Non-combustible mineral insulated cables may be used in oil tankareas, public buildings with important wooden structures, hightemperature places, and other situations where fire resistancere are high and installation is acceptable and economicperformance is acceptable. When the self-capacity oil filled cableis applied to the public corridor, passenger tunnel, bridge andother situations re fire prevention treatment, it can beburied in sand. Close to the cable trench of high voltage current,voltage transformer and other oil-bearing e, it isadvisable to seal the trench cover plate in this section.
