Blackburn EXB110A11524 EX-FLEX BRAID TNCU 1100A 2H 1524MM

It is an extra flexible braid connector, a flat tin-plated copper braid with a two-hole pad on each end, used to carry current across a joint that has to move or take vibration, expansion, and misalignment (switchgear, disconnects, bus connections, transformer terminations). The braid construction lets the two terminations shift relative to each other without stressing the pads, which a rigid bar cannot do. It is built to IEEE/ANSI C37.34 and sold each.

The EXB110A11524 is the 1100 amp member of Blackburn's EX-FLEX braid line, so it is sized for a connection point carrying up to 1100 A. Rated capacity on this family follows IEEE/ANSI C37.34, the standard for high voltage air switches, which is where the braid's current rating and test basis come from. If your bus or switch is rated above 1100 A, step up to a higher-ampacity braid rather than paralleling this one.

The conductor is tin-plated copper. Tin plating is what lets a copper braid land on an aluminum bus bar or pad without the bare copper-to-aluminum contact that drives galvanic corrosion, and it also slows oxidation on the contact face of the pads. Still clean the mating surfaces and use the joint compound and torque your switchgear manufacturer specifies.

Use a braid where the two ends move relative to each other. Anything with thermal expansion, equipment vibration, a hinged or rotating switch blade, or terminations that are slightly out of plane needs the flexible flat braid, which absorbs that movement instead of transmitting it into the bolted pads. A solid link is the right choice only for a fixed, well-aligned, rigid joint. The EX-FLEX braid is classed as a flexible conductor with a flat shape, which is what gives it the bend without losing contact area at the pads.

Two bolt holes per terminal pad keep the braid from rotating under fault current or vibration and spread the clamping force over more of the contact face, which is what you want at 1100 A. It does mean the receiving bus or switch pad has to have a matching two-hole drilling on the same centers, so confirm the existing pad pattern before ordering, since a single-hole pad cannot take this connector without adapting.

Blackburn EXB110A11524. That single manufacturer part number covers the tin-plated copper flexible braid at 1100 A with two-hole terminations and a 1524 mm length, and it is the only configuration that number describes, so there is no length or plating option to specify separately.

Country of origin on the EXB110A11524 is the United States, which is the line institutional and utility buyers need for domestic-preference documentation. It ships as a single piece, sold by each, so one part number covers one braid assembly on your purchase order.
