Blackburn FB2D18 FLEXIBLE BRAID 153.6KCMIL 18IN LONG

It is 18 inches long and rated 153.6 kcmil. That cross-section sits between 3/0 and 4/0 AWG in copper equivalence, so it is commonly used where a 3/0 bonding jumper is specified but the connection has to move.

The FB2D18 is a flat flexible braid connector with two bolt holes, used to bond or jumper between two points that need a flexible connection: across expansion joints, bus sections, transformer or motor bases, switchgear doors, and equipment that vibrates or moves. The braid construction lets the connection flex without work-hardening a solid conductor, and the two-hole pattern keeps the termination from rotating under torque.

The braid is tin-plated copper. The tin plating resists oxidation and galvanic issues where the braid lands on aluminum or galvanized bus, which is why tinned braid is the usual pick for outdoor enclosures, wet process areas, and utility yards rather than bare copper.

No. The FB2D18 ships as a single braid with the two-hole terminations already formed on it, sold each. Bolts, nuts, flat and Belleville washers, and any antioxidant compound for aluminum landings are separate line items you need to add to the order.

Use a braid like the FB2D18 wherever the two connected points move relative to each other: expansion joints, vibration isolators, hinged panels, generator and transformer bases. A stranded cable jumper is fine for static bonding and is easier to route in tight bends, but repeated flexing will fatigue it. The braid is flat, which also lets it sit tight against a bus or frame where a round cable would stand off.

Country of origin is the United States, which is what procurement usually needs to see on federal, utility, and institutional projects with domestic-content requirements.
