Coil Winding

General coil winding and associated items produced using our wide variety of machines and processes. Our speciality is perfect layer winding using copper wire as in the picture. Perfect layer or orthocyclic windings are produced by laying each turn of wire into the groove of the turns underneath. It is the most space efficient type of winding using round wire and has the best thermal conduction through the winding.

Superconducting windings

We have produced perfect layer superconducting coils up to 40,000 turns of 0.3mm superconducting wire where.it is essential that superconducting windings are perfectly layer wound in order to minimise the stress on each turn and prevent quenching.
