Blackburn SWD190D1304 – Frequently Asked Questions
1) What is the Blackburn SWD190D1304 switchgear link actually used for?
It's a flexible braid connector used as a transformer/switchgear link, carrying current between two bolted pads while allowing movement, thermal expansion and vibration isolation. The conductor is flat flexible tin-plated copper, and the connector is built as a 4-hole to 3-hole pad arrangement. It's built to IEEE/ANSI C37.34, the standard covering high-voltage air switches and their connecting hardware.
2) Will the Blackburn SWD190D1304 bolt to my existing pads, and do I need to match hole patterns?
Hole pattern matters more than anything else on this part. The SWD190D1304 is a 4-hole to 3-hole link, so one end lands on a four-hole NEMA-style pad and the opposite end on a three-hole pad. If both of your terminations are four-hole, this is the wrong link and you want a 4-hole to 4-hole version instead. Check the drilling on both ends of the run before ordering.
3) Why tin-plated copper instead of bare copper on a switchgear link?
The tin plating on the SWD190D1304 braid gives a stable contact surface at the bolted joint and resists the oxide film bare copper builds up, which is what drives joint resistance and heating over time. It also lets the link land against aluminum or tin-plated bus pads without a bare copper-to-aluminum couple.
4) Is a flexible braid link better than a solid bus bar between switchgear pads?
Use flexible braid where the two connection points move relative to each other: thermal growth in the bus, seismic or equipment vibration, or a disconnect switch blade that has to travel. The SWD190D1304 uses flat flexible construction for exactly that. A rigid bar is fine for a fixed, aligned run and is cheaper to fabricate, but it transmits stress straight into the pads and won't tolerate misalignment.
5) Does the Blackburn SWD190D1304 meet a recognized standard for switchgear connections?
It's built to IEEE/ANSI C37.34, the standard for high-voltage air switches and associated connection hardware. If your spec or submittal calls out C37.34 for flexible connectors, this link answers it.
6) Is the Blackburn SWD190D1304 sold individually or in a pack, and is it made in the USA?
Sold each, one link per unit, so a three-phase run takes three. Country of origin is the United States, which matters if you're buying under a domestic-preference or Buy American procurement requirement.
7) Does the Blackburn SWD190D1304 come with the bolts and hardware to land it?
The SWD190D1304 ships as the braid link itself. Bolts, Belleville washers and nuts for the bolted pad connections are ordered separately and should be sized to the pad drilling and torqued to your switchgear manufacturer's values.
