Blackburn SWD210A1457T SWG XFORM LINK TNCU 2100A 4H 457MM

It's a flexible braid connector (transformer/switchgear link) built from tin-plated copper in a flat braid form, used to make a flexible current-carrying connection between bus, transformer terminals and switchgear pads where rigid bus can't absorb movement or misalignment. It's sold each, with a 4-hole pad pattern at the terminations and a 457 mm length.

The SWD210A1457T is a 2100 A link, per the 210A designation in the Blackburn part number. Match that against the continuous rating of the switchgear or transformer bus you're tying into; use a higher-rated link if your bus exceeds 2100 A.

The terminations on this link are 4-hole pads, which is the common NEMA-style drilling on medium-voltage switchgear and transformer bushing pads. Before ordering, confirm your pad drilling is 4-hole and that the hole spacing matches; a 2-hole or single-hole pad needs a different termination configuration in the series.

Yes. The SWD210A1457T is built to IEEE / ANSI C37 and 34, the switchgear and high-voltage apparatus standards, which is what a utility or institutional spec normally calls for on transformer and switchgear links.

The tin plating on this braid slows oxidation at the bolted pad interface, which keeps contact resistance and joint temperature rise stable over time. It also makes the link safer to bolt to aluminum or tin-plated switchgear pads than bare copper would be. The conductor underneath is copper, so ampacity is copper ampacity.

Use the flexible braid where the connection has to move: thermal expansion of a bus run, transformer vibration, seismic movement, or pad-to-pad misalignment during install. Rigid bar transmits that stress straight into the bushing or pad. The SWD210A1457T is a flat flexible braid, so it accommodates that movement while keeping a 2100 A bolted connection.

Order Blackburn SWD210A1457T. The number breaks down as the SWD switchgear link series, 210A for the 2100 A rating, 457 for the 457 mm length, and T for the tin-plated copper conductor. Length, rating and hole count are all fixed in that number, so there is nothing further to specify.

Country of origin is the United States, and it's sold as a single unit, each. That matters on public and institutional work where domestic-origin documentation is part of the submittal.
