Blackburn EXB110A12135 EX-FLEX BRAID TNCU 1100A 2H 2135MM

It is an extra flexible braid connector with two-hole terminal pads at each end, used as a flexible current-carrying jumper between rigid bus, switchgear, or disconnect terminals where the connection has to absorb movement, thermal expansion, or vibration. The braid is tin-plated copper and the conductor is flat, so it flexes in one plane rather than twisting like a round cable. It is rated 1100A and built to IEEE/ANSI C37.34.

1100A is the rating carried by this braid connector, and it is built to IEEE/ANSI C37.34, the standard for high voltage air switches and their connectors. Match the rating to the bus or switch it lands on, and keep both two-hole pads fully bolted to the mating pad so the full cross section is in the circuit.

Each end of the EXB110A12135 is a two-hole terminal pad, so it lands on a bus or switch pad drilled for two bolts. Before ordering, confirm the hole diameter and the hole spacing on your existing pad match the braid's pads; a two-hole pad is not universal, and a single-hole terminal will need a different braid. Hardware is not part of the braid itself.

The conductor here is tin-plated copper. The tin plating slows oxidation on the braid and on the pad faces, which keeps contact resistance stable over time and makes it a better match when you are bolting to aluminum or plated bus rather than bare copper. Electrically you still get a copper conductor.

Use the braid where the two terminals move relative to each other, from switch operation, thermal growth of a long bus run, or vibration in the structure. A rigid link transmits that movement straight into the terminal and eventually cracks a pad or loosens the bolts. This is a flexible, flat-conductor braid, so it takes the movement in the loop. If both terminals are fixed and close together, a rigid bus link or a short flexible connector is simpler.

Order Blackburn EXB110A12135. That is the manufacturer part number for the 1100A tin-plated copper extra flexible braid with two-hole pads at 2135 mm length. The EXB prefix is the extra flexible braid line; the trailing digits carry the ampacity and the length, so a different length or amp rating is a different number entirely.

It is sold each, one complete braid assembly with a two-hole pad at both ends, so order one per connection point. Country of origin is the United States, which matters if you are working a job with domestic-content requirements.
