Flame retardant cable, fire resistant cable:The difference

At the outset of infrastructure development, the issue of safety hazards became a top priority. Recognizing the paramount importance of preventing fires from crippling essential services, the term “Fire Resistant Cables” was coined, serving as a baseline safety measure.

Why are fire resistant wires the first choice in modern buildings? The use of cables assures that vital systems continue to function even in the harshest conditions, potentially saving lives and minimizing damage. So follow our blog to explore fire resistant power cables in further detail.

What is Fire Resistant Cable?

Understanding the nature of fire resistant cable starts with recognizing its purpose. Fire rated cables are designed to maintain circuit integrity and continue to function during a fire. This is achieved through the use of special fire resistant cable materials, such as the commonly used XLPE, MICC, and notably materials used in the fire resistant cable jacket. In simple terms, the cables buy time in critical situations, allowing essential systems to operate and potentially help evacuate people in a fire emergency.

Applications of Fire Resistant Cables

Now, we’ll explore the various fire resistant cable applications where cables are indispensable for ensuring continued protection and functionality.

  • Emergency Lighting

Fire resistant cables maintain an emergency lighting system during a fire. It improves convenience by providing illuminated pathways for safe evacuation. This improves overall safety at critical times.

  • Fire Alarm Systems

When in a dangerous situation, the first alarm cannot be ignored. Fire resistant cables protect the functionality of the system and provide continuous monitoring and alarms. This emergency response facilitates rapid evacuation of people.

  • Smoke evacuation systems

Often, the visibility of a fire scene is low and breathable air is scarce. Fire resistant cabling is put into use to power smoke evacuation systems. As a result, smoke can be continuously reduced and air quality improves, contributing to safer evacuation.

  • Critical infrastructure

Fire resistant electrical cables safeguard electricity and communication lines in important buildings, including hospitals and emergency command centers. In times of crisis, the cables provide uninterrupted vital services, increasing the effectiveness of life-saving operations and assisting rescue missions.

Types of fire resistant cables

Fire resistant cables find application across various uses. Therefore, different categories have been created for different applications. Each category has specific performance characteristics. The following are some common fire resistant cables:

  1. Cross-linked polyethylene (XLPE) insulated cables: XLPE cables are constructed to provide higher current-carrying capacity with significant fire resistance.
  2. LSZH (Low Smoke Zero Halogen) Cables: LSZH cables limit smoke release at high temperatures. They improve visibility and reduce the release of harmful gases in fires.

What is LSZH Cable and Why LSZH is Better Choice?

Are you in the market for LSZH cable but feeling overwhelmed by all the options? LSZH (Low Smoke Zero Halogen) cable is a type of electrical cable known for its safety features in case of a fire. But with so many choices available, it can be hard to know which one is right for your needs. …

3. MICC (Mineral Insulated Copper Clad Steel) Cables: MICC cables consist of single or multiple copper conductors. The copper jacket is filled with magnesium oxide or other inorganic materials. They remain stable even at high temperatures.

4. Fire Survival Cables: The cable type assures electrical circuit integrity for a specific duration during fires. At elevated temperatures, the conductors trigger insulation to create a protective barrier, halting fire spread.

Also, many people often confuse Flame retardant with fire resistant cables. In the next section, we will explore difference between flame retardant and fire resistant cables to further understand the nuances of their uses and meanings.

Flame retardant vs fire resistant cables

The terms ‘flame retardant’ and ‘fire resistant’ are often used interchangeably but represent distinct capabilities. Their differences significantly impact  how they perform under fire conditions, affecting everything from fire spread to operational integrity during emergencies.

What is the difference in the construction of the cables?

The insulation of fire-resistant and flame-retardant cables is different in thickness. The insulation of refractory wires is thicker than that of flame retardant cables. Therefore it is more suitable for long-term application.

How Do They Contribute to Safety?

Flame retardant cables significantly increase safety by reducing the risk of fire spreading. Flame retardant cables prevent the rapid spread of flames. This means that it can control accidents and total emergencies. However, do they ensure the operability of critical systems in the event of a fire?

Fire resistant cables take safety to another level by limiting the spread of fire and also securing the operability of specific critical systems even when directly exposed to flames. This continuous operation is vital in life-saving situations. It allows for the safe evacuation of building occupants and enables emergency services to perform their duties efficiently.

Is There a Difference in Applications?

Flame retardant cables find widespread application across residential, commercial, and industrial settings, particularly prioritizing fire containment between compartments. However, their versatility across all applications remains a question.

Fire resistant cables are crafted explicitly for emergency lighting, fire alarm systems, and smoke evacuation systems. It is primarily employed in critical locations like hospitals, theaters, and high-rise buildings. In these environments, the reliability of operation during emergencies can even be life-saving.

Understanding these distinctions clarifies the selection criteria for either type based on the specific requirements of a building project. It emphasizes the importance of choosing the suitable fire resistant cable for the right application. The ultimate in improved safety and compliance with regulatory fire resistant cable standards.


Selecting the appropriate cable for any purpose is a crucial choice with significant safety ramifications. Comprehending the significance and characteristics of fire-resistant cables compared to other types is vital for individuals requiring cables. Whether in commercial, industrial, or residential environments, Fire-resistant cable uses the importance placed on safeguarding lives and property in the event of a fire.

What temperature is fire resistant cable?

Fire-resistant cables temperature maintain circuit integrity in the 750°C to 950°C range. Even in hazardous fire situations, operational reliability is assured.

How do you make a cable fire resistant?

For the cables to be fire-resistant, materials such as Low Smoke Zero Halogen (LSZH) are used in the insulation and sheath layers, which are not easily combustible and produce very little toxic fumes. The fireproof coating is designed with strict adherence to fire safety standards.

What is fire resistant cable material?

Key materials for fire-resistant cables include Low Smoke Zero Halogen (LSZH) compounds for insulation and jacketing, which significantly reduce smoke and toxic gas emissions. In addition, mica tape or xlpe insulation is often wrapped around the conductors for its excellent heat resistance.
