摘要
为了确保消防配电线路中所选用的耐火电缆,能够满足消防用电设备在火灾时持续运行时间的要求,对电缆耐火性能科学评价非常重要。综述了国内外主要的电缆耐火性能试验方法,分析了国内电缆耐火性能标准体系的不足,提出了科学合理的试验方法以评价电缆耐火性能的建议,旨在为国内耐火电线电缆产品的质量提升及规范化生产提供依据。
To ensure the fire resistance of cables that used in the fire-fighting power distribution wires are able to meet the requirements of the continuous operation of fire-fighting electrical equipment during a fire,it is of great importance to evaluate the fire-resistant performance of cables in a scientific way.In this paper,the main methods of testing the fire resistance of cables adopted by China and other countries are summarized,the shortcomings of China’s standard system to evaluate the fire-resistant performance of cables are analyzed,and some scientific and reasonable test methods of evaluating the fire resistance of cables are suggested to provide solid basis for the quality improvement and standardized production of fire-resistant wires and cables in China.
