Mineral fire-resistant cables are all composed of inorganic substances (metal copper and magnesium oxide powder), and mineral fire-resistant cables themselves cannot burn or aid in combustion without causing a fire. The melting point of copper is 1083 ℃, and the melting point of magnesium oxide is 2800 ℃. Therefore, this cable is truly a fireproof cable and can continue to supply power even in the event of a fire near the melting point of copper.

   　Mineral fire-resistant cables, also known as "flexible fire-resistant cables", have a variety of product models and specifications, but have the characteristics of softness, stability, and easy installation. They are environmentally friendly cables advocated by modern society. Therefore, mineral fire-resistant cables have developed rapidly in China.

　   Advantages and characteristics of mineral fire-resistant cables
      1. Fire resistance: The cable has two materials: copper and magnesium oxide, both of which are inorganic substances. Therefore, it should not burn or burn. The copper sheath melts at 1083 ℃, while the magnesium oxide insulation material solidifies at 2800 ℃. It does not burn at all and will not produce toxic smoke and gases when grilled by flames
      2. High working temperature: can withstand continuous working temperatures up to 250. However, in emergency situations, it is possible to continue working for a short period of time at temperatures close to the melting point of the copper sleeve.
      3. Long service life: Inorganic materials ensure the stability, lifespan, and fire resistance of the cable.
      4. Explosion proof: Highly rigid insulation material can prevent the passage of steam, gas, and flame between the equipment components connected to the cable.
      5. Small outer diameter: The diameter is smaller than other cables with the same rated current.
      6. Waterproof: It can be completely immersed in water and continue to operate mineral insulated cables with a smooth metal cover.
      7. High mechanical strength: sturdy and durable, able to withstand severe mechanical damage without damaging conductivity.
      8. Short circuit fault rating: At the same temperature, the short circuit fault rating is much higher than other types of cables.
      9. Grounding: There is no need for a separate grounding wire, as the copper cover used in fireproof cables has already served as the grounding wire, providing good low grounding resistance.
      10. High corrosion resistance: Copper covers have high corrosion resistance and do not require additional protective measures for most equipment. However, the copper sheath of fire-resistant cables is prone to chemical corrosion, so in areas severely polluted by industry, plastic sheath should be wrapped to protect mineral insulated cables.
      11. Good anti-corrosion and explosion-proof performance. Due to the use of seamless copper pipes as sheaths, they have waterproof, moisture-proof, oil and some chemical substances that can damage them. Copper pipes have considerable mechanical strength and therefore have good explosion-proof performance.
