What are the characteristics of mineral-insulated cables? (Part 1)
Hongsheng: Because mineral-insulated cables are entirely composed of inorganic materials (metallic copper and magnesium oxide powder), they themselves cannot cause fires, cannot burn, or support combustion. Copper has a melting point of 1083℃, and the mineral insulation layer also has a melting point above 1000℃.

What are the characteristics of mineral-insulated cables? (Part 2)
Hongsheng: Because the actual normal operating temperature of mineral insulated cables can reach 250℃, IEC60702 stipulates that the continuous operating temperature of mineral insulated cables is 105℃. This is to consider the needs of terminal sealing materials and safety. Even so, its current carrying capacity far exceeds that of other cables, because mineral insulation has a better thermal conductivity than plastic, so at the same working temperature, the current carrying capacity is greater.
