Blackburn EXH150A1277 – Frequently Asked Questions
1) What is the Blackburn EXH150A1277 flexible braid connector rated for and where is it used?
The EXH150A1277 is a 1500 amp extra flexible braid connector with four bolt holes, built to IEEE/ANSI C37.34 for high voltage air switch applications. It is the flexible link used between rigid bus, switch blades, or equipment terminals where movement, thermal expansion, or vibration would stress a solid connection.
2) How long is the Blackburn EXH150A1277 braid connector?
277 mm, which is 10.91 inches, measured as cable length. That is the overall length you have to work with between the two bolted pads, so confirm your terminal centers fall inside it before ordering, since braid connectors are not field-lengthened.
3) Do I need a 4-hole flexible braid connector or will a 2-hole work?
Hole count follows the pad drilling on the equipment you are landing on. The EXH150A1277 has four holes, which matches NEMA 4-hole bus pad drilling typical of higher current gear, and at 1500 amps that is the usual pattern. If your switch or bus pad is drilled for two holes, a 4-hole braid will not line up, so match the pad.
4) What is the conductor material on the Blackburn EXH150A1277 flex connector?
Tin-plated copper braid in a flat conductor shape. The tin plating resists oxidation at the bolted pads, and flat braid gives more surface area for heat dissipation and stays flexible in the plane of bending.
5) Is the Blackburn EXH150A1277 flexible enough for switch blade movement?
Yes. The conductor category is Very Flexible and the construction is flexible braid rather than laminated bar or solid copper, so it takes repeated movement such as a disconnect blade travelling or bus expanding and contracting with load and temperature.
6) Does the EXH150A1277 braid connector come with bolts and hardware?
It is sold as a single connector, each. Bolts, Belleville washers, nuts, and any joint compound for the bolted connections are separate items, so add the hardware your pad drilling and torque spec call for when you place the order.
7) What is the exact part number to order this 1500 amp Blackburn flex connector?
Order Blackburn EXH150A1277. The EXH prefix is the extra flexible braid series, 150A reads as the 1500 amp rating, and 1277 is the 277 mm length, so the length and ampacity are both carried in the number.
8) Is the Blackburn EXH150A1277 made in the USA?
Country of origin is the United States, which matters if you are procuring against a domestic-content requirement on a utility or public works project.
