Blackburn EXB110A11220 – Frequently Asked Questions
1) What is the Blackburn EXB110A11220 flexible braid connector used for?
It is a flat, extra-flexible tin-plated copper braid connector rated 1100A, with a two-hole pad at each end, used to make a flexible current-carrying connection between rigid bus, switchgear terminals, or disconnect blades where movement, thermal expansion, or vibration has to be absorbed. The braid construction lets the joint flex without stressing the bus. It is built to IEEE/ANSI C37.34 and sold each.
2) Is this braid connector rated to a recognized switchgear standard?
Yes. The Blackburn EX-FLEX braid is built to IEEE/ANSI C37.34, the standard covering high-voltage air switches and their connectors. That is the reference most utility and substation specs cite, so it satisfies a submittal calling out C37.34 flexible connectors.
3) What is the ampacity of this Blackburn EX-FLEX braid?
1100 amps. Confirm that against the continuous current of the switch or bus run it is bridging, not just the breaker frame size. If the run carries more, step up to a higher-rated EX-FLEX braid rather than paralleling two of these.
4) Does the EXB110A11220 braid come with bolts or hardware for the two-hole pads?
No. The EXB110A11220 is supplied as the braid assembly only, sold as one each. Bolts, nuts, Belleville washers, and any required bus hardware are separate and need to be sized to the hole pattern and torque your switchgear or bus spec calls for.
5) Why tin-plated copper instead of bare copper on a flexible bus braid?
The braid on the EXB110A11220 is tin-plated copper. The tin plating slows oxidation on the conductor and at the bolted pad faces, which keeps contact resistance stable over time in outdoor or humid substation and switchgear environments. It also mates cleanly with tin-plated or aluminum bus without the galvanic concerns of a bare copper-to-aluminum joint.
6) Can I use a rigid bus link instead of a flexible braid connector?
Only where nothing moves. A rigid link transmits thermal growth and vibration straight into the bus and the switch terminals. A flat flexible braid like the EXB110A11220 is what you use across expansion joints, between a switch blade and fixed bus, or anywhere a transformer or breaker moves relative to the bus. The flat shape also keeps the profile low in tight cubicles compared with round flexible cable.
7) Is the EXB110A11220 made in the USA for a Buy American job?
Country of origin is the United States. For federally funded or Buy American Act work, that is the point to document on the submittal along with the part number EXB110A11220.
