Fire Resistant Cable Buying Guide

 

Fire resistant cable can mean the difference between disaster and control.

In many applications, especially safety-related, fire resistant cables are a necessity.

They can ensure circuit integrity even when there’s a fire.

The fire resistance property of a cable is highly dependent on its quality.

A low-quality, cheaply-made cable may only be fire resistant at the extent of the name.

Its performance with or without fire conditions is highly dependent on the right construction, quality materials, and standards that have been set by international bodies.

In this post, you’ll learn all the aspects of fire resistant cables that will ultimately help you find the right product for your particular application.

What are Fire Resistant Cables?

Fire resistant cables are basically made of a material that can resist fire for a period, ensuring the power supply is uninterrupted while the rescue efforts are underway.

These are also important in applications that are traditionally prone to coming in contact with fire, such as during fire rescue operations.

Essentially, these are like any other cables as the main purpose is supplying power.

However, the material and the constructions distinguish them from regular cables.

These cables can withstand temperatures in hundreds and sometimes even thousands of degrees (Fahrenheit).

Fire resistance is an umbrella term for cables that are fireproof to some extent.

Many different types of cables can fall under this category, each serving its unique purpose or application.

Difference between Fire Resistant and Fire Retardant Cables?

The terms fire resistant and fire retardant are often used interchangeably for cables.

However, these are not the same thing. Knowing the difference is crucial because, for certain applications, only fire resistant cables may work.

Fire retardant cables are made of materials that do not convey or propagate a fire. In simpler words, the cables are designed not to start a fire themselves.

Fire resistant cables are designed to withstand fire and function normally for a period of time.

In essence, a fire resistant cable will continue to work even in a fire condition, at least for a set period. However, the same cannot be said about fire retardant cables.

They may not start a fire but may be vulnerable to damage in case of a fire because of other causes.

Fire retardant cables are not used for applications where circuit integrity needs to be maintained even when a fire is raging.

In such applications, only a fire resistant cable can work and maintain power supply.

Although the underlying purpose behind using these cables is essentially the same, the way they behave in case of a fire differs.

You can say that a fire resistant cable is also a fire retardant cable, but a fire retardant cable is not necessarily a fire resistant cable.

Construction of Fire Resistant Cables

The construction of a fire resistant cable can vary depending on the type of cable.

Similarly, the materials may also vary. So there isn’t a standard blueprint of construction.

However, certain essential parts are universally present in all fire resistant cables.

The typical construction of a fire resistant cable includes:

Conductor

The conductor is the metallic core that basically carries the current.

This is most commonly copper as it has high conducting capabilities.

Now, the conductor comes in different shapes and sizes that depend on the cable type and, more importantly, the standard it follows.

Some examples include stranded, compacted, and sector-shaped.

The standard the cable meets will tell you what cable it is, as standards usually dictate the features of the conductor, which of course, are in line with the application they are intended for.

Fireproof Layer (Tape)

This is the component that makes the fire resistant cable what they are.

This fireproof layer protects the conductor, which is moving the current.

It’s most commonly mica tape that’s fire resistant.

It provides great insulation from the fire up to a thousand Celsius temperatures.

However, there is not a universal fireproof tape standard, so it may differ from cable to cable.

Some may be insulated enough to fire for half an hour, while some may have ample resistance to keep the circuitry intact for several hours.

Insulation

The insulation layer is pretty much like the insulation in any cable, except the materials used are in line with the fire resistance requirements of the cables.

For instance, it has become a standard that fire resistant cables don’t contain any halogens in insulation or otherwise for safety reasons.

Insulation also depends on the type of cable and application.

Some may need thicker insulation, while some may do with a thin layer.

However, the purpose is the same, which is ensuring the current doesn’t travel out of the conductor.

Each core needs its own insulation, so if the fire resistant cable has multiple cores, it should have each core properly insulated.

Screen or Assembly

In multi-core cables, the conducting cores are laid together and covered with a non-hygroscopic material, typically a polymer compatible with the insulation material.

It serves as both a barrier between the outer layers and the insulation, but it also helps give the cable a circular shape, which is what most cables have.

It binds the cores together, so they become one unit and don’t separate out.

Bedding

The bedding is like an inner sheath that, again, supplements protection and insulation.

It’s an extruded low-smoke halogen-free material (LSHF).

This is the flame retardant layer that ensures the cables don’t propagate fire.

Armor

After bedding, it’s the armor layer, which is optional and only present in so-called armored cables.

Armor is necessary for cables that may be underground because armoring can protect from mechanical pressure.

It basically further hardens the cable so it can withstand pressure and weight.

For single-core, it’s typically aluminum wire, and for multiple-cores, it’s typically galvanized steel wire.

Armor in cables doubles as Earth Continuity Conductor (ECC).

Outer Sheath

This is the outermost part of the cable that will likely come in contact with the fire.

It’s also made of LSHF materials.

The typical sheath color is black, but can also be red, blue, or orange.

It protects the cable from all the outer elements.

The standards dictate the sheath material and thickness, so materials may vary by standards the cable follows.

Characteristics

Apart from the construction, the characteristics of the cable are another important consideration.

In fact, they may be the deciding factor for you as they ultimately determine what application and quality standards they meet.

Voltage Rating

Like most cables, the first consideration is the voltage rating, i.e., how much voltage a cable can handle.

Fire resistant cables come in both low-voltage and high-voltage ratings as they are common in all kinds of applications that use a variety of voltage.

From as low as 300/500 V to 0.6/1 kV, you can easily find the voltage you’re looking for.

It’s important to note that certain constructional differences may be preset because of voltage rating.

For instance, you won’t find mineral insulation in low-voltage fire resistant cables.

That’s mainly because such cables are difficult to install and low-voltage cables may be used indoors and in equipment.

Operating Temperature

The operating temperature of fire resistant cables is even more so important than regular cables.

While almost all types of cables have high operating temperatures to withstand hot climates and high underground temperatures, fire resistant cables have to be able to withstand fire, so their operating temperatures are much higher than average cables.

Typically, fire resistant cables have operating temperatures of 650 to 950 degrees.

However, some cables may have even higher operating temperatures.

This basically means that they can withstand these high temperatures which can only be possible in case of a fire.

Cores

Fire resistant cables can be single-core or multiple cores.

For some applications, a single core cable might be enough. However, for heavy applications with higher voltage requirements, multiple core cables are suitable.

Flexibility

The flexibility of a cable can be important when it’s laid on uneven surfaces or may need to twist.

Nowadays, most cables are bendable, but some are highly flexible and better for such a difficult layout.

The bendability of the cable depends on the materials, especially the insulation, and the outer sheath.

Standards

Standards from international bodies help you choose the right cable.

Not only does it ensure that the cable has met the physical or technical requirements, but it also ensures that the cable has been tested.

There are many different cable standards globally. Some are more globalized than others, so you may want to look for the standards typically followed in the region you’re in.

These standards also define specific applications for the cables, so you can be sure that the cable is best for the purpose you’re using it for.

The following are the common standards for fire-resistant cables:

  • British Standard Institution (BS)
  • International Technochemial Commission (ICE)
  • European Norm (EN)
  • Deutsche Institut for Normung (DIS)
  • Comitato Elettrotecnico Italiano (CEI)
  • Norme Belge (NBN)
  • Singapore Standard (SS)
  • Norme Francaise (NF)

Category

In addition to the standards, you’ll also see categories within each standard.

These categories are denoted by alphabets, such as A, B, W, etc.

In fire resistant cables, categories tell the temperature resistance as well as how long the cable can maintain circuit integrity in that temperature.

While the standard tells the application and some technical details, the category defines these two crucial characteristics.

Some fire resistant cable categories also indicate that these cables are waterproof (category W).

Applications

Fire resistant cables are used in many industries, both big and small.

These play an important part in the electrical infrastructure of these industries, which goes to show how crucial their role is in the overall cable ecosystem.

Since these are made to withstand fire, the most application is in emergency services.

Fire resistant cables are used in emergency lighting and in rescue equipment, which may have to work in a fire.

These cables are also used in fire security systems in all sorts of buildings, particularly commercial and public structures.

Therefore, these are used in schools, offices, hotels, public libraries, factories, etc.

Another important, rather, a most common application of fire resistant cables is power supply.

It supplies power to critical infrastructure that may require an uninterrupted supply of electricity.

This could be security systems, servers, communication centers, and data warehouses.

Benefits

The main benefits of using fire resistant cables are:

  • Uninterrupted Power Supply: The obvious benefit is that these cables maintain the circuit integrity and keep supplying power for a considerable duration, under which the fire may be controlled. This ensures that critical systems and infrastructure always have power even when there is a fire.
  • Halogen-Free: These cables are halogen-free as these can come in contact with flames. Those flames can produce harmful emissions if there are any halogens in the construction of the cables.
  • Tough Construction: Such cables are inherently quite tough, so they can withstand rough environmental conditions such as very high and low climatic temperatures, mechanical pressure, abrasion, etc.
  • Emergency Operations: Fire resistant cables are used in rescue operations in case of fire. These cables power equipment and lighting that can help save lives in a dangerous situation.

Conclusion

Whenever you’re buying fire resistant cables, pay attention to the materials and the standards, including the category.

Since their function is so critical for sensitive systems, quality is uncompromisable.

With newer technologies, even higher temperature resistant cables are coming.

But its equally important how long they can withstand that temperature.

Also, don’t mix fire resistant with fire retardant as those are different things.
