What are the advantages of mineral cables

Advantages of mineral cable:

1. Higher working temperature: The mineral cable can withstand continuous working temperature up to 250°C. And, in an emergency, the cable can continue to run at a temperature close to the melting point of the copper sleeve in a short time (the copper sleeve melts at 1083°C).

2. Long service life: The inorganic materials used in mineral insulated cables can ensure the stability and fire resistance of the cable, and ensure the service life of the cable.

3. Explosion-proof: The high-density insulating material in the mineral insulated cable can prevent steam, gas and flame from passing between the equipment parts connected to the cable.

4. Small outer diameter: the diameter of mineral insulated cables is smaller than other cables with the same rated current. If the mineral insulated cable is completely immersed in water through its seamless metal sheath, the mineral insulated cable can continue to run.

5. High mechanical strength: The mineral insulated cable is durable and can withstand severe mechanical damage without damaging its electrical performance.

6. Large current carrying capacity: For cables with the same cross section, mineral insulated cables can transmit higher currents than other types of cables. At the same time, mineral insulated cables can also withstand considerable overloads.

7. Short-circuit fault level: Under the same temperature, the short-circuit fault level of mineral insulated cables is significantly higher than that of other types of cables.

8. Grounding: For mineral cables, a separate grounding wire is not required, because the copper sheath used in the cable has already played the role of the grounding wire and can provide good low grounding resistance. As far as ESR wiring is concerned, in the MEN (multi-ground neutral) system, the external copper sleeve can be used as ground and neutral.

9. High corrosion resistance: The copper sheath of the mineral cable has high corrosion resistance. For most equipment, it does not require other protective measures. If the copper sheath of the cable is susceptible to chemical corrosion or serious industrial pollution, a plastic jacket should be used to protect the mineral insulated cable.
