Blackburn SWA070A1457 – Frequently Asked Questions
1) What current rating does the Blackburn SWA070A1457 flexible braid connector carry?
It's a 700 amp flexible braid, built to IEEE / ANSI C37, 34. Use it where a 700A switchgear or bus connection needs a flexible shunt rather than a rigid bar.
2) Is the SWA070A1457 a one-hole or two-hole pad connector?
One-hole pads, so each end lands on a single bolt. If your bus or switch pad is drilled for two bolts on standard NEMA spacing, a 1-hole braid won't give you both fixings and you want a 2-hole version instead.
3) What is the Blackburn flex braid conductor made of, and will it hold up in a damp switchgear room?
Tin-plated copper, in a flat flexible braid. The tin plating is what slows oxidation at the contact faces, which is why these get specified in outdoor and humid substation enclosures over bare copper.
4) Why use a flexible braid connector instead of solid copper bar between bus sections?
A braid takes up thermal expansion, vibration and slight misalignment that a rigid bar transmits straight into the bolted joint. The SWA070A1457 is a flat flexible braid, so it also handles moving or hinged connections such as disconnect blades and transformer terminations where a bar simply can't flex. Where the geometry is fixed and nothing moves, a rigid bar is the cheaper choice.
5) Is the SWA070A1457 braid made in the USA for a Buy American job?
Country of origin is the United States. That's the data point a government, transit or utility procurement office needs when a domestic-content clause is on the contract.
6) What is the exact part number to order this Blackburn 700A flex braid?
Blackburn SWA070A1457. The number reads out as the spec: 070A for the 700 amp rating, 1 hole pads, and 457 mm of length.
7) Is the Blackburn SWA070A1457 sold individually or in a pack?
Sold each, so one braid per order line. Count your jumpers per phase before ordering a three-phase set.
