通信光缆电缆的火焰蔓延标准研究

Study on flame propagation standard of electrical and optical communication cables

随着宽带接入技术的发展,特别是光纤到户(FTTH)技术的迅猛发展,在天花板、地板、地毯下、墙面线槽、楼房竖井等空间已开始敷设大量的通信光缆电缆,室内布线的通信光缆电缆的阻燃特性日益受到重视。文章主要介绍最新版本的GB/T18380系列标准中对火焰蔓延试验的相关规定,以帮助相关人员了解和掌握光缆电缆阻燃性能的检验方法和质量控制。

With the development of broadband access technology, especially of FTTH technology, daily increasing importance is attached to the flame retarding characteristics of the electrical and optical communication cables, which are laid in or under such places as ceiling, metope, building silo, floor and carpet, This article introduces the relevant specifications concerning the flame spread tests included in the latest version of Standard GB/T18380 to help the related technicians understand and master the test methods and quality control of electrical and optical cables.
