Research on test methods for fire resistant
performance of dedicated fire cables

Abstract

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.

Key words: cables, fire resistance, flame application temperature, flame application time
