Blackburn SWC215E3915 SWG XFORM LINK 2150A 2H 915MM

The SWC215E3915 is a 2150 amp switchgear/transformer link, built as a flexible braid connector with a two-hole pad on each end. That rating comes from the braid cross section as supplied, so it is sized for main bus and transformer-to-switchgear terminations at that ampacity rather than feeder-size tap work.

Both ends are two-hole pads. That gives a bolted connection that resists rotation under fault current and vibration, which is the reason two-hole prep is specified on switchgear and transformer terminations. Confirm your pad hole spacing and bolt size matches before you schedule the outage.

A braid link absorbs movement. Transformers vibrate and both the transformer and the switchgear bus expand and contract thermally, and a rigid bar transmits all of that straight into the bolted pads. The SWC215E3915 uses a flexible flat braid conductor, so it takes up misalignment between pads and isolates vibration while still carrying 2150 amps. Use solid bar where the two pads are fixed, aligned, and not subject to movement.

The SWC215E3915 is manufactured to IEEE/ANSI C37.34, the standard covering high-voltage air switches and their connections. That is the reference a utility or institutional spec writer usually calls out for switchgear connectors, so it can be submitted against a drawing citing C37.34 without substitution paperwork.

The conductor is tin-plated copper braid. The tin plating is what matters at the pad: it slows oxidation on the bolted surface and is the accepted plating for bolting copper to aluminum bus, which bare copper should not be done to directly. Use the appropriate hardware and a joint compound per your bus manufacturer's torque spec.

Order Blackburn SWC215E3915. The number reads out as the spec: 2150 amp rating, two-hole pads both ends, 915 mm length, flat flexible tin-plated copper braid. Adjacent numbers in the series change ampacity or length, so quote the full designation rather than a partial.

It ships as a single link, one each, made in the United States. Connections normally come in threes, so a three-phase transformer-to-switchgear termination needs three of them, plus a fourth if you are also linking a neutral.
