Blackburn EXB110A1610 EX-FLEX BRAID TNCU 1100A 2H 610MM

It's a flexible braid expansion connector for high-current bus and substation work, rated 1100 amps with a two-hole pad at each end. The conductor is a flat braid of tin-plated copper, classed as very flexible, so it absorbs bus expansion, contraction, and vibration between rigid conductors instead of transmitting that movement into the bus or equipment terminals.

No. The EXB110A1610 is a 1100 amp connector, so it should not be applied where continuous current exceeds that rating. Going over it puts the braid and the bolted joints above their design temperature rise. For higher loads you need a larger braid rating or parallel connections sized to the bus.

Both terminal pads are two-hole. The two-bolt pattern resists rotation under fault current and is what most bus and switch pads are drilled for, but your existing pads have to match the hole spacing and bolt size on the pad. If your bus is drilled single-hole, a two-hole braid is the wrong part for that connection.

It ships as a single complete assembly, sold each: flat tin-plated copper braid with the two-hole terminal pads already attached at both ends. No crimping or pad attachment is needed in the field, just the bolting hardware for your pads, which is not part of the assembly. Made in the United States.

For an expansion or vibration joint between rigid bus sections, a flat braid like the EXB110A1610 flexes in the plane of the bus with very little force and presents a lot of surface for heat dissipation, which is why it's the usual choice on air switches and disconnects. A round stranded cable jumper takes up more bending radius and is generally used where you need length and routing freedom rather than repeated low-force movement. This one is classed very flexible, so it is intended for the moving joint, not as a long feeder run.

Tin plating on the copper braid resists oxidation at the bolted pad faces, which keeps contact resistance from creeping up over time on an outdoor or humid substation installation. It also mates with aluminum and tin-plated bus pads without the galvanic issue you get from bare copper against aluminum.
