[0002] Transformers, high-voltage shunt reactors and other oil-containing equipment are core equipment in power engineering. There are usually a large number of cables around such equipment. These cables are laid in cable trenches. According to the needs of cable operation and maintenance, the cable trenches need to use openable covers. Prefabricated reinforced concrete covers are generally used in engineering construction. There are inevitably gaps between adjacent covers and between the covers and trench walls. When oil-containing equipment explodes and spills oil due to moisture or other reasons, the high-temperature oil will flow into the cable trench along the gaps, causing the cables to catch fire and causing the fire accident to expand.
