Blackburn SWD210A1661 – Frequently Asked Questions
1) What is the Blackburn SWD210A1661 actually used for?
It's a flexible braid connector, or switchgear transformer link, used to make a current-carrying connection between two bus or terminal pads where some movement, thermal expansion, or vibration has to be absorbed. The conductor is tin-plated copper braid in a flat shape, rated 2100A, with a four-hole pad on each end for bolted terminations. It is built to IEEE/ANSI C37.34.
2) Is a 2100A braid link the right size for my switchgear bus?
The SWD210A1661 is rated 2100A continuous, so it suits bus runs and transformer connections at or below that rating. If your bus is rated higher, use a larger link or run links in parallel per the gear manufacturer's arrangement. It is a single-rating part, sold each, so a three-phase set needs three.
3) Why tin-plated copper instead of bare copper braid?
The tin plating on this braid protects the copper from oxidation and corrosion at the bolted pads, which keeps contact resistance stable over time. It also mates well with both aluminum and copper bus pads, and it's the standard finish for switchgear and outdoor or damp-location work.
4) What bolt pattern does the SWD210A1661 have on its terminals?
Each end is a four-hole pad, the standard NEMA-style bolted arrangement used on switchgear and transformer bushings. Confirm the hole spacing on your existing pads matches before you plan the connection, since a four-hole pad only lands on a four-hole drilling.
5) Does this braid link meet switchgear specifications for a utility or institutional job?
It is built to IEEE/ANSI C37.34, the standard covering test code for high-voltage air switches, and it is made in the United States. Those two facts cover most switchgear submittal and domestic-content questions on utility, government, and campus work.
6) Can a flexible braid link replace a solid bus bar between a transformer and switchgear?
That's exactly the job it's for. Solid bar transmits every bit of thermal growth and vibration into the bushing, while a flat flexible braid absorbs the movement and misalignment between the transformer throat and the gear. Pick the braid where the two pads move relative to each other or don't line up perfectly; stay with solid bar where the run is rigid and fixed.
7) How do I order the Blackburn SWD210A1661, and is hardware included?
Order by the manufacturer part number SWD210A1661, sold as each. It's a single configuration, 2100A at 661 mm with four-hole pads, so there is nothing to specify beyond quantity. Plan on supplying your own bolts, Belleville washers, and joint compound to suit your pad thickness and drilling.
