Blackburn STB150A1304 – Frequently Asked Questions
1) What is the Blackburn STB150A1304 flexible braid connector used for?
It's a flexible braided shunt connector used to carry current between two rigid points that move or need isolation from vibration and thermal expansion, typically bus bar to bus bar, switchgear connections, or transformer terminal to bus. The braid is tin-plated copper in a flat conductor shape, and it lands with a two-hole pad at each end. Rated 1500A per the model designation and built to IEEE/ANSI C37.34.
2) Does the STB150A1304 meet the switchgear connector standard our spec calls out?
It is built to IEEE/ANSI C37.34, the standard for high voltage air switches and their connectors. If your drawing calls for a C37.34 flexible connector, this Blackburn braid meets that reference.
3) Why choose a flexible braid instead of a solid copper bus link between two bus bars?
Solid bar is fine where both ends are fixed and stay fixed. A flexible braid is what you use when the two ends move relative to each other: thermal expansion along a bus run, vibration from a transformer or breaker, or a draw-out connection that needs to give. The STB150A1304 uses a flexible flat braid construction rather than a rigid conductor, so the joint absorbs that movement instead of loading the terminal pads.
4) Is the STB150A1304 braid a two-hole or single-hole termination?
Two-hole pads. That matters on high current gear, because a two-hole landing resists rotation under fault forces and gives a more stable contact area than a single bolt. Your bus bar or terminal pad needs matching two-hole drilling on both ends of the run.
5) Is the braid bare copper or plated, and will it hold up in a damp or outdoor enclosure?
The conductor is tin-plated copper, not bare. The tin plating slows oxidation on the strands and at the contact faces, which is why plated braid is the usual pick for outdoor switchgear, substation, and unconditioned enclosure work where bare copper would tarnish and raise joint resistance.
6) Do the mounting bolts come with the STB150A1304 braid connector?
No hardware is part of the connector itself. The braid ships as the conductor with its two-hole pads, so plan on supplying bolts, flat washers, Belleville washers, and nuts sized to your bus drilling, plus joint compound if your spec calls for it.
7) What part number should I give my distributor for this 1500A 304mm flexible braid?
Order Blackburn STB150A1304. That single number covers the 1500A, two-hole, 304 mm tin-plated copper flexible braid, and it is the manufacturer part number as well as the model designation.
8) Is the Blackburn STB150A1304 sold individually or in a pack?
Sold each. One braid connector per unit, so order one per connection point, not per pair of terminals.
9) Is the Blackburn STB150A1304 made in the USA for a Buy American job?
Country of origin is the United States. That's the data point procurement usually needs for domestic sourcing paperwork on public and utility work.
