Blackburn EXH140A1304 EX-FLEX BRAID TNCU 1400A 4H 304MM

It is a 1400 amp flexible braid connector, built to IEEE/ANSI C37.34, the standard covering test code for high-voltage air switches. That rating is the continuous current the braid is designed to carry between bus or switch terminals, so match it against the bus ampacity it is bridging rather than the load alone.

Four. It is a 4-hole braid connector, so each end pad takes a four-bolt pattern. If the switch or bus pad you are landing on is drilled for two bolts, this pad will not line up with it and you want the matching 2-hole braid instead.

The conductor is tin-plated copper. The tin plating is what lets a copper braid be bolted to an aluminum bus pad without the bare copper-to-aluminum galvanic couple, and it also slows oxidation on outdoor substation terminations.

A flexible braid takes movement that solid bus cannot. The conductor here is flexible and flat, which gives a low-profile connection that flexes across its width for thermal growth, seismic movement, and the travel of a switch blade, while keeping a bolted four-hole pad at each end. Rigid bus bar transmits that stress straight into the insulator and terminal; a round cable jumper flexes but does not sit flat against a pad the way a braid does.

Country of origin is the United States, which is what utility and government procurement specs usually want documented on substation connectors. It is also built to IEEE/ANSI C37.34, the reference most switch and bus specifications cite for this class of hardware.

EXH140A1304. That designation breaks down to the extra-flexible braid family, 1400 amps, four-hole pads, and 304 mm length, all in tin-plated copper. Quote it exactly as EXH140A1304 to avoid landing on a different ampacity or hole pattern in the same series.

It sells each, so one order quantity gets one 1400 amp braid. Substation work usually needs one per phase, so a three-phase switch position takes three, plus spares if you are standardizing a yard.
