Blackburn SWD210A1965 SWG XFORM LINK TNCU 2100A 4H 965MM

It's a flexible braided switchgear transformer link, rated 2100A, used to make a flexible current-carrying connection between rigid bus, transformer terminals, and switchgear where thermal movement, vibration, or slight misalignment has to be absorbed. The braid is tin-plated copper in a flat conductor shape, and it's built to IEEE/ANSI C37.34.

Four holes per pad, so it lands on a 4-hole NEMA-style drilled bus or transformer pad. If your existing pads are drilled 2-hole, this link won't bolt up directly and you need a 2-hole version instead.

2100 amps. Size the link to the continuous rating of the switch or transformer secondary it's connecting, not to the breaker frame alone, and confirm the bolted pad area matches so the joint carries the same current the braid does.

Tin plating on the copper braid gives a stable, oxidation-resistant contact surface at the bolted pads, which keeps joint resistance and running temperature down over time. It also lets you bolt to aluminum or tin-plated bus without the galvanic problems of a bare copper-to-aluminum joint.

Use the flexible braid where the connection has to move: transformer-to-switchgear terminations, expansion joints, and anywhere vibration or thermal growth would otherwise load the terminal pads. Solid bar is the better choice on fixed, aligned runs inside a rigid enclosure. The SWD210A1965 is a flexible, flat-shape conductor, so it takes that movement without transmitting stress to the bushing.

It is built to IEEE/ANSI C37.34, the standard covering test code for high-voltage air switches and their connection components. That's the reference a utility or institutional spec writer usually calls out for switchgear connectors of this class.

Sold each, one link per unit. A three-phase termination needs three, so order by phase count plus any spares your maintenance stock calls for. It's made in the United States, which matters if you're buying against a domestic-content requirement.

Blackburn SWD210A1965. The number reads out as the spec: 2100A rating, 4-hole pads, 965 mm length, tin-plated copper braid.
