Blackburn SWC215A1755 BOREAL FLEX BRAID XUL467819A9532

It's a flexible flat braid connector used to bond or jumper between two bolted terminations where the connection has to move or absorb vibration, thermal expansion, or slight misalignment. The conductor is tin-plated copper in a flat, flexible braid construction, and it's built to IEEE / ANSI C37, 34. Typical use is switchgear, disconnects, transformer and bus connections where a rigid bar would transmit stress into the equipment.

It's a 4-hole configuration, so each terminal pad takes four bolts rather than one or two. That matters when you're matching an existing NEMA-style drilled pad in switchgear: a 4-hole pad carries more current and resists rotation, but you can't land it on a single-hole stud without an adapter. Match the hole pattern on your equipment pad before ordering.

The conductor is tin-plated copper, and the tin plating is there to slow oxidation on the copper strands and at the bolted interface, which is why braids of this type are used in outdoor pad-mounted and substation gear as well as indoors. Tin plating also makes the braid safer to bolt directly to aluminum or plated bus without the galvanic problem you get from bare copper.

Use the braid when the two terminations move relative to each other: breaker racking, switch blade travel, thermal growth across a long bus run, equipment vibration, or seismic movement. The SWC215A1755 is a flexible flat braid, so it flexes without loading the terminals. Use a solid bar only where both pads are rigidly fixed and aligned, because a bar transmits every bit of that movement straight into the insulators and pads.

It is sold each as a single braid assembly, so plan on supplying your own bolts, belleville washers, and nuts sized to the four holes in each pad. Most switchgear specs call for a specific bolt grade and torque at bus joints, so pull the hardware and torque value off your equipment drawing rather than reusing whatever came out of the joint.

Country of origin is the United States, which is what a government, utility, or federally funded project needs to see for domestic content requirements. The part number to cite on submittals is Blackburn SWC215A1755.

It's built to IEEE / ANSI C37, 34, the standards family covering high-voltage air switches and their connection components. If your spec section calls out C37 connection hardware, cite Blackburn SWC215A1755 with that standard reference.

No. A braid assembly like this is terminated at both ends into 4-hole pads, so cutting it destroys one termination. Order the length that matches your span, in this case 755 mm, and take up any extra with a gentle loop rather than trimming or bending the pads.
