With the widespread adoption of information systems, various work environments and households have begun to integrate them. As a result, structured cabling systems have evolved from being a novel invention just 20 years ago into commonplace information-system transmission cables deeply embedded in people’s daily lives. Now that people can establish stable and reliable structured cabling systems, whether these systems can withstand external intrusions and prevent potential hazards to the outside world has become a new focus of public concern.

In modern society, people are increasingly reliant on fire—and at the same time, they are becoming more and more vulnerable to its hazards. As a result, the fire resistance of building materials, including those used in integrated cabling systems, has become a topic of growing concern.

　　External fire can damage the structured cabling system, causing transmission interruptions. On the other hand, the structured cabling system can generate a certain amount of harmful gases and smoke in flames, which may contribute to the spread of the fire to other floors or rooms.

　　The fire department stated that approximately 85% of fatalities in fires are caused by poisoning from harmful gases produced during the blaze, suffocation due to dense smoke, or inability to escape because the escape routes are obscured. Given the large number of integrated cables within buildings—far more than the variety of individual cables—the issue of fire resistance has begun to emerge as a key consideration in assessing system performance.

　　 Fire-resistant cable The degradation temperature of these wires is significantly higher than that of conventional PVC and PE cables. For example, the decomposition temperature of typical PVC materials is around 160 degrees Celsius, whereas the decomposition temperature of CMP-grade cable jackets made with fluoropolymer materials can exceed 400 degrees Celsius—far higher than the decomposition temperature of standard PVC materials, which is about 160 degrees Celsius. Thus, at the very onset of a fire, Fire-resistant cable The temperature of the wires has not yet reached their decomposition point (current kite strings do not spontaneously combust). Therefore, high-performance internal combustion engine wires will not release toxic gases or smoke, nor will they emit significant heat, giving people more time to escape. Currently, integrated cabling manufacturers have long since embarked on a path of global sales. Major integrated cable companies offer both high-flame-retardant and low-flame-retardant, halogen-free cables; some companies even produce fire-resistant cables that simultaneously meet both low-flame-retardant, halogen-free and high-flame-retardant requirements.

　　Europe has introduced the EN50289-4-11 standard, which is stricter than the CMP standard, and has developed specifications applicable to various... Fire-resistant cable The CPD series boasts high R&D standards. One can imagine that if low-flame-retardant, halogen-free (halogen-free) materials are combined with high-flame-retardant ones, future buildings... Fire-resistant cable It doesn't decompose easily, and even if it does decompose, it won't release large amounts of toxic gas or smoke. It can be said that this is already the long-sought-after goal in the integrated cabling field today.

　　In China, environmental protection has become a key consideration for people. Low-smoke, halogen-free cable manufacturing equipment is also inexpensive and does not require specialized toxic-gas treatment facilities. As a result, the development of low-smoke, halogen-free technology has far outpaced that of high-flame-retardant technologies (such as CMP and LCC).
