Blackburn FBE2H090A1-18 XFLEX BRAID 2 9/16H 11/32X1.5X18 IN

Reading the Blackburn shorthand: 2 9/16H is the two 9/16 inch bolt holes in the terminal pads, and 11/32 x 1.5 x 18 gives the braid section and length, 11/32 inch thick by 1-1/2 inch wide by 18 inches long. So you need 1/2 inch hardware through 9/16 inch holes, and a landing pad at least 1-1/2 inches wide to match the braid and pad width.

It's a flat, extra-flexible tin-plated copper braid connector with two bolt holes on each pad, used to make a current-carrying connection between two rigid points that move relative to each other, such as switchgear buses, disconnect blades, transformer terminals, and expansion or vibration joints. The flat braid construction lets the joint flex and absorb thermal movement without stressing the bolted pads. Overall cable length is 18 inches.

It is built to CEI 60694 and IEEE/ANSI C37.34-1994, the high-voltage switchgear and air disconnect switch standards. That's the reference a utility or substation spec writer is usually looking for on a flexible shunt, and it is why this braid shows up on disconnect switch and switchgear submittals.

The conductor is tin-plated copper. Tin plating slows oxidation on the braid and the bolted faces, which matters in outdoor and damp substation environments. On aluminum bus you still want the bimetallic practice you would use on any copper-to-aluminum joint: a tin-plated or bimetallic interface plus the correct joint compound, since tinning the copper alone does not eliminate the dissimilar-metal concern.

Use flat braid like this 11/32 x 1-1/2 inch, 18 inch Blackburn part where the connection has to flex repeatedly or absorb thermal expansion in a confined space: flat braid bends easily in one plane and keeps a low profile between closely spaced buses. A round stranded cable jumper with lugs is the choice when the run is longer, the routing needs to bend in more than one direction, or the termination is a stud rather than a flat drilled pad.

Country of origin on the FBE2H090A1-18 is the United States, which is what a government, utility, or federally funded project needs to see on the submittal for domestic-content review.
