消防设备配电线缆的选用及敷设研究

本文先介绍了国内外设计规范对消防设备配电线缆的要求,再对各类线缆的燃烧特性进行了分析,着重就矿物绝缘电缆与其它有机耐火电缆的性能特征、经济价格进行了分析对比,提出不同建筑物的消防设备在火灾发生期间的最少连续供电时间可分不同等级,电线电缆也可按使用场所进行分级,以及线缆应采取正确的敷设方式。

Research on the selection and laying about electric wires or cables of fire fighting equipment

This article introduces the requirement about electric wires or cables of fire fighting equipment in country or abroad,and analyses on the combustion feature of all kinds of wires and cables.It lays emphasis on the analysis and comparison on the quality and specificity of mineral insulated cable and organic fire-resistance cable,then it proposes that the least continuous power supply time of fire-fighting equipment in different buildings during fire hazard should be graded,and proposes that electric wires and cables also should be graded by using place and should be taken by the right laying method.
