Blackburn SWC215A1605 BOREAL FLEX BRAID XUL467818A9532

It's a flat flexible braid connector used to make a bonding or grounding connection between two bolted terminals that need to move relative to each other, such as switchgear, disconnect blades, transformer bushings, and bus bar joints. The braid is tin-plated copper, and the connector is built to the IEEE / ANSI C37, 34 standards for switchgear connections.

It is a 4-hole configuration, so each termination pad bolts through four holes rather than one or two. Your existing pad or bus drilling has to match a 4-hole pattern; a single-hole or 2-hole pad needs a different braid.

The tin plating on this Blackburn braid slows oxidation at the surface and on the bolted pads, which matters in outdoor, damp, or industrial switchgear enclosures where a bare copper braid would dull and build resistance at the joint. It also makes the braid friendlier against aluminum bus. Electrically you still get copper conductivity.

Use flexible braid wherever the two connection points move, vibrate, or thermally expand relative to each other, such as switch blades, breaker trucks, and transformer bushing connections. A rigid strap will work-harden and crack in those spots. This SWC215A1605 is a flexible flat braid, which is the shape that gives you bend without fatiguing the conductor.

The SWC215A1605 is built to IEEE / ANSI C37, 34, the switchgear standard, so it lines up with specs written around high-voltage air switch and switchgear connections. If your drawing calls out a different standard, verify against the sheet before substituting.

Each, one braid per unit. For a three-phase switch you would order three, and add spares if you are keeping a substation MRO shelf stocked. The manufacturer part number to specify is SWC215A1605.

Country of origin is the United States, which is what a government, utility, or federally funded project buyer needs when domestic-origin sourcing is written into the purchase order.
