Blackburn FBE2H150A1-18 XFLEX BRAID 2 9/16H 1/2X1.5 X 18 IN

It's a two-hole extra flexible braid connector, 18 inches long, built as a flat flexible tin-plated copper braid. Parts like this bridge a connection where the two ends move relative to each other or need to absorb vibration and thermal expansion, such as switchgear and disconnect connections, bus-to-bus jumpers, and bonding across an expansion joint. The braid construction carries current while flexing; the two-hole flat pads at each end bolt to the equipment.

Yes. The FBE2H150A1-18 is built to CEI60694 and IEEE/ANSI C37.34-1994, the standards a utility or plant electrical spec normally calls out for high-voltage enclosed switch and switchgear connectors. If your drawing cites C37.34, this braid answers it directly. It's also made in the United States, which matters where a Buy American or domestic-content requirement applies to the project.

The full designation reads XFLEX BRAID 2 9/16H 1/2X1.5 X 18 IN: two 9/16 inch holes per pad, pad dimensions given as 1/2 x 1.5, and an overall length of 18 inches. The 9/16 inch holes take 1/2 inch bolt hardware with clearance. Bolts, washers, and nuts are not part of the braid, so order that hardware separately along with any joint compound your spec requires.

Use the braid wherever the two terminations are not fixed with respect to each other. A rigid bar or flat copper connector transmits every bit of vibration and thermal growth straight into the bolted joint and the equipment bushing, and eventually loosens or cracks it. This 18 inch flat flexible tin-plated copper braid takes that movement instead, which is why it is the normal choice for switch and breaker connections, movable bus sections, and expansion joints. Where nothing moves and the run is short, a rigid connector is simpler and cheaper.

The tin plating is exactly what makes that joint acceptable. Bare copper against aluminum sets up galvanic corrosion at the contact faces; tin plating over the copper braid is the standard barrier used to keep copper-to-aluminum bolted connections stable, and it also slows oxidation on the copper itself in outdoor and damp switchyard locations. Use the joint compound and torque your equipment manufacturer calls for.

Sold each. One FBE2H150A1-18 braid per unit, so a connection needing a braid on each phase takes three, and a spare kept on the shelf is a separate line. Useful to know if you are stocking an MRO crib rather than buying for a single outage.
