Description
技术领域 technical field

背景技术 Background technique
在冶金、电力、石化等对线缆具有移动、抗辐射等特殊要求的工作环境中，线缆敷设安装后，在使用中易受到外力的拉伸，同时缆芯易于受到导线和信号线之间以及环境电磁干扰的影响，从而不能保证电力和通讯的传递通畅，造成巨大的经济损失。其现有的电缆中采用含卤的聚乙烯阻燃材料，因而具有良好的阻燃特性，但是在电缆燃烧时会释放大量的浓烟和卤酸气体，卤酸气体对周围的电气设备有腐蚀性危害，救援人员需要带上防毒面具才能接近现场进行灭火，电缆燃烧时给周围电气设备以及救援人员造成危害。 In metallurgy, electric power, petrochemical and other working environments that have special requirements for cables such as movement and radiation resistance, after the cables are laid and installed, they are easily stretched by external forces during use, and the cable core is easily affected by the gap between the conductor and the signal line. As well as the influence of environmental electromagnetic interference, the smooth transmission of power and communication cannot be guaranteed, resulting in huge economic losses. Its existing cables use halogen-containing polyethylene flame-retardant materials, so they have good flame-retardant properties, but when the cables burn, they will release a large amount of dense smoke and halogen acid gas, which will corrode the surrounding electrical equipment. Rescue personnel need to wear gas masks to approach the scene to extinguish the fire. When the cable burns, it will cause harm to the surrounding electrical equipment and rescue personnel.
