In ZRB-DJYJVP-32-B-1*2*1.5, it is the 32-B part. What does B mean?
"B” indicates that the insulation layer of the power cable is made of cross-linked polyethylene material. .
32 with steel wire armor for B can be interpreted in two ways. One interpretation is that it refers to flame-retardant Class B; obviously, ZRB may also mean flame-retardant Class B. The other interpretation is that it refers to Class B conductors, which are what are commonly known as Category 2 conductors. For Category 5 conductors, the conductor resistance at the specified interface is different, and thus the current that can pass through them is also different
