How to choose the fireproof and flame retardant cables in the data center? The fireproof and flame retardant cables in the data center shall be selected according to the flame retardant grade.

When we select cables, the flame retardant characteristics of various cables should be selected from the test level of fire and flame retardant. We can not simply distinguish them by cable materials, let alone according to the requirements of power cables. Generally, flame retardant PVC and flame retardant LSOH are selected from materials, while CMP is selected from flame retardant grade. The reason for this comparison is that there are a large number of similar situations in the domestic industry, which equate materials with flame retardant grade. Therefore, I would like to emphasize once again that the selection of fire and flame retardant cables should be distinguished according to the grade of fire and flame retardant cables in a certain standard.

For example, if you want to use low smoke halogen-free flame retardant cables, you need to explain the test standards that your selected cables meet in terms of fire protection (for iec60332-1 or iec60332-3c, if you want to select cables with flame retardant PVC sheath, you need to specify which one is CMP, CMR and cm. Only in this way can you know what level the flame retardant performance of the cables you select has reached, so as to avoid selecting fire-resistant cables that do not meet the engineering requirements.

In addition, there are grade differences in the flame retardant characteristics of various flame retardant cables. In fact, some so-called flame retardant cables simply can not meet the flame retardant standards of any level. Therefore, in an important place such as the data center, it is necessary to clearly understand the flame retardant grades and characteristics of various flame retardant cables.

Before choosing products, you must know your data center, which level of data center it belongs to, what purpose it is used for, what special requirements, etc. in this way, you can choose the cable category according to the standard. Of course, if you don't follow the standard for other special reasons or to control capital investment, you want to choose a slightly lower grade fire resistance For flame retardant cables, cables that are closer to the requirements of wiring standards and pass flame retardant test shall also be selected.

The new data center standard tia942a of the United States has been adopted. From this, we can also know that although the higher the fire resistance and flame retardancy grade is, the better, many practical problems still restrict our use of high-grade flame retardant cables. Nevertheless, in generic cabling, especially in generic cabling of data center, before using a certain type of communication cables, designers and facilities should Workers and users should not forget to find out whether the fire and flame retardant characteristics of the cable are consistent with the actual requirements.
