Blackburn SWC215A11145 FLEXIBLE BRAIDS, 45IN LENGTH

It's a flexible flat braid connector used to carry current between two rigid points that move or need isolation from vibration, such as switchgear buses, disconnect blades, transformer pads and grounding connections. The conductor is tin-plated copper in a flat flexible braid, and it's built to IEEE/ANSI C37.34, the standard for high-voltage air switches. Terminals are drilled 4-hole.

The cataloged cable length is 45 inches. Braid length is what determines how much bus movement or offset you can absorb, so lay out your two connection points before ordering, a braid that's too short pulls on the pads and one that's too long can swing into adjacent phases.

The terminals on this braid are drilled 4-hole, so they land on a four-bolt pad pattern. Match your existing pad drilling and bolt circle before ordering, a two-hole pad will not take a 4-hole terminal without an adapter pad. If your switch or bus pad is two-hole, you need the 2-hole braid version instead.

It's built to IEEE/ANSI C37.34, which covers test code for high-voltage air switches. If your drawing calls for C37.34 flexible connectors on a disconnect or air break switch, this braid is on standard.

The conductor here is tin-plated copper. Tin plating slows oxidation on the braid strands and on the terminal faces, which matters in outdoor switchyards and damp or corrosive plants where a bare copper joint builds resistance and runs hot. It also lets the braid land on aluminum bus with less galvanic concern than bare copper to aluminum.

Use a flexible braid wherever the two ends move relative to each other, thermal expansion on a long bus run, a disconnect blade that rotates, a transformer that vibrates, or seismic movement. A solid link transmits that motion straight into the pads and eventually cracks the joint or the porcelain. This braid is a flat flexible conductor for exactly that duty. Where both ends are rigidly fixed and never move, a solid bar or bus link is simpler.

Country of origin is the United States, which matters on government, utility and Buy American funded work. It's sold each, so one order line gets you one braid, order per connection point rather than per pair.
