Yes, mineral fire-resistant cables are truly fire-resistant cables that can maintain line integrity and power supply for at least 180 minutes in flames ranging from 950 ℃ to 1000 ℃. The principle of fire prevention lies in:

Inorganic materials: The insulation layer and sheath of the conductor are made of inorganic materials such as magnesium oxide or mica tape, which do not burn and do not produce toxic smoke.

High melting point: The melting point of copper sheath and mineral insulation materials is much higher than the flame temperature, which can ensure that the cable structure does not collapse in a fire.
