Breakdown voltage depends on the thickness of the covering,
which can be of 3 types: Grade 1, Grade 2 and Grade 3.
Higher grades have thicker insulation and thus higher breakdown voltages.
Thanks for eloborating about "Google knows". Apparently UEW class 1 and 2 are corresponding to the JIS specification quoted e.g. in the Infantron catalog. The most "lightweight" class 3 seems to have been added.
