Blackburn SATC 400 AL TAPERED SPLICE WIRE SIZE 400

The SATC 400 is sized for 400 conductor, and it splices two conductors end to end (one in each barrel). It is a tapered aluminum compression splice, 5-1/2 inches long overall, so allow that much straight run plus bending room in the enclosure or manhole before you crimp.

Yes. The SATC 400 ships bare with no insulation on the body, so the joint is not insulated when the crimp is done. You finish it in the field with tape, heat shrink, or a cold shrink or molded cover sized for a 400 splice, or install it inside an enclosure where bare hardware is acceptable.

Compression only. There are no set screws, so you need a hydraulic or battery crimp tool with dies matched to the barrel for a 400 aluminum splice. If you want to make the joint with a wrench instead, you want a set-screw or mechanical splice, not this one.

The SATC 400 is built to ANSI C119.4, the standard for connectors used on underground and other insulated or bare conductor splices. That is the line utility and institutional specs usually call out on submittals for compression splices.

It is an aluminum-bodied tapered splice, bare with no insulation. Aluminum compression connectors of this type are commonly rated AL9CU for both aluminum and copper, but that dual rating is not something we state for the SATC 400, so order it for the aluminum 400 splice it is described for and use a connector marked for copper where copper is the conductor.

Country of origin is the United States, which is what government, school, and utility procurement usually needs documented on a domestic-preference job. The part number to list on the submittal is Blackburn SATC 400.

No. It is a two-conductor in-line splice, one conductor into each end, so it joins a run rather than branching from it. For a branch off an unbroken main you need a tap or H-tap compression connector instead.

The tapered body steps down from the crimp barrels toward the center, which keeps the overall bulk down and gives a smoother profile to tape or shrink over. On a 400 aluminum splice that matters when you are covering the joint by hand in a tight pull box.

Each. One SATC 400 splice per unit, so a two-conductor repair takes one piece per conductor being joined. Order count accordingly on a multi-conductor feeder.
