Blackburn PCSL2 COMP SLEEVE 2 PIGTAIL 2-1 CU

The PCSL2 is a compression reducer: an aluminum sleeve with a pre-attached copper pigtail. You compress the sleeve onto the larger conductor, and the smaller tinned copper pigtail comes out the other end so you can land it on a lug, connector or tap sized for the smaller wire. It handles two conductors and is rated to 35 kV, so it belongs in medium voltage work, not general branch circuit wiring.

The copper pigtail measures 6-3/8 inches, and the aluminum sleeve itself is 3 inches long. Plan your splice window around that: roughly 6-3/8 inches of flexible tinned copper to route into your lug or connector, plus a 3 inch compressed barrel on the cable end.

No insulation is supplied. The PCSL2 is a bare compression sleeve with a tinplated copper pigtail, so on 35 kV cable you provide the insulating and jacketing system yourself, whether that's tape, a splice kit or heat shrink rated for the cable.

Compression only. The sleeve is crimped with a hydraulic or battery compression tool and the correct die for the barrel, so there are no set screws and nothing is field-adjustable once it is pressed. Have the tool on site before you cut the cable.

The aluminum barrel is what goes on the aluminum conductor, and the pre-attached copper pigtail, tinplated, is what you land on the copper side. That keeps the aluminum-to-copper transition factory made inside the fitting instead of relying on a field joint between the two metals.

Sold each. Order one PCSL2 per termination you are making, and remember it handles two conductors per sleeve.

Manufacturer part number is PCSL2, brand Blackburn, described as a 2 pigtail compression sleeve for 2-1 copper. Country of origin is Mexico, which is what most public and institutional submittals ask for alongside the MPN.
