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.
- 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.
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.
