Blackburn EXA100A32600 EX-FLEX BRAID TNCU 1000A 1H 2600MM

The EXA100A32600 braid measures 2600 mm overall, listed as a 102 inch cable length. That is a long run for a flexible connector, so it suits substation bus jumpers and switchgear connections where the two terminations are several feet apart rather than tight bus-to-bus taps.

One-hole means a single bolt per terminal pad, so it lands on a bus bar or equipment pad with one fastener at each end rather than a two-hole NEMA pattern. If your drawing calls for a two-hole pad with 1-3/4 inch center-to-center spacing, this one will not match and you need a 2-hole braid instead.

It is a tin-plated copper braid. The tin plating is what keeps the copper strands from oxidizing at the surface, which matters in outdoor switchyards and damp vaults where bare copper braid would dull and add contact resistance over time.

A flexible braid absorbs thermal expansion, vibration, and small misalignment between two fixed terminations, which solid bus cannot. The EXA100A32600 is a flat, flexible conductor, so it also takes bends in one plane and lies tight against a bus pad instead of standing off the way round cable does. Typical uses are switch shunts, transformer-to-bus jumpers, and ground connections that have to move.

It is a 1000 amp braid connector, which is what puts it in substation and heavy switchgear service rather than panelboard work. Confirm the pad current rating on the equipment it is landing on matches.

The braid arrives as the conductor with its terminal pads; the bolts, flat washers, Belleville washers, and nuts that land it on the bus are ordered separately to suit the pad thickness and hole size at your equipment. Plan on one set per end, since each terminal takes a single bolt.

It is sold each, one braid per unit, so order one per connection point. Blackburn makes it in the United States.
