In the power cables, the flame retardant cable could be the most common used cable in our industrial and other application fields. Today this article aims to take with you to see the fire retardant cable more closely and if you are planning the procurement for your project, this article also will help you a lot.

Introduce

Flame retardant cable refers to a cable whose sample is burned under specified test conditions, and after the test fire source is removed, the flame spreads only within a limited range, and the residual flame or residual burn can be extinguished by itself within a limited time. The fundamental feature is: it may be burned out in a fire and cannot be operated, but it can prevent the spread of the fire. In layman's terms, if a wire catches a fire, it can limit the combustion to a local area without spreading, and protect other equipment and avoid greater losses.

The model of flame retardant cable

Flame retardant cable has copper core and aluminum core conductor, that consist of the whole flame retardant cable family. Below i list a chart where you can see whole flame retardant models could be seen in the market easily.

How is the flame retardant cable measured and tested?

There are 2 kinds of standards to identify the flme retardant cable in the world, they are the IEC and UL.

IEC flame retardant grade

In order to assess the flame-retardant performance of cables, the International Electrotechnical Commission has formulated three standards: IEC60332-1, IEC60332-2 and IEC60332-3. IEC60332-1 and IEC60332-2 are used to evaluate the flame retardant ability of a single cable when laid in an inclined and vertical position, respectively. IEC60332-3 is used to evaluate the flame retardant ability of bundled cables when burning vertically. In contrast, the requirements for flame retardant ability of bundled cables when burning vertically are much higher.

UL Flame Retardant Standard Any cable listed by UL that has been tested to meet a certain fire rating may be marked with the UL identification, fire rating and approval number. 

Distinguish the flame retardant cable and fire resistant cable

It is easy for ordinary people to confuse the concept of flame retardant cables and fire-resistant cables. Although flame retardant cables have many advantages that are more suitable for chemical companies, such as low halogen, low-smoke and flame-retardant, in general, fire-resistant cables can replace flame-retardant cables. , And flame retardant cables cannot replace fire-resistant cables. The main differences between them are:

The fire resistant cable has the mica materials inside which is very useful to resist the fire and flame, and the flame retardant has no those materials, so the fire resistant is better than flame retardant cable in some way, but it also decides on the specific application field, cause usually the fire resistant cable is more expensive than flame retardant cable, if your project has no such strict require, choose the flame retardant cable is enough. Apart from the mica materials, the differences between them is very little, in many cases, they are can be exchanged to be used each other.
