Blackburn PKL31-1 – Frequently Asked Questions
1) What conductor size does the Blackburn PKL31-1 pigtail compression sleeve take?
The PKL31-1 is a 1/0 compression pin terminal. The aluminum sleeve crimps onto the 1/0 cable and a copper pigtail comes pre-attached at the other end, so you land the smaller tinned pigtail where the 1/0 will not fit.
2) Can I use a PKL31-1 pin terminal on a 35 kV cable termination?
Yes. The PKL31-1 carries a 35 kV voltage rating, so it is suited to medium voltage cable work up to that class. It ships bare, with no insulation on the sleeve, so the joint has to be insulated in the field with the appropriate tape, tubing or termination kit.
3) Is the PKL31-1 rated for aluminum-to-copper transitions?
That is exactly what it does. The body is an aluminum compression sleeve with a tinplated copper pigtail already attached, so it reduces a 1/0 aluminum or copper run down to a smaller copper tail for equipment lugs. The tin plating on the pigtail is what keeps the dissimilar-metal contact in check.
4) What are the pigtail and sleeve dimensions on the Blackburn PKL31-1?
The pigtail measures 21/64 inch by 6-1/4 inches, and the aluminum sleeve is 3-1/2 inches long. Add those together when you are checking whether the assembly clears inside a transformer throat, switchgear cabinet or splice box before you crimp.
5) Does the PKL31-1 crimp on, or is it a mechanical set screw connector?
Compression only. The sleeve is installed with a hydraulic or battery crimp tool and the correct die for 1/0; there are no set screws and it is not reusable once compressed.
6) Is the Blackburn PKL31-1 sold individually or in a bag?
Sold each. Order one per cable end you are terminating, so a two-conductor transition needs two.
7) What is the exact part number and country of origin for this Blackburn pin terminal?
Manufacturer part number PKL31-1 from Blackburn, made in Mexico. Use the full PKL31-1 designation when matching a spec, since the series covers several conductor sizes.
