Cable crimp types for H.V or L.V.
(OP)
I have been supplied with two types of crimp "lugs" for H.V copper cables. Does any "collar" length suit or do H.V crimps require longer compression areas?
Thanks & All the bst in the New Year.

There are short- and long-barrel hydraulic-tooled compression terminals, but use of one or the other for certain voltage levels is more a matter of engineering specification and localized custom. I believe typically they are rated up to 35kV under UL 486A.
A variation has externally beveled at the barrel end to facilitate void-free taping with MV-termination materials. Example 64200-/64800-/64400-series http://tn

Greater than 35 kV, I think you're on your own. That is, the market is so small, you're essentially on your own (other than your colleagues here)

I have always wondered why lugs come with a voltage rating? I realize there is a reason, however, what is it? How can one piece of copper (lug) have a voltage rating on its own? Excuse my ignorance.

The 35 kV rating has something to do with UL486A, but I don't have the standard.
