Blackburn SWD210A1508 SWG XFORM LINK TNCU 2100A 4H 508MM

It's a flexible braid switchgear transformer link, rated 2100A, used to make a flexible current-carrying connection between bus or transformer pads and switchgear where rigid bar can't absorb movement, thermal expansion, or slight misalignment. The conductor is flat, flexible, tin-plated copper, and it's built to IEEE / ANSI C37, 34. Sold each.

It's a 4-hole configuration, which matches the standard NEMA four-bolt pad drilling used on large switchgear and transformer terminal pads. Confirm your pad hole spacing matches before you order, since a four-hole pad and a two-hole pad are not interchangeable without an adapter.

The link is built to IEEE / ANSI C37, 34, the switchgear standard referenced on most utility and industrial switchgear submittals. It's also made in the United States, which covers Buy American language on federal, municipal, and institutional projects.

Tin plating on the copper braid slows oxidation at the bolted interface and lets the link land on aluminum or plated-aluminum pads without the galvanic problems a bare copper face can create. For switchgear and transformer terminations that get torqued once and left for decades, that matters more than raw conductivity.

Only if nothing moves. Rigid bar is fine for fixed bus runs, but a flexible braid link is what you use where the connection has to tolerate thermal growth, vibration from the transformer, or pad misalignment during assembly. This one is specifically a flexible, flat-conductor link, so it's the right choice where a bar would transmit stress into the bushing or pad.

Rated 2100A. Paralleling links to make up a higher ampacity is a design decision that depends on your bus arrangement and pad space, so size it off the switchgear drawings rather than assuming two links double the rating. If 2100A doesn't cover the bus, specify a higher-rated link in the same flexible braid family instead.

The SWD210A1508 is sold as a single link, each. Bolting hardware for the pad connection is ordered separately, so plan on the correct grade bolts, flat washers, and Belleville washers sized to your pad hole diameter to hold torque through heat cycling.
