电力电缆通道光缆防火应用研究

Research on the Application of Fire Protection of Optical Cable in Power Cable Channel

文章介绍了目前光缆在电缆沟中采用的阻燃套管、耐火槽盒两种防火措施,提出了一种采用新型耐火多功能光缆的防火措施,并对三种防火措施进行了特性对比及应用场景分析,最后针对光缆在电缆沟中接头区防火薄弱的问题提出了利用耐火砖砌防火井的光缆接头防火解决方案。

This paper introduces two kinds of fire-proof measures of fire-retardant sleeve and fire-resistant box used in cable trench at present,and puts forward a new fireresistant multi-functional cable,compares the characteristics of the above three fireproof schemes,and analyzes the application scenarios.Finally,it puts forward the fireproof solution of the joint of the optical cable in the joint area of the cable trench by using the fire-resistant brick to build the fire-proof well Resolution.
