Blackburn SWF230A1915 SWG XFORM LK TNCU 2300A 6H-4H 915MM

It is a flexible flat braid connector for switchgear and transformer connections, rated 2300A, with a 6-hole pad on one end and a 4-hole pad on the other. The conductor is tin-plated copper braid, which lets it absorb thermal expansion, vibration and slight misalignment between rigid bus bars or between a transformer bushing pad and switchgear bus. Overall length is 915 mm.

One end is drilled 6-hole, the other 4-hole, so it is made to land on standard NEMA-style drilled bus and transformer pads with matching hole patterns. Match the hole pattern on each end of your run to the correct end of the braid before you order, because the two ends are not interchangeable.

2300A. Size the connection to the continuous current of the bus it is bridging; at 2300A this is a main-bus or large transformer secondary part, not a tap or ground braid.

It is built to IEEE/ANSI C37.34, the standard covering design tests for high-voltage air switches and their connectors. If your submittal package calls for C37.34 on flexible connections, this part answers it.

The braid is tin-plated copper. Tin plating slows oxidation at the bolted interface, which keeps contact resistance stable over time, and it is the right match when the mating pad is aluminum or tin-plated bus. Bare copper against those surfaces is where you get galvanic and oxide problems at the joint.

That is exactly what it is for. Where a rigid bus bar transmits thermal growth and vibration straight into the bushing or the gear, a flat flexible braid lets the two ends move relative to each other while still carrying full current, here 2300A. Use a rigid link only where both pads are fixed and aligned; use the braid where there is expansion, seismic movement, or an alignment offset to absorb.

Sold each. A three-phase connection needs three, so order per phase plus any spares your MRO stock calls for. It is manufactured in the United States.
