Blackburn SWD160A1610 SWG XFORM LINK TNCU 1600A 4H 610MM

It is a flexible braided link used to connect switchgear and transformer terminations where a rigid bus bar would transmit vibration or thermal movement. The braid is tin-plated copper, very flexible conductor category, in a flat shape, with a four-hole pad at each end for bolted bus connections. It is built to IEEE/ANSI C37.34.

It comes as a 4-hole connector, so the terminal pads are pre-punched for bolted connection to bus or terminal pads. No field drilling. Match your bus bolt pattern to the pad drilling before installing, since the pads are fixed and cannot be re-drilled without compromising the plating.

A solid bar carries vibration and thermal expansion straight into the terminations, which loosens bolted joints over time. The braid is a very flexible flat conductor, so it absorbs that movement and allows for a small amount of misalignment between the transformer and the switchgear bus. Use a rigid bar where the connection is short, fixed, and fully supported; use the braid where anything moves.

The conductor is tin-plated copper. Tin plating resists oxidation on the strands and at the bolted pad face, which is what you want on a switchgear joint that has to hold contact resistance over years. It also makes it suitable for bolting to either copper or aluminum bus with the appropriate joint compound and torque.

It is built to IEEE/ANSI C37.34, the standard covering high-voltage air switches and their connection hardware. That is the reference a utility or institutional spec writer will look for on a transformer-to-switchgear flexible link.

Sold each. A three-phase connection needs three, so order per phase plus any neutral or ground link the drawing calls for. It is made in the United States.

The manufacturer part number is SWD160A1610, a Blackburn switchgear transformer link. One model, one configuration: tin-plated copper flat braid, four-hole pads, 610 mm.
