Blackburn SWB105A1508 FLEX BRAID 1050A 2H 1H 44.4X508MM

The SWB105A1508 braid measures 508 mm, which is 20 inches, end to end. That length is fixed, so if your bus-to-bus or transformer-to-switchgear span needs more flex slack than 20 inches gives you, step up to a longer braid rather than stretching this one taut. Braid connectors are meant to be installed with a gentle bow so thermal movement and vibration are absorbed by the braid, not by the bolted pads.

The conductor is tin-plated copper braid. Tin plating over copper slows oxidation on the strand surfaces and at the bolted pads, so it holds contact resistance better than bare copper in humid, outdoor, or industrial atmospheres. It is still copper for conductivity, just protected at the surface.

A braid like the SWB105A1508 is a flat, flexible conductor, so it absorbs thermal expansion, settling, and vibration between two rigid bolted points that a solid bus bar link would transmit straight into the joint. Compared with a round cable jumper, the flat braid profile takes up less depth in tight enclosures and bends in one plane, which makes it easier to route around a gear front. Use solid bus when you need mechanical support; use braid when the two ends move relative to each other.

Country of origin on the SWB105A1508 is the United States. That is the documented origin for a submittal package on a federal, state, or institutional job with domestic-content language, though the awarding agency decides which specific rule applies to your contract.

The SWB105A1508 is supplied as the braid assembly with its two-hole pads, one piece per order. Bolts, nuts, flat and Belleville washers for the pad connections are not part of the item, so pick those up separately to suit your bus hole size and pattern.

Sold each. The selling unit of measure on the SWB105A1508 is one piece, so order one per connection point. On a three-phase set plus neutral you would be ordering four.
