Blackburn EXA035A1152 EX-FLEX BRAID TNCU 350A 1H 152MM

It's a flat, extra-flexible tin-plated copper braid used as a shunt or jumper connection between two bus or equipment pads, typically on switchgear, disconnects and grounding bus where the two terminations need to move relative to each other or absorb vibration and thermal expansion. The braid construction carries current while flexing, which a solid bar or a lug-and-cable run will not do. It has a single bolt hole at each end and is sold individually.

Six inches, or 152 mm, overall. That is the dimension that decides whether it spans the gap between your two pads, so measure hole center to hole center on the existing connection before ordering; a 6 inch braid will not bridge a longer pad spacing and forcing it defeats the point of using a flexible shunt.

One hole per pad. It's catalogued as an extra flexible braid connector, 1-hole, so each end takes a single bolt. If your existing bus pad is drilled two-hole on NEMA spacing, this braid will only pick up one of those holes and you should specify a 2-hole braid instead.

It is built to IEEE/ANSI C37.34, the standard covering high voltage air switches and their connection components. That is the reference a utility or substation spec normally calls out for flexible shunt connectors, so it answers the submittal question directly.

The tin plating on the EXA035A1152 braid resists oxidation at the contact faces and in the braid strands, which matters outdoors, in substations and in damp or corrosive plant air where bare copper dulls and contact resistance climbs. It also mates to aluminum or plated bus without the galvanic concerns of bare copper against aluminum.

Not where the connection has to flex. Stranded cable with crimp lugs handles a fixed span fine, but it stiffens at the lug barrel and fatigues at that point under repeated movement. The EXA035A1152 is a flat flexible braid, so the flex is distributed along the whole 6 inch length, which is what a disconnect blade, expansion joint or vibrating equipment pad needs.

Yes, country of origin is the United States. That matters if you're buying for a federal, utility or transit job with domestic sourcing language in the spec.

Single piece. The selling unit is each, so order one per connection point; a disconnect or bus joint needing shunts on multiple phases takes one braid per phase.
