National standard fire-resistant cable grade B and B1 represent high-standard fire-resistant cable classifications.
They have strict specifications for the performance of cables in a fire. B1-grade cables must have good flame-retardant properties. Their flame-retardant effect can effectively delay the spread of fire. They will not quickly release a large amount of heat during combustion. This can reduce the impact of thermal radiation on the surroundings during a fire. The amount of smoke generated is strictly controlled within a certain range. Low smoke emission can provide a clear view for personnel evacuation. The content of toxic gases generated by cable combustion is relatively low.This reduces the risk of casualties from poisoning in a fire. They are made from special flame-retardant materials. These materials have good temperature resistance characteristics. They can maintain structural stability even in high-temperature environments. They can withstand a certain degree of external mechanical force. This ensures that they are not easily damaged during installation and use. The outer skin material has good anti-aging properties. It can be used for a long time without reducing fire-resistant performance. The manufacturing process requires strict quality control. There are strict standards from raw material selection.
Each process in the production process needs to be inspected. This ensures that every cable meets the B1 standard. It must pass professional fire-resistant performance tests. This includes tests such as burning speed and smoke production. Only after certification by an authoritative institution can it obtain the B1 mark. This grade of cable is suitable for places with high personnel density. For example, shopping malls, theaters, etc., to ensure personnel safety. It is also often used in the electrical systems of important buildings. For example, hospitals, schools, etc., which are related to important functions. It is also crucial for data centers and other places.
It can prevent fire from damaging key equipment. In industrial plants, it can reduce fire losses and effectively protect production equipment and materials. During installation, specific construction specifications must be followed. This ensures that the cable installation quality meets fire prevention requirements. The connection with other electrical equipment must comply with standards. This avoids fire hazards caused by improper connections. Daily maintenance is crucial for maintaining its performance. Regularly check the appearance and performance of the cable. Address any problems promptly to ensure safety. Compared with ordinary cables, the Price will be relatively higher.
But from the perspective of safety assurance, the cost-effectiveness is very high. National standard fire-resistant cable grade B1 provides safety protection.
