Blackburn FBE1H035A1-20 XFLEX BRAID 9/16H 3/16X1.5 X 20 IN

Cable length is 20 inches, and the terminal pads are drilled 9/16 inch, which takes a 1/2 inch bolt with clearance. The braid section itself is described as 3/16 by 1.5 inches. Measure the installed span before ordering, since braid should be installed with some slack so the movement it is absorbing is taken by the braid and not by the bolted pads.

The FBE1H035A1-20 is built to CEI 60694 and IEEE/ANSI C37.34-1994, the standards that cover high-voltage switchgear and switchgear connection testing. That is the citation an engineer or inspector will look for on substation and switchgear bonding submittals.

It's a flat, extra-flexible tin-plated copper braid connector with a single bolt hole at each end, used to bond or jumper between two points that move relative to each other, expand and contract, or need vibration isolation. Typical work is switchgear, substation bus, disconnect switches and transformer connections, where a rigid bar would fatigue and crack. The braid construction carries current while absorbing that movement.

Flat braid and round flexible cable do different jobs. This connector is flat in shape, which gives more surface area for heat shedding in a shallow space and flexes readily across its thickness, so it suits tight switchgear cubicles and connections that move in one plane. A round flexible cable jumper bends in any direction and is the better choice when the movement is not in a single plane or the run has to snake around obstructions. For bolted pad-to-pad bonding on gear, the flat braid with drilled terminals like this one is the usual fit.

No hardware is included. The braid ships as the connector only, with 9/16 inch drilled pads at each end, so you supply the bolt, nut, and washers (a 1/2 inch bolt fits the hole) along with any Belleville washers your gear spec calls for.

The conductor is tin-plated copper. The tin plating slows oxidation on the braid strands and the bolted pad faces, which keeps contact resistance down over time and makes the connection more tolerant of damp or industrial atmospheres than bare copper. It also avoids the galvanic issue you get bolting bare copper directly to aluminum bus.

Sold as each, one braid per unit, under part number FBE1H035A1-20. Order one per connection point you are jumpering.

Country of origin is the United States, which matters if you are buying against a Buy American or domestic-preference clause on a government, utility or institutional project.
