Blackburn SWD160A1304 SWG XFORM LINK TNCU 1600A 4H 304MM

It's a flexible braid connector, or flexible link, used to make the current-carrying connection between switchgear and transformer bus. The conductor is tin-plated copper, flat in shape, rated 1600A, with a 4-hole pad on each end and a 304 mm length.

Yes, it's a 4-hole connector, so both terminal pads are drilled for four bolts. That matches standard 4-hole NEMA bus pad drilling on 1600A switchgear and transformer throats. If your bus pads are 2-hole, this link will not bolt up without adapters, so order a 2-hole version instead.

Rated 1600A. Size the link to the bus rating it bridges, not to the load, and use one link per phase, since it's sold each.

One. The selling unit is each, so a three-phase switchgear-to-transformer connection takes three SWD160A1304 links, plus a fourth if you're also linking neutral.

A solid bar transmits every bit of transformer vibration and thermal growth straight into the switchgear bus and the bolted joints. A flexible flat braid like this one takes up that movement and tolerates small misalignment between the two enclosures, which is why flexible links are standard practice at the transformer throat. Use solid bar only where the two pads are rigidly aligned and there is no movement to absorb.

The conductor is tin-plated copper. The plating slows oxidation at the bolted pad interface, which keeps contact resistance and running temperature down over time, and it lets the copper pad bolt to aluminum bus without the galvanic problem bare copper creates.

Country of origin is the United States, which is what government, healthcare and education specs with domestic-content language typically require documented.
