Blackburn SWD160A1560 SWG XFORM LINK TNCU 1600A 4H 560MM

It's a flexible braid switchgear transformer link, rated 1600A, used to make the flexible connection between a transformer terminal and switchgear or bus. The conductor is tin-plated copper in a flat, flexible braid form, which lets it absorb vibration, thermal movement, and small misalignment that a rigid bar would transmit. Four-hole pads on the ends bolt to drilled terminal pads.

It's built to IEEE/ANSI C37.34, the standard covering design tests for high-voltage air switches and their connections. If your drawing calls out C37.34 for transformer-to-switchgear links, this braid satisfies that reference.

Each terminal pad is 4-hole. Your transformer and switchgear pads need a matching 4-hole drilling pattern for the braid to land flat on both ends. If your existing pads are 2-hole, this link won't bolt up without an adapter pad.

A rigid bar transfers transformer vibration and thermal expansion straight into the switchgear terminal, and it needs the two pads to line up almost exactly. A flat flexible braid like the SWD160A1560 takes that movement itself and tolerates pad offset, so it's the usual choice for the transformer-to-gear connection. Solid bar still makes sense for fixed runs inside a single enclosure where nothing moves.

The conductor is tin-plated copper. Tin plating slows oxidation at the bolted pad interface, which keeps contact resistance from creeping up over years of load cycling, and it is what lets copper terminate safely against aluminum hardware. Bare copper braid works but needs more attention to joint compound and periodic torque checks.

It's sold each. A three-phase connection needs three of them, so order by the phase count plus any spares, not by the assembly.

Blackburn SWD160A1560. That single part number covers the 1600A rating, the 4-hole pad drilling, the 560 mm length, and the tin-plated copper flexible braid, so there are no suffixes to add when ordering.

Country of origin is the United States. For federally funded work with domestic-content requirements, that matters, though the exact clause on your contract determines what documentation the specifying engineer wants on file.
