Blackburn SWC215A1457 – Frequently Asked Questions
1) What is the Blackburn SWC215A1457 flexible braid connector used for?
It's a flexible flat braid connector used to make a current-carrying connection between two rigid conductors (bus bar to bus bar, bus to equipment pad) where movement, vibration, or thermal expansion has to be absorbed. The braid is tin-plated copper, flat in shape, and it's built to IEEE / ANSI C37, 34. Sold each.
2) Is the SWC215A1457 braid a 2-hole or 4-hole pad connector?
Four-hole. Each terminal pad is drilled 4-hole, so it lands on a NEMA four-hole bus pattern rather than a two-hole pad. If your equipment pad is 2-hole drilled, this is the wrong pad configuration and you want the 2-hole version of the braid instead.
3) Why tin-plated copper instead of bare copper braid?
The tin plating on this Blackburn braid protects the copper strands from oxidation and is what you want for outdoor switchgear, substation, and damp or corrosive environments, and when landing on aluminum or plated hardware. Bare copper is fine indoors and dry but dulls and corrodes faster at the joint.
4) What standard does this Blackburn flexible braid meet?
The SWC215A1457 is built to IEEE / ANSI C37, 34, the standard family covering high-voltage air switches and their connection hardware. That's the reference to quote on a substation or switchgear submittal.
5) Can I use a flexible braid instead of a solid bus link between switchgear sections?
Use the braid wherever the two ends can move relative to each other: transformer to bus, disconnect switch blades, expansion joints, seismic breaks, or anywhere thermal growth would otherwise load the bolted joint. A rigid bus link is fine only when both ends are fixed and aligned. This connector is the flexible flat-braid type, so it takes that movement without stressing the pads.
6) Does the SWC215A1457 braid come with mounting bolts?
No hardware is included. The braid is supplied as a single piece, each, with the four-hole pads drilled and ready. Bolts, flat and Belleville washers, nuts, and joint compound are ordered separately to suit your pad thickness and bolt size.
7) Is the Blackburn SWC215A1457 made in the USA?
Country of origin is the United States, which matters if you're buying against a Buy American or domestic-preference clause on a utility or government job.
