In extreme environments such as high temperatures and fires, mineral cables should be selected as fire-fighting cables.

I. Characteristics of Mineral Cables

Mineral cables are cables composed of inorganic substances, with both their conductors and insulation layers made up of minerals. Mineral cables have the following characteristics:

1. High-temperature resistance: As mineral cables are made of inorganic materials, they can operate in high-temperature environments without deforming or melting easily.

2. Fire resistance: When a fire occurs, mineral cables absorb heat and expand to form mineral oxides, creating a dense protective layer that effectively protects the equipment inside the cable.

3. Chemical resistance: Mineral cables have excellent chemical stability and can be used in chemically corrosive environments.

Ii. Application Scenarios of Mineral Cables

Mineral cables are suitable for the following occasions:

1. High-voltage areas: Mineral cables are suitable for high-voltage areas, such as high-voltage substations and power transmission and distribution.

2. High-temperature environment: In high-temperature environments, mineral cables can usually operate normally, which is one of their more prominent features.

3. Flammable areas: Mineral cables are suitable for flammable areas. Due to its excellent fire resistance, it can effectively protect the safety of equipment and personnel.

4. Chemical corrosion environment: Due to the excellent chemical corrosion resistance of mineral cables, they are suitable for places with chemically corrosive gases such as chemical plants.
