What are the advantages of mineral-insulated cables?
Hongsheng: Mineral Insulated Cable Because all materials of this cable are inorganic, it has some advantages that other cables do not have. 1. Fire resistance The two materials used in mineral insulated cables, copper and mineral insulation, are inorganic. This cable will not burn or support combustion, and can continue to operate under conditions close to flames. Copper melts at 1083℃.

Because all the materials of this cable are inorganic, it has some advantages that other cables do not have.
1. Fire resistance
Mineral Cable Copper and the two materials used in mineral insulation are inorganic. This cable will not burn or support combustion and can continue to operate in close proximity to flames. Copper melts at 1083℃.
2. High operating temperature
Mineral insulated cables can withstand continuous operating temperatures up to 250℃. In addition, in emergencies, the cable can continue to operate for a short time at temperatures approaching the melting point of the copper sheath.
3. Long service life
Mineral insulation Cable The inorganic materials used in can ensure the stability, long life and fire resistance of the cable.
4. Explosion-proof
The highly compacted insulation material in mineral insulated cables prevents steam, gases and flames from passing between the cable and connected equipment components.
5. Small outer diameter
Under the same rated current, mineral Cable has a smaller diameter than other cables.
6. Waterproof material
Hongsheng
7. High mechanical strength
Mineral insulation Cable Durable and can withstand severe mechanical damage without compromising its electrical performance.
8. Large current carrying capacity
For cables with the same cross-sectional area, mineral insulated cables transmit higher currents than other types of cables. At the same time, mineral insulated cables can also withstand considerable overloads.
9. Short-circuit fault level
At the same temperature, mineral insulation Cable has a significantly higher short-circuit fault rate than other types of cables.
10. Grounding
For mineral insulated cables, no separate grounding conductor is required because the copper sheath used in the cable acts as a grounding conductor, providing good low grounding resistance. In terms of grounding sheath return (ESR) wiring, in MEN (multiple grounded neutral) systems, the outer copper sheath can be used as both grounding and neutral conductors.
11. High corrosion resistance
Hongsheng: Cable The copper sheath has high corrosion resistance and does not require additional protection measures for most installations. When the cable's copper sheath is susceptible to chemical corrosion or severe industrial contamination, mineral insulated cables should be protected with a plastic outer sheath.
