Fire-resistant cable, as its name suggests, is a cable with excellent fire resistance. In the event of a fire, it ensures the integrity of the line and prevents the fire from spreading, thus buying valuable time for evacuation and fire-fighting efforts. Fire-resistant cables are widely used in all kinds of important facilities and occasions, such as buildings, power stations, chemical enterprises, etc. They have become an important part of fire safety in modern society.
The key to manufacturing fire-resistant cables lies in their unique process and structure. Firstly, in the selection of conductor materials, copper or aluminum conductors with low melting point and high electrical conductivity are used to ensure that the electrical performance of the cable remains unchanged under the high temperature of fire. Secondly, in terms of insulation layer materials, mineral oil, synthetic rubber and other materials with excellent fire-resistant properties are used so that they can maintain good insulation properties under fire conditions. In addition, the sheath material of the cable is also vital, generally using fire-resistant coatings, fire-resistant coating materials, etc., in order to improve the fire resistance of the cable.
How fire-resistant cable fire performance, but also through strict testing standards to test. China’s test standards for fire-resistant cable mainly includes vertical combustion test, radial combustion test, fire resistance time test, etc., only to meet the requirements of these standards, the cable can be called fire-resistant cable.
In practical applications, fire-resistant cables perform satisfactorily in important facilities and occasions. For example, in high-rise buildings, fire-resistant cables can ensure the normal operation of critical equipment such as elevators and fire pumps when a fire occurs; in chemical enterprises, fire-resistant cables can prevent fire accidents from causing serious production accidents and safeguard the lives of employees.
As a big country of cable production and application, China’s fire-resistant cable industry has developed rapidly in recent years. With the progress of science and technology and the improvement of market demand, the future of China’s fire-resistant cable industry will move towards the direction of higher performance, more intelligent and more environmentally friendly.
In the purchase and use of fire-resistant cable, there are some precautions to follow. First of all, when purchasing to choose the regular manufacturers of high-quality products to ensure the performance and quality of the cable; secondly, in the process of use, to follow the relevant installation specifications, to avoid damage to the cable, affecting its fire performance. In short, only the correct purchase and use of fire-resistant cable, in order to give full play to its important role in fire safety.
In short, fire-resistant cable as a cable with excellent fire performance, in our country all kinds of important facilities and occasions have been widely used. Understand its manufacturing process, structural characteristics, fire performance and testing standards, for the purchase and use of fire-resistant cable is of great significance. In the future development, China’s fire-resistant cable industry will continue to innovate to meet the society’s growing demand for fire safety.
Tester specializes in the research, development and production of various types of fire-resistant cables, which are widely used in metallurgy, thermal engineering, petroleum, chemical industry, natural gas and other special environments, as well as electrical installations that require special fire resistance properties.
