Blackburn EXB110A1915 EX-FLEX BRAID TNCU 1100A 2H 915MM

It's an extra flexible braid connector, a flat tin-plated copper braid used as a flexible current-carrying link between two bolted connection points, typically substation bus, switchgear, and disconnect switch terminals where thermal movement, vibration, or slight misalignment has to be absorbed. It's a 2-hole style connector, so each end bolts down on two fasteners rather than one, which keeps the pad from rotating under load. Sold individually.

Tin plating on the copper braid slows oxidation at the contact surfaces and on the strands themselves, which matters on outdoor substation and switchgear work where a bare copper braid would corrode and the joint resistance would climb. It also makes the braid friendlier to aluminum pads than bare copper would be. The conductor underneath is still copper, so current-carrying performance is copper's.

Use a flexible braid like this one wherever the two pads can move relative to each other: thermal expansion on a long bus run, vibration from a transformer or breaker, seismic movement, or an installation where the two pads aren't perfectly aligned. A rigid bar transmits all of that stress straight into the terminal and eventually cracks the pad or loosens the bolts. Where both ends are fixed to the same structure and alignment is controlled, rigid bar is simpler. This part is the flexible flat braid answer, 915 mm long with 2-hole pads at each end.

Two-hole pads on each end. It matters on high-current work: a two-bolt pattern locks the pad against rotation and spreads clamping force across a larger contact area, which is why utility and substation specs generally call for two-hole terminations on large conductors. If your existing pad is drilled for a single bolt, this won't land on it without redrilling the pad.

Order by manufacturer part number EXB110A1915 from Blackburn. It ships as a single braid assembly, priced and sold each, not by the pair, so a connection needing two links takes a quantity of two. It's made in the United States.

The EXB110A1915 is the braid assembly itself, with the two-hole pads formed on each end. Bolts, nuts, flat and Belleville washers for landing it on your pads are separate, and the sizes depend on the drilling of the terminals you're bolting to, so those need to be specified with the rest of the connection hardware.
