Mineral Cables Have Advantages Over Traditional Cables

The durability and reliability of mineral cable are more advantageous than traditional cable. In addition, the mineral cable is also fire-resistant, mineral cable continuous working temperature of 250 ℃. It can supply power continuously for 3 hours at 950 °C-1000 °C, and can work close to the melting point of copper 1083 °C for short periods or extraordinary periods. Due to the excellent performance of the mineral insulated cable. Therefore, it is suitable for lines with a rated voltage below 1000V.

What Kind of Cable is the Mineral Cable? Do Not Be Confused With Other Cables.

A mineral insulated cable is a cable with a copper sheath wrapped around the copper conductor core and magnesium oxide powder as inorganic insulation material to isolate the conductor and sheath. The outermost layer can be selected as required with the appropriate protective jacket.

Fire-resistant in mineral insulated cable, due to the entire material of this cable, are used inorganic materials. So it has some advantages that are not possible with other cables. Fire resistance is applied in mineral insulated cables.
