Cable Lugs used on Flexible Cable
(OP)
Can normal cable lugs be used on flexible cables?
Crimp type lug: Burndy HYLUG YA35L
- listed for 550 kcmil, code conductor
Crimp type lug: Burndy HYLUG YA34L
- listed for 500 kcmil, code conductor
Cable type: Amercable Flexible Power Cable 4core x 535 kcmil
- Copper conductors flexible stranded to IEEE 1580 Table 11.

In my industry we have whats called telcoflex cable and for a 350kcmil conductor you use a 500kcmil compression lug.

If the flexible cable was 35 mm^2 then I'd use a 50 mm lug.

1 - The O.D. of the finely stranded cable is SLIGHTLY larger.
2 - The finely stranded wire has more strands (of course) and it is more of a challenge to get them all into the lug barrel. Bell mouth lug makes it easier.

On their LCDX Flex Conductor lugs for example they call out can be used with code conductors and flex conductors class G, H, I, K, M and Locomotive. They also list in the tables in their catalog a part number for the lug, then 3 columns next to it which tell what size Class/Locomotive/Code conductors it will fit/approved on. Then for my sanity, I always check the drawing where it shows the ID of the lug and then check the conductor diameter for the appropriate wire I've spec'd. Make sure you get the appropriate/approved crimping die set also..
Nothing worse than stripping a 750kcmil wire and finding it doesn't fit into the 35 dollar non-returnable compression lug you just bought. Wire birdcaging is not acceptable, neither is cutting strands till it fits... (seen it done many times though).
From what I've seen if you spec the correct wire and lug the bellmouth style is not needed at all. It also typically cost more too.

I've decided to get Burndy lugs specifically listed for flexible conductors. Catalog page is attached.

IEEE 1580 Table 11 lists conductor diameters for "Flexible Cables". This matches with the Amercable flexible cable that I have.
IEEE 1580 Table 10 lists conductor diameter for "Standard Class B cables". I assume this is the what is applicable for "normal non flexible cable".
Comparing the information in an Excel table (see attached) the diffference in conductor diamater:
- 600kcmil (Class B cable): diameter 0.893"
- 535kcmil (Flex cable): diameter 0.941"
--> Difference in diameter is just 0.048" or 1.2192mm which is really quite small!!
