Blackburn FBE2H150A1-17 XFLEX BRAID 2 9/16H 1/2X1.5 X 17 IN

It is a flexible braid jumper, 17 inches long, used to carry current between two bus or equipment pads while allowing movement. The braid construction is flat and extra flexible, so it absorbs thermal expansion, vibration, and switch or disconnect travel that a rigid bar or a solid conductor would transmit into the terminals. Typical use is switchgear, substation bus, transformer and disconnect-switch connections.

It is built to CEI60694 and IEEE/ANSI C37.34-1994, the standards a substation or switchgear spec normally calls out for flexible connectors on high-voltage switches. If your drawing references C37.34 for jumpers on a disconnect switch, this braid is specified to it.

Each end is a 2-hole terminal pad, so it takes two bolts per end (four fasteners total for the jumper). Bolts, nuts and washers are not part of the connector, so order hardware separately and match it to the bolt pattern already drilled in your bus or equipment pad.

The conductor is tin-plated copper. The tin plating is what makes it acceptable against aluminum bus as well as copper, since it keeps bare copper from sitting directly on aluminum at the joint. Clean both mating faces and use a joint compound suited to the metals you are bolting together.

No. The 17 inch figure is the length of the braid itself, and a flexible jumper needs slack rather than tension, so it will not reach a span at or near 17 inches, let alone a longer one. Measure pad face to pad face along the path the braid will actually take, allow for the loop or offset you need for movement, and order a longer braid in the same FBE 2-hole series if the span exceeds that.

Braid is the choice when the two ends move relative to each other. A rigid bar transfers thermal growth and vibration straight into the pads and the bolted joints; a flat extra flexible braid flexes in the short axis and takes that movement instead. Compared with a stranded cable jumper, the flat profile gives more surface for heat dissipation and bends more readily in one plane, which is why it is standard on disconnect switches and switchgear bus. If the connection never moves and the run is straight, a solid bar or a bolted bus link is the simpler part.

Country of origin is the United States, which is what a government, utility, or federally funded job typically needs on record for domestic sourcing requirements.

Sold each, one braid per unit. A jumper set that needs three phases means three pieces, so order quantity by the number of connections, not by phase group.
