Blackburn SWA070A1610 FLEXIBLE BRAID 610MM LENGTH

It is a flexible braid shunt connector, used to carry current across a joint that has to move or flex, such as the connection between a switch blade and a stationary terminal, or a bonding jumper between two pieces of equipment that shift with load, thermal growth, or vibration. The conductor is a flat flexible braid rather than solid bar or stranded cable, so it bends without work-hardening the connection point. The terminal end is a 1-hole pad, so it bolts to a single drilled terminal or pad.

The braid is built to IEEE/ANSI C37.34, the standard covering test code for high-voltage air switches and their current-carrying connections. If your drawing calls for a shunt or braid conforming to C37.34, this one answers that line item. It is also made in the United States, which matters on jobs carrying domestic-content requirements.

The conductor is tin-plated copper. The tin plating is what makes it suitable for exposed switchgear and outdoor pad connections: it slows the oxide film that forms on bare copper at a bolted joint and keeps contact resistance stable over time. It also lets you bolt to aluminum or tin-plated aluminum pads with less galvanic concern than bare copper against aluminum.

Use the braid where the joint moves. A flat braid flexes repeatedly in one plane with very little reaction force on the terminal, so a rotating or sliding switch blade is not fighting the conductor every operation. Flexible cable of the same ampacity is stiffer in bending and tends to fatigue at the lug throat when it is cycled. Cable is the better choice for a fixed run between two static terminals where nothing moves and you only need the conductor to route around obstructions.

It sells each, as a single braid. Bolt-for-bolt, one part covers one connection point, so if you are shunting both sides of a switch or replacing braids across a three-phase set, order the quantity you need rather than expecting a multipack. Mounting bolts and washers are not part of the conductor itself, so plan hardware to suit the pad you are landing on.

Order it as Blackburn SWA070A1610. That manufacturer part number identifies the flexible braid with the 1-hole terminal in tin-plated copper, so quoting it avoids getting a two-hole pad or a different braid width by mistake.
