Fire Resistant Cable Vs Flame Retardant

Fire-resistant wires are a general term for wire and cable with fire performance, usually divided into the flame retardant wire and cable and fire-resistant wire and cable. It is easy for the general public to confuse flame retardant cables and IEC 60331 fire resistant cable.

However, flame retardant cables have many advantages that are more applicable to chemical companies, such as low halogen, low smoke flame retardant, etc. In general, fire rate power cables can replace flame retardant cables, while flame retardant cables cannot replace fire resistant cables. The following is a brief introduction to their differences and features by HOOHA.

Fire-resistant cable and flame retardant cable are not the same. The Halogen-containing cable flame retardant principle is to rely on the flame retardant effect of halogen. Halogen-free cable flame retardant principle is to rely on the precipitation of water to reduce the temperature to extinguish the fire roast. A Fire-resistant cable is to rely on the refractory layer of mica materials in the fire-resistant, heat-resistant properties to ensure that the cable works properly in the event of a fire.

As a new technology, the principle of the criticized cable, which is representative of fire-resistant cables, is that the cable can form a self-supporting ceramic body in the flame, which has a certain strength and can be used in the flame at a temperature of 650 to 1000°C and the cable will not be damaged. Therefore, the fire-resistant cable produces little smoke in the fire, and there is no halogen which is of great help to the environment. And the cable is easy to install, so many customers are willing to buy it.

Fire-resistant cables and flame-retardant cables are different in structure and materials.

The basic structure of the flame retardant cable is:

• The insulation layer uses flame retardant.
• The inner sheath and outer sheath are made of flame retardant.
• The tape and filling use of flame retardant material.

Flame-retardant wires are characterized by delaying the spread of flame along the cable so that the fire does not expand. Because of its lower cost, it is fire-resistant cable sales very good.

Fire-resistant cables can maintain normal operation for a certain period under flame burning conditions and maintain the line’s integrity. The amount of smoke produced when burning fire-resistant cable is less, especially with refractory materials, making fire-resistant flame retardant performance, especially in the case of burning, accompanied by water sprinkling and fire fighting, the cable can still maintain the integrity of the wire operation.
