对建筑物内通信电缆阻燃特性认识误区的剖析

摘要

梳理国内市场对“阻燃”概念的认识，对建筑物内通信电缆阻燃特性的认识误区进行剖析，提出需根据电缆的阻燃分级来辨识电缆的阻燃能力，以选择符合建筑物所要求的阻燃级别的通信电缆。%Reorganize the understanding of "flame retardancy" in domestic market, analyse the misunderstanding of flame retardancy of communication cable for buildings, propose the flame retardancy ability of cable should be indentified by classification of cable flame retardancy, so as to choose the appropriate communication cable classification which meets the requirement of buildings.
