In the process of cable selection, flame-retardant cables and fire-resistant cables have become the first choice for many engineers and safety experts due to their excellent performance in fires. However, there is a significant difference in the performance of the two in terms of security. The Pearl River Cable will compare the safety performance of flame retardant cable and fire-resistant cable in fire in detail to help readers better understand their advantages, disadvantages and application scenarios.

1、 Safety performance of flame-retardant cables

1. Prevent the spread of flames

The most significant characteristic of flame-retardant cables is their ability to prevent flames from spreading along the cable. They use flame-retardant materials and designs to prevent cables from becoming channels for fire to spread even under high temperatures and open flames. This is particularly important in the early stages of a fire, as it can effectively slow down the spread of the fire and buy valuable time for personnel evacuation and firefighting rescue.

2、 Safety performance of fire-resistant cables

1. Maintain power transmission

Fire resistant cables can maintain power transmission for a certain period of time under high temperature and flame conditions. This feature is particularly important for critical equipment and systems, such as fire pumps, elevators, emergency lighting systems, and alarm systems. In a fire, maintaining the normal operation of these devices can greatly improve the safety of buildings and the efficiency of personnel evacuation.

2. High fire resistance capability

Fire resistant cables can maintain functional integrity in flames for a certain period of time, typically ranging from ten minutes to two hours. This is crucial for long-term fire rescue and safe evacuation, ensuring that critical systems can operate normally throughout the entire fire process.

3、 Comprehensive comparison

1. Different fire prevention mechanisms

Flame retardant cables mainly reduce the spread of fire by preventing the spread of flames, while fire-resistant cables ensure the operation of critical systems by maintaining power transmission. The fire prevention mechanisms of the two are different and applicable to different safety requirements.

2. Differences in application scenarios

Flame retardant cables are suitable for scenarios that require prevention of fire spread, such as ordinary commercial and residential buildings. Fire resistant cables are more commonly used in critical facilities that require power transmission during a fire, such as hospitals, subways, tunnels, etc.

3. Complementarity of safety performance

In some places with high safety requirements, flame-retardant cables and fire-resistant cables are often used in combination. Through this complementary approach, the overall fire performance of buildings can be maximized, preventing the spread of fire while ensuring the operation of critical systems.

Flame retardant cables and fire-resistant cables have their own safety performance in fires, and they provide protection for buildings and personnel through different mechanisms. Understanding their characteristics and applicable scenarios can help engineers and safety experts make more informed decisions in cable selection, thereby improving overall fire safety.
