With the continuous development of technology, cables play an increasingly important role in modern life. However, fire is a common safety hazard. In order to improve the safety performance of cables in fire, fireproof cable sleeves came into being.
1. Working principle of fireproof cable casing Fireproof cable casing is a protective casing used to cover cables. Its main function is to provide effective heat insulation and flame retardant protection in the event of a fire to protect the cable and its surrounding equipment from fire. Fireproof cable sleeving is usually made of high temperature resistant and flame retardant materials, which can effectively slow down the spread of flames and reduce the risk of fire.
2. Material properties of fireproof cable casing Common fireproof cable casing materials include polyolefin, inorganic fiber and gypsum. These materials have high fire resistance, remain stable at high temperatures, and do not release toxic or harmful smoke or gases. In addition, fireproof cable casing is also resistant to corrosion, acid and alkali, and ultraviolet rays, and can adapt to various complex working environments.
3. Application fields of fireproof cable casing Fireproof cable casing is widely used in construction, transportation, electric power, petrochemical and other industries. In the construction sector, fire-resistant cable sleeving is commonly used for cable protection in fire protection systems, electrical equipment and emergency evacuation routes. In the field of transportation, fireproof cable sleeves are often used in subways, tunnels, airports and other places to ensure reliable operation of cable systems in fires. In the power industry, fireproof cable sleeves are widely used in high-voltage transmission lines and substations to improve the safety performance of the power system.
4. Development Trend of Fireproof Cable Casing As people’s requirements for safety performance continue to increase, the research and development of fire-resistant cable sleeves is also constantly advancing. In the future, we can look forward to the application of more advanced material technologies and design concepts to provide more efficient and reliable fire protection. At the same time, the intelligent application of fireproof cable casing will also become a development trend, enabling remote monitoring and intelligent diagnosis of cable systems.
