HTS Current Leads

With over a thousand HTS current leads in the field the CryoSaver™ have demonstrated outstanding, time-tested performance for more than a decade. CryoSaver™ leads outperform competing solutions with unsurpassed build quality, mechanical strength and performance.

CryoSaver™ second generation of current leads, CryoSaver™ II, rated from 150A to more than 2000A, deliver significantly improved performance with lower heat leak, reducing heat-load and losses for client’s systems. Applications include MRI, NMR and beamline magnets as well as driven (non-persistent) superconducting magnets.

HTS Current Leads features:

 Low Heat Leak:

  • The composite conductor consists of HTS filaments in a low thermal conductivity matrix, providing a very high current density and low heat leak through the small cross-section.

Field Tolerant:

  • The anisotropic nature of the CryoSaver™ current leads allows the lead to be positioned in a cryostat such that applied fields are along a favourable axis, an advantage over isotropic bulk materials.

Ease of Integration:

  • Electrical connection to the caps is easily made, mechanically or by soldering, for low resistance and low Joule heating Leads are available in a number of formats:

Standard and short leads

Standard CryoSaver™ leads use a fiberglass composite body to encase the HTS wire for structural integrity. Nickel plated copper end-caps are used for warm and cold end connections. Shorter versions of standard current leads are available for space constrained applications.

Hermetic leads

Designed for service in cryogenic liquid or vapour, CryoSaver™ Hermetic leads utilize a thin-walled stainless steel outer body and lid to form a hermetic seal against absorption of helium into the HTS wire.


CryoSaver™ current leads which include custom terminals, specific dimensions, complex geometry and high current (>10kA), can be designed and manufactured to meet client requirements.
