Blackburn SWD210A3762 FLEXIBLE BRAIDS, 30 INCHES

The SWD210A3762 braid is 30 inches (762 mm) long. That length is fixed, so when you are sizing a substation or switchgear jumper, measure the pad-to-pad run plus the slack you need for thermal movement and equipment travel before settling on this one.

It is built to IEEE/ANSI C37.34, the standard covering high-voltage air switches and their flexible connectors. That is the reference a utility or institutional spec writer usually calls out for braid jumpers on disconnect switches and bus work.

It is a 4-hole standard flexible braid connector, so each flat terminal pad bolts through four holes. Match the drilling on your bus or switch terminal pad before ordering, because a 4-hole pad pattern will not land on a 2-hole prep without an adapter plate.

The conductor is tin-plated copper. The tin plating is there to resist oxidation on the braid strands and at the bolted pad interface, which is why this style is used on outdoor switchgear and substation connections rather than bare copper braid.

Use a braid where the two ends move relative to each other: expansion joints in bus runs, disconnect switch blades, transformer terminal to bus, or anywhere vibration would fatigue a solid link. The SWD210A3762 is a flat, flexible conductor built for exactly that duty. If both landing points are fixed and rigid, a solid bus link or a bolted bus bar is the simpler connection.

The braid itself is what ships, one per unit. Plan on supplying the bolts, nuts, washers and any Belleville hardware sized to your terminal pad drilling, since the four holes at each end have to match what you are bolting to.

It sells each, one braid per unit. Most jumper applications need one braid per phase, so a three-phase switch replacement means three units.

Country of origin is the United States, which matters if your project carries a domestic sourcing requirement such as a federal or utility Buy American clause.
