Blackburn LTL400A1457 – Frequently Asked Questions
1) What is the Blackburn LTL400A1457 transformer link actually used for?
It is a large 4-hole flexible braid link connector, made of tin-plated copper in a flat conductor shape. Links like this bridge a transformer bushing or pad to a bus or cable terminal while allowing movement between the two points, so thermal expansion, vibration, and slight misalignment are absorbed by the braid instead of stressing the terminations. Sold each.
2) Does this Blackburn link meet IEEE or ANSI standards for substation connectors?
It is built to IEEE / ANSI C37 and 34. That is the reference an engineer or utility inspector will want on a switchgear or substation submittal for a flexible transformer connection.
3) Why choose a flexible braid link instead of a solid copper bus bar between a transformer and its bus?
A solid bar transmits every bit of movement straight into the bolted joints. The LTL400A1457 uses a flexible braid conductor, so transformer vibration, thermal growth of the bus, and small install misalignments are taken up by the braid. Pick a rigid bar where the geometry is fixed and nothing moves; pick a flexible braid link at the transformer termination, where movement is guaranteed.
4) Is the tin plating on this transformer link necessary, or would bare copper be fine?
The conductor is tin-plated copper. Tin plating slows oxidation on the bolted contact faces, which keeps joint resistance stable over time, and it is what lets the link be bolted to aluminum bus or aluminum transformer pads without setting up a bare copper-to-aluminum couple. Bare copper braid is generally kept to copper-to-copper joints in dry indoor conditions.
5) Is the Blackburn LTL400A1457 made in the USA, and does it ship as a single piece?
Country of origin is the United States, and the selling unit is each, so one order quantity is one link. On a three-phase transformer termination you will need one per phase, plus any neutral connection.
