Although mineral insulated cable and flame retardant cable both have the practical effect of fire safety, they are not the same kind of cable, and their structures are different, so are the temperature and time length when they are fire safe. In addition, there are some differences between mineral insulated cables and flame retardant cables.

Characteristics of mineral insulated cable:

Mineral insulated cable is a unique production process, which is composed of copper conductor, magnesium oxide insulating layer material and copper or alloy copper sheath, and has the characteristics of flame retardancy, smoke control, non-toxicity and fire prevention. The outer sheath can be made of organic materials. Considering the regulations of mineral insulated cable on resistance, wdz and flame retardancy, its characteristics meet the relevant requirements of national industry standard GB/T13033.

Flame retardant cable characteristics:

The function of flame-retardant cable is that it can still maintain all normal operations in a certain period of time when it is ignited by fire (with the ability to maintain detailed routes); There is also a low-smoke halogen-free flame retardant cable (WDZN), which has no halogen bulbs as raw materials, low combustion corrosion, less smoke when ignited, high transparency and good detailed characteristics of maintaining routes. It is a common indoor decoration cable for gathering places and high-rise residential buildings.  

Key differences:

When the highest temperature of mineral insulated cable reaches 950℃, keep everything connected to the power supply normally for 3 hours; When the maximum temperature of the flame retardant cable reaches 750℃, keep everything connected to the power supply normally for 90 minutes.
