Fireproof cable

Fire-proof cables, imported from America and Europe, are widely used at the present stage, mainly including UL series flame-retardant cables and flame-retardant low-smoke halogen-free cables. The imported products are mainly from the Americas and Europe. Because the standards of fireproof cables in the Americas and Europe are not compatible with each other, the fire prevention ideas are very different. Therefore, Party A and the design institute are both in a passive state when selecting products. Each has its own reason. Finally, the selection is often based on the actual situation of the capital. Among the cable standards, there is also a class of fire protection standards, called "line integrity" standards. Its goal is to keep the cable unblocked in the fire, so that power and information can still be transmitted normally. Therefore, cables that meet the integrity requirements of the series are also called fire-proof cables.

BBTRZ cable

BBTRZ cable is the second generation of mineral cable. In addition to the advantages of the first generation of rigid (hard) mineral cable in terms of fire protection, explosion protection, temperature resistance and large current carrying capacity, it also has the following characteristics: it is not easy to absorb moisture and has more stable insulation performance, can be produced with multi-core and fixed length, without intermediate and indirect head, flexible structure, easy to bend, no need for special terminal, no worries about accessories, and is suitable for various laying methods, General electrical personnel can follow the conventional cable laying method.

Standard for fire-proof cables

At present, there are two kinds of common fireproof cables: Chinese standard: at 750 ℃, they can still work for 90 minutes (E90). German standard: at 800-850 ℃, it can still work for 180 minutes (FE180). Although the latest Chinese data center standard requires all cables to use CMP grade generic cabling cables, that is, they can still be undamaged at a temperature of 500 ℃, transmit data normally, and leave some time for emergency backup of information, but they cannot meet the requirements of the national standard for fireproof cables, which cannot be called fire-resistant cables.

Development trend of fireproof cable

1、 The product technology has entered the era of standardization, and there are rules and regulations to follow for fire prevention and flame retardance. With the continuous improvement of social security and system security requirements, through the extensive publicity, promotion and cooperation of the government, industry and enterprises, special cable products with high performance, efficiency and safety will be widely used in all industries and systems, as in the western developed countries. Industry standards are the basis of industry and enterprise development, and product technical standards are the effective guarantee of product quality. With the growing development and maturity of China's cabling industry, the national competent department is vigorously promoting the standardization construction of the cabling industry. At present, the formulation of the technical standards for fire-resistant and flame-retardant cable products has been included in the work plan of the next stage. 2、 Fire prevention and flame retardancy continue to rise, and leading enterprises have emerged and occupied the mainstream market. At present, the leading enterprises in the domestic fire retardant industry have begun to take shape. The domestic fire retardant cable market has formed a number of mainstream enterprises. These enterprises have been increasingly accepted and affirmed by the industry and users through continuous product extension and channel expansion, and through continuous improvement of enterprise management and team building, whether in terms of brand influence, overall improvement of product quality, and service specifications. 3、 The importance of users has been continuously strengthened, and the service concept is improving. Through the joint efforts and publicity of the government, industry, engineering companies and manufacturers, the coexistence of high-end equipment and low-quality cables in the engineering system is becoming less and less. The important role of fire retardant cables in the use of the project is more and more truly recognized by everyone. The future fire retardant cable manufacturers are not only limited to the provision of simple products at this stage, but also will continue to extend the product chain, Strengthen the service concept, provide users with full-line compatible products, and provide full technical support and services for the correct and reasonable use of products, which will become the market development trend of the fire retardant cable and wiring industry. 4、 It is imperative to move towards internationalization. "To be a cable enterprise in the world and build an international national brand in China's cabling industry" has become the development goal and corporate mission of excellent enterprises in the industry at present.
