Mineral insulated cables are entirely composed of inorganic substances (metal copper and magnesium oxide powder). The cable itself will not cause a fire; it is impossible for it to burn or support combustion. With a copper melting point of 1083 ºC and a mineral insulation layer melting point above 1000 ºC, this cable maintains power supply during extreme fire conditions, making it a true fireproof solution.
The normal use temperature of mineral insulated cables can reach 250 ºC. According to IEC60702 standards, the continuous working temperature is rated at 105 ºC for terminal sealing safety. Its current-carrying capacity significantly exceeds that of plastic cables due to the superior thermal conductivity of mineral insulation.
Mineral insulated cables are widely utilized in critical environments requiring high safety standards, including:
