I work for a company that makes Static Frequency Converters for aircraft, and the input cables required 125A Commando's. Output required 400Hz, 3Ph w/interlock Anderson Plugs. We use Klauke crimpers for 70mm ferrules and 120mm2 copper ring terminal lugs. They're fantastic, crimp reliably, and much lighter to carry than cheaper alternatives.
I've never needed a ferrule larger than 16mm , so i assume aviation still use the tradition hole in brass and screw down method? Klauke, Cembre and Dubuis are the flagship crimpers.. cheap alternatives just not worth it
It does have a matching crimper for lugs review coming soon. Wait until you see the ferrules needed on a 125A plug (you can just see it in the thumbnail)
We certainly need to lug them on our boats that handle around 250A continuously. Then again.. we don't have any way to attached ferruled cables. only bolting.
but i still dont understand why not fit a ferrule that is the same colour as the cable ie terminating a 2.5m flex use blue ferrule on neutral and brown on live yet the colour codes show blue or grey for 2.5mm. doesnt seem right to me that all cables would have the same colour ferrule
I tend to use pin crimps on larger cables, the casing on those ferrules are thin and i've seen them deform and loosen over time, Klauke make some good gear.. batteries are made by bosch , well they are on the 18v kit, i went Cembre as batteries are made by Metabo and i already have Metabo metal munching tools and lugs are easier to get as Rexel stock all Cembre gear
"deform and loosen over time" means you didn't crimp it properly in the first place or they were very low quality ferrules. If you do it properly with the right ferrule, the copper cold welds to the ferrule itself from the amount of force applied
I never said i crimped them, haver been on jobs and seen the results of poor crimping, looking at the ferrules being used in the video, i doubt they're cold weld, the head of the crimper gives that away, interlocking leaves wouldn't give enough pressure to cold weld.. maybe the lads could cut one open... interesting to see
@@thattoolguy9432 it indeed cold welds at the sections which have been compressed the most, just not the whole way through the ferrule. You need to cut a clean cross section at just the right place to see it

Great feedback thanks 👍🏻

Heamar in the UK sells these for both international as well as in country use.
Now those are chonky ferrules!
Wouldn't cables that big normally use crimped lugs instead of screw-clamp terminals? Or maybe I've just been watching too much Jointech...
We use ferrules on cables up to 100mm in boards - in Australia...

@@efixx great to hear. We have a foot pump hydraulic lug crimper and it's a hassle to haul around.
Stay tuned - sounds like you'll love it!
NICE machine!
Apparently selling a child to pay a lovely Klauke crimper is frowned upon so I can't afford it. ☹
Pretend it’s for the x-box
Don't sell a child. Sell it's kidney 😉

Very nice sir
Nice!!

Hank and Chuck don’t use many ferrules

That's an air tight crimp not a cold weld, as it would still have voids
@@thattoolguy9432 there’s no voids in the cross sections of highest compression, it cold welds
What's the cable stripper please ?
Shut up and take my money 😤🤝
My fingers are hiding watching this.

Bit of context here - the cable in the thumbnail 50mm sq HO7RNF is nearly £50 a meter.
