摘要: 针对我国现有的电缆耐火试验方法不能满足相关规范对电缆的耐火性能的要求,借鉴国外试验方法,研究出新的耐火试验方法,即在同一根电缆试样上施加火焰燃烧、冲击振动和喷水试验。按该方法对市场上常见的6种不同结构耐火电缆进行验证试验,结果表明,电缆耐火性能的优劣主要取决于耐火层材料质量、电缆结构和电缆制造工艺水平。

Abstract: Against the problem that existing fire resistance test methods of cables in China cannot meet the requirements of the related codes for the fire resistance of cables, based on foreign advanced test methods, a new fire resistance test method was developed, that is, flame combustion, shock vibration and water spray test are applied on the same cable sample. The results show that: The technical content of this method is scientific and reasonable; The fireproof performance of cable mainly depends on the quality of refractory layer material, cable structure and cable manufacturing technology level.
