Blackburn SWA070A1304 – Frequently Asked Questions
1) What is the Blackburn SWA070A1304 flexible braid connector used for?
It is a flexible tin-plated copper braid connector used to make a current-carrying connection between two rigid points, typically bus bars, switchgear connections, or disconnect terminations, where some movement, vibration, or thermal expansion has to be absorbed. The braid is flat and flexible rather than solid bar, so it flexes without loading the terminations. It is rated 700A and built to IEEE/ANSI C37.34.
2) Will a tin-plated copper braid work on aluminum bus bar?
Tin plating on the copper braid is what makes the dissimilar-metal connection practical. Bare copper against aluminum galvanically corrodes; the tin plate puts a compatible surface between the two. Use an inhibiting compound rated for the joint and the correct Belleville and torque for the bolt size, as you would with any aluminum bus termination.
3) Does this 700A braid meet the switchgear standard my spec calls out?
The SWA070A1304 is built to IEEE/ANSI C37.34, the standard covering high-voltage air switches and their connectors, which is the reference most switchgear and substation drawings cite for flexible braid shunts. It carries 700A.
4) Should I use a flexible braid or a solid copper bus link between two bus bars?
Use the braid wherever the two points move relative to each other: expansion joints on long bus runs, connections to a switch blade or operating mechanism, equipment on vibration isolators, or anywhere thermal cycling would otherwise transmit stress into the pads. A solid link is fine only where both ends are rigidly fixed and stay fixed. This one is a flat flexible braid, which takes bending across the flat face while keeping a large surface area for current.
5) Is the SWA070A1304 sold individually or in pairs?
Sold each. One order quantity gets one braid, so if you are shunting three phases order three. It is manufactured in the United States, which matters on jobs with domestic content requirements.
6) What is the Blackburn part number for a 700A one-hole flexible braid at 304 mm?
SWA070A1304. That designation breaks down as the Blackburn SWA flexible braid family, 700A, one-hole pads, 304 mm length, in tin-plated copper.
