Blackburn SWC215G3915 SWG XFORM LINK 2150A 2VH 915MM

The SWC215G3915 is a switchgear transformer link rated 2150 amps, built as a flat flexible braid of tin-plated copper with a four-hole pad at each end. It is made to IEEE/ANSI C37.34, the standard covering high-voltage air switches and switchgear connections, so it is intended for switchgear and transformer bus terminations rather than general building wiring.

Each end of the SWC215G3915 terminates in a four-hole pad, the arrangement used on switchgear and transformer terminal pads at this current class. Hole spacing and pad size are not something to assume from the amp rating alone, so match the pads against the drilling on your transformer terminal or bus bar before you order. Two-hole and NEMA four-hole patterns are not interchangeable.

A rigid bar transmits vibration and thermal expansion straight into the terminal pads and the transformer bushings. A flat flexible braid like the SWC215G3915 absorbs that movement while carrying 2150 amps, and it lets you take up small misalignment between a transformer pad and switchgear bus without machining the bar. Where the connection is fixed, aligned, and static, a solid bar is simpler; where anything moves, the braid is the correct part.

It is sold each. A three-phase connection needs three links, so order in multiples of three, and add spares if your outage window leaves no time to chase a fourth. The part number to specify is SWC215G3915.

Country of origin on the SWC215G3915 is the United States, which is what a utility, municipal, or federally funded project needs on the submittal. It is also built to IEEE/ANSI C37.34, so the standards line on your spec sheet is covered by the same part.

The conductor is tin-plated copper. Tin plating slows oxidation on the braid and the contact faces, which matters in humid or outdoor pad-mount enclosures where bare copper dulls and contact resistance climbs. Standard practice still applies: clean the mating pad and torque to the switchgear manufacturer's figure.
