Is it mandatory to use multiple strands for 10 square millimeters and above?
Thread Content
Must cables of 10 square meters and above be multi-strand? I think there’s such a rule; the specifications state that at least 6 strands should be used?
Yes, according to relevant specifications, cables with a cross-sectional area of 10 square millimeters or more typically require a stranded construction. Specifically, the standards generally require that cables with a cross-sectional area of 10 square millimeters or more should have a conductor structure of at least 6 strands or more. Such a design can improve the flexibility and load-bearing capacity of the cable, ensure low resistance and good transmission performance, and meet the requirements for transmitting large currents. .
