Characteristics and Structure of Fire-Resistant Cable
Fire-resistant cable is a special type of cable designed to serve the purpose of minimizing risks when a fire or explosion occurs. So, what are the outstanding characteristics of this type of cable? What is the characteristics and structure of fire-resistant cable like? Refer to the article below. LION will help you answer the information in detail!
Characteristics of Fire-Resistant Cable
Fire-resistant cable is a type of cable specially designed to operate in high-temperature environments and with fire for a certain period. Below are the main characteristics of this type of cable for your reference:

Special Structure
Fire-resistant cable basically has components similar to ordinary electrical cables. However, the only difference lies in the fact that the insulation layer or the inner sheath has been added with fire-resistant materials. This difference enables the cable to prevent the spread of fire and maintain stable operation.
Good Heat Resistance
Fire-resistant cable has the ability to withstand higher temperatures than ordinary cables. On average, the cable can endure temperatures from 750°C to 950°C. Therefore, this type of cable is often used in environments with a high risk of fire or explosion, such as factories, export processing zones and chemical processing facilities.
Preventing the Spread of Flames
One of the most outstanding characteristics of fire-resistant cable is its ability to prevent flames from spreading. The flame will travel along the burning cable to prevent the fire from flaring up. This helps extend the time to handle incidents and enhances the effectiveness of the fire prevention system.

Structure of Fire-Resistant Cable
Fire-resistant cable comes in two types: single-core and multi-core cables. Basically, the structure of the cable includes the following components:
Conductive Core
The core is typically made of conductive metals such as copper or aluminum. However, copper cores are more durable due to their ability to withstand higher temperatures. The core is usually wrapped with mica tape on the outside to enhance the insulation efficiency of the conductor.
Fire-Resistant Layer
The fire-resistant layer is located outside the core. It is typically made from materials with high fire resistance and heat tolerance, with mica being the most common. Usually, the conductive core is wrapped with a mica layer around it. The length and thickness of the mica must ensure the formation of an effective protective barrier to prevent electrical leakage or unsafe breakage.
Insulation Layer
The insulation layer of the cable is the defense line following the fire-resistant layer. It is typically made from polyethylene. This type has both fire-resistant and insulating properties, optimally protecting the cable and effectively extending its lifespan.
When Should Fire-Resistant Cable Be Used?
During a fire, ordinary electrical cables cannot withstand high temperatures. This leads to melting and short-circuiting, causing dangerous electrical fires in the structure. Therefore, using fire-resistant cables in projects is considered a solution to ensure safety and maintain stable operation for the electrical system.
In practice, fire-resistant cables are often used for critical and essential systems in structures, such as:
- Emergency alarm systems, such as fire alarms, emergency lighting systems, public address systems, smoke extraction and automatic sprinkler systems.
- Fire-resistant cables are also used in the electrical systems of critical structures like hospitals, data centers, communication systems, airports and train stations.
- Fire-resistant cables are also used in the electrical systems of industries with hazardous working environments, such as oil rigs, chemical plants and areas with radiation.
