Blackburn EXJ360A3279140 EXJ -EXTRA-FLEXIBLE, 90 DEGREE BEND

It's a flexible braided jumper used to carry current between two bus or equipment terminations that move relative to each other, such as switchgear, disconnect switches, and expansion or vibration points in a bus run. The braid is flat tin-plated copper with a 90 degree bend formed into it, and it terminates on 4-hole pads at each end. Blackburn builds it to IEEE/ANSI C37.34.

The cable length is 11 inches. That is the braid run itself, and because the connector is made with a 90 degree bend, the two terminal pads sit at right angles to each other rather than in line. If your two landing pads are parallel and facing, a straight EXJ braid is the right part instead of this one.

Yes. Each end of the EXJ360A3279140 is a 4-hole terminal pad, so the equipment bus or terminal it lands on has to be drilled for a matching 4-hole NEMA pattern. Two-hole pads will not accept it. Hardware to bolt it down is not part of the braid; order bolts, nuts, flat and Belleville washers separately to suit your pad thickness.

The conductor is tin-plated copper, and the tin plating is what makes it suited to outdoor and substation service, since it slows oxidation at the bolted interface and pairs with either copper or aluminum bus when used with the correct joint compound. It is manufactured to IEEE/ANSI C37.34, the standard covering high voltage air switches.

Braid flexes. Where two terminations move, from thermal expansion in a bus run, equipment vibration, or the travel of a switch blade, a rigid copper link transfers that stress straight into the bolted joint and the porcelain. A flexible flat braid absorbs the movement while keeping the current path short. The EXJ360A3279140 is the extra-flexible flat braid version with a 90 degree bend, for connections where the two pads are not on the same plane.

It is sold each, so one order quantity gets you one braid connector. On a three-phase switch or bus expansion point you will normally need three, one per phase, so multiply accordingly.

Country of origin is the United States. That matters on utility, federal, and Buy American funded projects where domestic origin has to be documented in the submittal package. The manufacturer part number to cite on that submittal is EXJ360A3279140.
