What is fireproof cable? What are the domestic and international manufacturers of Fireproof Cable?

A. What is fireproof cable? Fire rated cable is a specially designed cable that maintains electrical function and stops the spread of fire in case of fire. Fire rated cables are a necessary safety requirement in many applications, especially in public places such as residential buildings, hotels, hospitals, schools, shopping malls and offices. The main feature of fire resistant cables is their high fire resistance, i.e. they can maintain power transmission for a long time in case of fire while reducing the spread of fire. Conventional cables usually use materials such as polyvinyl chloride (PVC) or cross-linked polyethylene (XLPE) as insulation and sheath materials, which can easily burn in a fire and release large amounts of toxic gases and smoke. Fire-resistant cables utilize a special polymer material, such as Low Smoke Zero Halogen (LSZH) materials, which do not burn in a fire and release very low amounts of harmful gases. In addition, fire-resistant cables use special designs, such as flame retardant and oxygen barrier layers, to improve their fire resistance. Definition of Fire-Resistant Cable Fire-resistant cable is a cable product that is able to maintain its normal electrical performance under certain fire conditions and produces a small amount of toxic and harmful gases and smoke during combustion. Fireproof cable is to meet the cable transmission performance at the same time, improve its fire, heat, wear, water, corrosion, oxidation and other characteristics, to ensure that the power system in the event of a fire will not exacerbate the fire, so as to ensure the safety of people's lives and property. Second, the classification of fire-resistant cable according to different use of the environment and requirements, fire-resistant cable can be divided into a variety of types. According to the different uses, fire cables can be divided into the following types: fire power cables: mainly used for power systems, power transmission, distribution and lighting and other areas, such as automatic fire alarm systems, emergency lighting systems, fire pump room. Fireproof communication cable: mainly used for transmission and control of communication system, such as security monitoring system, fire monitoring system, emergency call system, etc. Fireproof control cable: mainly used for transmission and control of control system, such as fire protection system, fire smoke exhaust system, etc. According to the different materials, fireproof cable can be divided into the following types: Flame retardant fireproof cable: it is not easy to burn during fire, and can effectively prevent the spread and expansion of fire. Low-smoke halogen-free fireproof cable: does not produce toxic and harmful gases and smoke in case of fire, and can protect people's lives and property safety. Fire-resistant fireproof cable: It can maintain its electrical performance in high temperature environment, and has the characteristics of high temperature resistance, heat resistance and corrosion resistance. Fire-resistant cable has a wide range of applications, including the building's power distribution system, communication system, automatic control system, fire protection system, elevator and so on. Here are some typical application scenarios: Residential buildings: Fireproof cables are widely used in the power distribution system, lighting system, fire control system and elevator of residential buildings to improve the fire safety performance of residential buildings. Commercial and office buildings: fire-resistant cables in commercial and office buildings are mainly used in lighting, power and communication systems to ensure the reliability and safety of communication and power supply systems within the building. Hospitals and schools: fire cables in hospitals and schools in the application of mainly involved in the power system, communication systems, automatic control systems and fire protection systems to ensure the safety performance of these public places. Industrial facilities: Fireproof cables are widely used in industrial facilities for power systems, control systems, communication systems and fire-fighting systems to ensure the safety performance and normal operation of industrial facilities. Fireproof cable is a very important type of cable.
