式求得：(外径相同)
Because this content is too long and very tedious for writing，therefore the reference data in Tables 5 - 9 are the most com-
monly used and universal types and specifications，i．e．，YJ V，YJ V22．If you want the weight of YJ LV，YJLV22，you can
find out according to the following formula：(the overall diameter is the same)．
WL=Wcu-S·K(ρcu-ρL)
