Blackburn LTL400E3457 – Frequently Asked Questions
1) What bolt hole size and pattern does the Blackburn LTL400E3457 link have?
Six holes, 9/16 inch diameter, arranged vertical to horizontal, three at each end. That hole size takes 1/2 inch bolt hardware with normal clearance. Check your transformer bushing pad and bus pad drilling match a 6-hole NEMA arrangement before ordering, since the pad drilling is what decides whether the link lands flat.
2) Is the Blackburn LTL400E3457 flexible, or is it a solid bar?
Flexible. It is a flat flexible braid, not a rigid bar, so it absorbs transformer vibration and thermal movement between the bushing and the bus instead of transferring that stress into the porcelain. That is the main reason a link like this goes in rather than a drilled copper bar.
3) What is the Blackburn LTL400E3457 made of, and will it corrode on an outdoor substation?
Tin-plated copper. The tin plating is what lets it bolt to aluminum or copper pads without the galvanic problem bare copper creates, and it holds up to outdoor substation exposure better than an unplated braid. Standard practice still applies: wire brush the pads and use a joint compound rated for the metals you are joining.
4) What is the exact part number to order this Blackburn 6-hole transformer link under?
Order it as Blackburn LTL400E3457. That single number carries the whole configuration: large transformer link, 6-hole, vertical to horizontal, 9/16 inch holes, 12.7 x 152.4 x 457 mm. Substituting another LTL number changes hole count, hole size or length.
5) Is the Blackburn LTL400E3457 sold individually or in a pack?
Sold each. One link per order, so a three-phase transformer bank needs three, and you order bolts, washers and belleville hardware separately since none of that comes with the link.
