Study of empirical analysis of cable and passive fire protection of cable fire.

This review demonstrates that electrical cable fires remain a significant threat to modern residential, commercial, industrial, and critical infrastructure because cables act as both ignition sources and combustible fuel. Fire behaviour is controlled by the interaction of conductor material, insulation properties, cable geometry, installation arrangement, electrical loading, and environmental conditions. Understanding these interactions is essential for improving fire risk assessment and ensuring the reliability of electrical systems. Empirical analysis of electrical cable and passive fire protection of cable fire. The literature confirms that copper conductors, metallic armouring, and suitable insulation materials can improve fire resistance, while passive fire protection systems such as intumescent coatings and fire barriers significantly reduce flame spread and delay cable failure. Nevertheless, current testing standards do not fully represent the complex conditions encountered during actual industrial fires, where multiple electrical and thermal hazards occur simultaneously. The review also identifies important knowledge gaps related to combined fault conditions, long-duration fire exposure, cable ageing, ventilation effects, and bundled cable installations. Addressing these gaps through full-scale experimental studies  will improve the prediction of cable fire behaviour and enhance the design of effective passive fire protection systems. Overall, integrating optimized cable design, appropriate passive fire protection, realistic fire testing, and predictive fire modelling will strengthen electrical fire safety, improve system resilience, and reduce the risk of fire-related damage and service interruption in critical infrastructure.
