Interpreting wire type specifications on engineering drawings

[LickMyEyeball]

I have an electrical drawing which specifies a wired connection as 3# 10+ 3# 12v- Teck symmetrical.
What do all these numbers mean?

not really enough info the 10+ and 12v- look like voltage references ... 3#, no idea

how about a sharp and clear pic of what you are talking aboutDave

In my opinion, it could be:
3*10 awg+3*12 awg Teck cables
See [for Teck cable, for instance]:

However, I don't know what "v" signifies -may be "vertical"-and "symmetrical", also.
