Blackburn SWB070A1609INS FLEX BRAID TNCU 700A 2H 50.8X609MM

It's a flat, flexible tin-plated copper braid connector with two bolt holes at each end, used to carry high current between rigid bus bars or equipment terminals while allowing movement, thermal expansion, and vibration isolation. Common places you'll see it: switchgear bus joints, transformer terminal connections, generator and UPS bus links, and grounding bonds across expansion joints. Because the conductor is flexible braid rather than solid bar, it absorbs misalignment that a rigid bus link would transfer straight into the equipment terminal.

The braid is 609 mm, which is 24 inches, and the designation calls out 50.8 mm across, so it's a 2-inch wide flat braid. Measure the span between your two bolt landings before ordering, and remember a flex braid should be installed with a little slack so it can actually move; if your terminals sit 24 inches apart dead on, you want the next length up, not this one.

700 amps. The 700A figure is part of the part identity, so if your bus section runs above that you need a heavier braid or a second braid in parallel rather than this one.

Three things. Bolt hole pattern at each pad, since this is a two-hole termination and your bus drilling has to match the pad spacing. Span between landings, against the 609 mm (24 in) braid length, with slack allowed. And current, against the 700A rating. Width matters too: at 50.8 mm the pads want a bus face at least that wide to seat flat.

The conductor on the SWB070A1609INS is tin-plated copper. The tin plating slows oxidation at the bolted pads, which is what keeps joint resistance from creeping up over time, and it's the usual call for damp, industrial, or outdoor-rated enclosures and for bolting to plated or aluminum bus. Bare copper is fine in clean dry gear but needs joint compound and more attention at inspection.

Use rigid bar when both landings are fixed, aligned, and nothing moves. Go to a flexible braid like this 2-hole tin-plated copper unit when there's relative motion to absorb: rotating or reciprocating equipment, generator and transformer terminals that vibrate, long bus runs with thermal growth, or two pieces of gear set on separate structures. A rigid link in those spots loads the terminal and eventually cracks a pad or loosens the bolts.

No hardware is included. The braid is sold as one piece, each, so plan on supplying your own bolts, flat and Belleville washers, and nuts sized to your bus hole pattern, plus any insulating boot or sleeve your spec calls for. Torque to the equipment manufacturer's value for the pad, not the bolt's generic rating.

Yes, within reason. A flat flexible braid tolerates offset, twist, and angular misalignment between the two pads, which is the main reason to choose braid over solid bar. It is not a substitute for correct bus geometry though, and you should never stretch it taut to make up distance; the braid must be able to flex or you lose the benefit and put strain on the pads.

Yes, country of origin is the United States. That matters if you're buying for a federal, transit, or other domestic-preference project where the electrical bill of material has to carry US origin documentation.
