    Abstract: 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.
    Key words: cables; fire resistance; construction fibre fire; hydrocarbon fire; petrochemical plants fire
