Blackburn SWD210A1635 SWG XFORM LINK TNCU 2100A 4H 635MM

It's a flexible braid switchgear transformer link, rated 2100A, used to connect transformer terminals to switchgear bus or other rigid bus work where some movement, thermal expansion, or misalignment has to be absorbed. The conductor is flat, flexible, tin-plated copper, and it lands with a 4-hole pattern on each end.

Yes, 2100A is the rating on the SWD210A1635 switchgear transformer link. Match it against the continuous current of the bus run it's bridging, not just the transformer nameplate.

Four per terminal pad. Confirm your transformer throat and switchgear bus are drilled for a 4-hole NEMA pattern before you order; a 2-hole pad won't line up and you'd be drilling field holes in a current-carrying joint.

The tin plating on the SWD210A1635 braid resists oxidation at the bolted joint, which keeps contact resistance and joint temperature down over time. It also lets the braid land against aluminum or tin-plated bus without the galvanic problem bare copper creates.

It's sold each. For a three-phase connection you order three, one per phase, plus any neutral link separately.

Country of origin is the United States, which matters on federally funded and utility work carrying domestic content requirements.

Only if nothing moves. Rigid bar transmits vibration and thermal expansion straight into the transformer bushings and the switchgear bus supports. The SWD210A1635 is a flexible flat braid specifically so the joint can take that movement and any small misalignment between the transformer pad and the gear. If the connection spans two separately mounted pieces of equipment, use the flexible link.

Blackburn SWD210A1635. The number breaks down as the switchgear braid link family, 2100A rating, and 635 mm length, so adjacent Blackburn SWD part numbers differ in ampacity and length.
