Blackburn EXH140A1330 FLEXIBLE BRAID LENGTH 330MM

It's an extra flexible braid connector with four bolt holes, used as a flexible bonding or grounding jumper between two bolted terminations. The conductor is a flat tin-plated copper braid, so it carries current across a joint while still allowing movement, vibration, or thermal expansion between the two connected points. Sold individually.

Not without an adapter. The EXH140A1330 has four holes per terminal pad, so the equipment pad or lug you bolt it to needs a matching four-hole pattern. If your gear has a two-hole NEMA pad, either use a two-hole braid instead or bolt through an adapter plate that converts the pattern. Match the hole spacing and diameter before you order.

The tin plating on the EXH140A1330 braid protects the copper strands from oxidation and is the usual choice where the braid mates to aluminum or galvanized hardware, since it reduces the corrosion you get from dissimilar metal contact. Bare copper works fine in clean dry indoor joints but tarnishes faster in damp or outdoor terminations.

Use the flat braid where the connection has to flex. The EXH140A1330 is an extra flexible flat braid, so it tolerates repeated movement and vibration far better than a stranded cable jumper of the same length, which stiffens at the lugs and work-hardens. Typical calls for braid are switchgear doors, transformer and busbar joints, expansion joints, and equipment on isolators. For a static bond between two fixed points, a plain cable jumper is simpler.

Only the braid itself is supplied, one per order. The four holes in the flat terminal pads take your own hardware, so order the bolts, flat washers, lock washers, and nuts to suit the bolt pattern and hole size on the equipment you are landing it on.

The manufacturer part number is EXH140A1330, Blackburn brand. The 1330 suffix corresponds to the 330 mm braid length, so if you need a different span, look for the same EXH140A series in the length you want.

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