In construction projects, power systems, and public facility construction, wires and cables not only play an important role in transmitting electrical energy, but their combustion performance is also receiving increasing attention. Especially in densely populated areas, commercial complexes, hospitals, schools and other buildings, the combustion performance of wires and cables has become one of the important reference factors when selecting.

So, how are the combustion performance levels of wires and cables classified? What are the differences between different levels? Today, the Pearl River Cable will give you a brief introduction.

What is the combustion performance of wires and cables?

The so-called combustion performance refers to the combustion characteristics of wires and cables when exposed to a fire source, including whether they are easily ignited, the speed of flame propagation, the release of smoke, and whether they can self extinguish after leaving the fire source.

It should be noted that combustion performance does not mean that wires and cables will not burn, but rather measures their impact on the spread of fire under specific conditions and their performance in a fire environment.

Common classifications of combustion performance

1. Ordinary wires and cables

Ordinary wires and cables mainly meet the needs of power transmission, and their insulation materials may burn when exposed to open flames, making them more suitable for electrical scenarios in general environments.

2. Flame retardant wires and cables

Flame retardant cables are a common product type in current engineering construction.

Its characteristic is that after the fire source is evacuated, it can to some extent suppress the continued spread of flames and reduce the risk of fire spreading along the route. According to relevant standards, flame retardant performance is usually classified into different levels, such as A, B, C, D, etc. Different levels correspond to different combustion test requirements and application scenarios.

3. Fire resistant wire and cable

There is a difference between fire-resistant cables and flame-retardant cables.

Flame retardant focuses on slowing down the spread of flames, while fire-resistant cables emphasize the ability to maintain normal operation of the line for a specified period of time in a flame environment, providing power support for key systems such as firefighting equipment and emergency lighting.

4. Low smoke halogen-free wire and cable

Low smoke halogen-free cables produce less smoke during combustion and release relatively less corrosive gases, making them commonly used in places with certain requirements for air environment and equipment protection.

Pay attention to product quality when making purchases

In addition to the combustion performance level, the quality of the conductor material, insulation layer, production process, and whether the product meets relevant standards are also important factors that affect the effectiveness of the use of wires and cables.

As a wire and cable manufacturer, the Pearl River River Cable has continued to focus on improving product quality and technology, constantly improving its product system, and providing corresponding wire and cable product choices for different application scenarios such as home decoration, engineering construction, and industrial support.

With the continuous improvement of building fire safety requirements, the combustion performance of wires and cables has become one of the important indicators of industry concern. Understanding the performance characteristics and scope of application of different products can help make more reasonable choices during project construction and product selection, providing support for the stable operation of the power system.
