Blackburn FBE1H035A1-12 XFLEX BRAID 9/16H 3/16X1.5 X 12 IN

12 inches overall. That length is fixed on this part number, so if your span between pads is longer or shorter you need a different length in the FBE1H family rather than stretching or folding this one. The braid section itself is flat, 3/16 by 1-1/2 inches, with 9/16 inch mounting holes.

It is built to CEI 60694 and IEEE/ANSI C37.34-1994, the standards engineers typically call out for high-voltage switchgear connectors and disconnect switches. Those two references are what you'd cite on a submittal for substation or switchgear work.

It's a tin-plated copper flexible braid connector with a single bolt hole at each end, used to make a current-carrying connection between two points that move or vibrate relative to each other, or where thermal expansion would stress a rigid bus. Typical uses are switchgear bus jumpers, transformer and breaker connections, and bonding jumpers across expansion joints. The braid construction lets the connection flex without fatiguing a solid conductor.

Tin-plated copper. The plating is what lets it land on aluminum or tin-plated bus without the galvanic corrosion you'd get from bare copper against aluminum, and it holds up better in damp or industrial atmospheres than bare braid.

That's exactly the case for it. A rigid bus link transmits vibration and thermal movement straight into the bolted joint and eventually loosens it or cracks the conductor. The flexible flat braid absorbs that movement while still carrying current, which is why it's the standard choice between a transformer bushing and bus, across expansion joints, or at a moving disconnect blade. Where nothing moves, a solid bar or a compression connector is simpler.

FBE1H035A1-12 is the Blackburn catalog number. The trailing -12 is the 12 inch length, so the same family carries other lengths under different suffixes.

Country of origin is the United States, which matters if you're buying under a domestic-preference or Buy American clause on a government or utility job.
