Blackburn EXA035A1304 EX-FLEX BRAID TNCU 350A 1H 304MM

304 mm, which is 12 inches. That length is the overall cable length of the braid, so plan your terminal-to-terminal span around it rather than assuming you can stretch it. If your two pads sit farther apart than a 12 inch braid will reach without tension, step up to a longer braid length in the Blackburn EX-FLEX range.

One hole per pad. If the equipment or bus pad you are landing on is drilled for two bolts on NEMA spacing, a single-hole braid will not give you the required two-point connection, and you need the 2-hole version of the EX-FLEX braid instead.

It is built to IEEE / ANSI C37, 34, the standard referenced for high-voltage air switch and switchgear connector hardware, which is the line a spec reviewer normally wants to see on a flexible bus jumper. Country of origin is the United States, which matters on Buy American and domestic-preference work.

It's a flexible braid connector for bonding and jumper connections between rigid bus or equipment terminals, where movement, vibration, or thermal expansion has to be absorbed. The conductor is a flat, very flexible tin-plated copper braid, and the connector is built with a single bolt hole at the termination. Blackburn builds it to IEEE / ANSI C37, 34.

The braid conductor is tin-plated copper. Tin plating is what makes it acceptable against aluminum as well as copper pads, which is why switchgear specs call for plated braid rather than bare copper at dissimilar-metal joints. Clean the mating surface and use an appropriate joint compound at aluminum terminations.

A flat braid flexes in service. Where a rigid bus link transmits vibration and thermal movement straight into the terminal, and a round cable jumper resists bending in one plane, a flat very-flexible braid takes repeated movement and expansion without loading the pads. Use braid at expansion joints, transformer and breaker terminations, and anywhere equipment shifts. Use rigid links where the connection is static and you want the mechanical stiffness.

Blackburn EXA035A1304 is the manufacturer part number for the 350A, 1-hole, 304 mm extra flexible tin-plated copper braid. Quote that number when matching an existing installation so you get the same amperage rating, hole count, and length.

Sold each. Order one per connection point, and remember a jumper pair or a three-phase set needs a matching quantity, plus the bolts, nuts and washers for the pads, which are not part of the braid itself.
