I. What are flame-retardant cables and fire-resistant cables

Flame-retardant cables. Flame-retardant cables refer to those that can effectively prevent the spread of fire under experimental conditions. It is particularly suitable for use in families, shopping malls and factories. In case of fire, it may be burned down but not function properly. It can effectively prevent the spread of fire. Once a fire breaks out, this type of wire will confine the burning within an effective range and prevent the fire from spreading. It can protect the property or production equipment at home and prevent greater losses.

2. Fire-resistant cables. Fire-resistant cables, literally speaking, refer to those that can play a certain role in high-temperature environments. If a fire breaks out and the flames burn, maintaining operation for a certain period is more suitable for high-rise buildings, including underground streets and important mining enterprises. This fire-resistant cable can be used.

Ii. The Differences between Flame-retardant Cables and Fire-resistant Cables

The first difference lies in the structural materials. The materials used in flame-retardant cables are mainly flame-retardant raw materials, and their outer layer is made of flame-retardant sheaths, including their fillers. Fire-resistant cables are composed of conductors and insulating layers, with a fire-resistant layer added in the middle.

The second difference lies in the different principles. Flame-retardant cables are mainly produced through the flame-retardant effect of halogen materials. They can lower the temperature through the water outlet to extinguish the flame. Fire-resistant cables are made of mica materials. According to their properties, they have the characteristics of fire resistance and heat resistance. Therefore, in the event of a fire, they can extend their service life.
