Blackburn SWA070A1346 FLEX BRAID FOR COPPER

It's a flexible braided copper connector used as a bonding or grounding jumper between two points that move, vibrate, or expand relative to each other, such as switchgear bus to a fixed conductor. The braid is tin-plated copper in a flat conductor shape, so it flexes without fatiguing a solid conductor, and the tinning helps resist corrosion at the termination. It's a one-hole style connector, meaning each end lands on a single bolt.

One-hole. Each terminal pad takes a single bolt, so you only need one drilled or tapped landing per end. If your bus or pad is prepped for NEMA two-hole spacing, this braid won't match that pattern and you should specify a two-hole braid instead. One-hole terminations also allow rotation on the bolt, which can matter if you need the braid to sit at an angle.

A flat braid and a round flexible cable do different jobs. The flat braid gives more surface area and a much lower profile, so it fits tight clearances between bus bars and takes repeated flexing better than a stranded cable that has to bend in one plane. Use round flexible cable where the run is long and unsupported; use this flat tin-plated copper braid where the two points move slightly and you're bridging a short gap, here 346 mm.

The braid is tin-plated copper, and the tin plating is what makes a copper conductor acceptable against aluminum hardware, since it keeps bare copper off the aluminum surface. Standard practice is still to use an appropriate joint compound and the hardware the bus manufacturer calls for. For an all-copper bus, tin plating simply adds corrosion resistance in damp or industrial environments.

Sold each, so one braid per order line. Bonding jumpers are normally needed in matched pairs or sets across a lineup of gear, so count the connections on the drawing and order the quantity you need rather than assuming a multi-pack.

United States. That matters on public work and federal jobs where Buy American or domestic-preference language sits in the specification, so this one can be submitted against those requirements.
