The flame-retardant nature of the cable in the case of multiple dense configurations should be by the “burning test method for bundled wires and cables”. As well as the cable configuration, the need to prevent catastrophic accidents and economic and reasonable principles, to meet the requirements of the appropriate category.

The Flame Retardant Grade of Cable is Related to the Safety of Life. Have You Chosen the Right One?
With the development of wire and cable production technology, there are more and more types of wires and cables. Even cables of the same kind have different specifications and grades. However, their requirements for fire resistance and flame retardancy have been ignored by people, and their grades are not up to standard, which easily lays huge hidden dangers for fires. If all the highest levels are used, there will be a little “waste”. Then several elements of the flame retardant grade of wires and cables should be considered in the project engineering design? Here are some suggestions for you, hoping to help you.
