personnel safety.
