Flexible connectors for transformers
IZAR makes braided and laminated copper connectors that link transformer terminals to busbar trunking or switchgear without passing on vibration.
Where it works
From terminals to busbar trunking
The connector links the transformer terminals to busbar trunking or to switchgear busbars. Braided connectors are also used in oil-filled transformers.
What it has to withstand
Vibration
A loaded transformer vibrates. The flexible connector keeps that vibration off the busbar trunking.
Offset axes
Terminals and trunking rarely share an axis. Z, U and L shapes bridge the offset.
High current
The low-voltage side carries the highest currents. The cross-section comes from the PG and PE tables.

Questions
Choosing the right connector
What length of PG connector should I order for a transformer?
The terminal spacing plus 30–60 mm. A braided connector should not be taut; the extra length makes fitting easier and leaves room for movement if distances in the system shift slightly.
PG or PE at a transformer?
PG where the terminals are offset or the connection moves in several directions. PE where movement is small and space between bars is tight, because at the same cross-section its terminal is about 40% lower. PE is also slightly cheaper than PG.
Can a PG connector be insulated?
Yes: a PVC or silicone insulating hose or a heat-shrink sleeve. Insulation limits heat dissipation, so it is worth choosing the cross-section with some margin.
