Do you know what is fireproof cable?

• Fireproof cable

America and Europe exported fireproof cables . At present, the popular fireproof cables mainly include UL series flame-retardant cables and flame-retardant low-smoke halogen-free cables. This kind of cable mainly come from the Americas and Europe. Due to the incompatibility of fireproof cable standards in the Americas and Europe, the fire prevention ideas are very different. Therefore, Party A and the design institute are in a passive state when choosing products.

In the end, it is often chosen according to the actual situation of funds. In the cable standard, there is also a kind of fire protection standard. This standard is “line integrity”. Its goal is that the cable can still keep the line open in the fire scene. So that power and information can still be transmitted normally. Therefore, cables that meet the series integrity requirements are also fireproof cables.

• BBTRZ cable

BBTRZ cable is the second-generation product of mineral cables. In addition to the advantages of the first generation of rigid (hard) mineral cables. Such as fire protection, explosion-proof, temperature resistance, and large current carrying capacity.

It also has the following characteristics:

1. multi-core
2. fixed-length production
3. no intermediate joints
4. flexible structure
5. easy to bend
6. no special terminals
7. no worries about accessories
8. suitable for various laying methods

• Fireproof Cable Standard

At present, there are two types of common fireproof cable levels:

1. Chinese standard: at 750°C, it can still continue to work for 90 minutes (E90).
2. German standard: at 800-850°C, it can still work for 180 minutes (FE180).

Although the latest Chinese data center standard requires all cables to use CMP-level integrated wiring cables. They can still transmit data normally without damage at a temperature of 500°C. They can leave a certain amount of time for emergency backup of information.

However, it cannot meet the requirements of the national standard for fire-resistant cables. And it cannot be called a fire-resistant cable.

• Development trend of fireproof cables

1. Product technology has entered the era of standardization.There are rules and laws to follow for fire and flame retardancy.  It is widely used in the industry system, industry standards are the foundation of industry and enterprise development. And product technical standards are the effective guarantee of product quality. With the development and maturity of China’s wiring industry, the national competent authorities are vigorously promoting the standardization of the wiring industry. At present, the formulation of technical standards for fire-resistant and flame-retardant cables has been included in the work plan for the next stage.
2. Fire prevention and flame retardant continue to heat up, and leading companies have emerged to occupy the mainstream market. At present, leading companies in the domestic fire-resistant and flame-retardant industry have begun to emerge. The domestic fire-resistant and flame-retardant cable market has formed a number of mainstream companies. Through continuous product extension and channel expansion, these companies have continuously improved corporate management and team building. Whether it is the influence of the brand, the overall improvement of product quality, or the standardization of services, it has been more and more accepted and affirmed by the industry and users.
3. The attention of users has been continuously strengthened. And the service concept is being improved. The important role of fire-resistant and flame-retardant cables in engineering applications is becoming more and more important. Everyone recognized that future fire-resistant and flame-retardant cable manufacturers are not limited to simple product offerings at the current stage. But it will also continue to extend the product chain while strengthening service concepts to provide users with full-line compatible products. Products, and provide full technical support and services for the correct and reasonable use of products, which will surely become the market development trend of the fire and flame retardant cable wiring industry.
