Y single-core unshielded thin-wall PVC insulated low voltage cable for FLRY road vehicles
FLRY-AA conductor structure (see Table 1), normal stranded conductor structure, the number of single lines is odd, one single line is arranged in the center of the
conductor cross section.
FLRY-BB conductor structure (see Table 2), unconventional stranded conductor structure.
