Convection w. HTS (CvHNH).
- Current: 2-70 kA
- Coolant: LHe + GHe/LN2
The CvHNH is similar to the CvHH, but here liquid nitrogen (LN2) is introduced to cool the resistive part of the current lead (section 1 (see sketch)). When the design specification allows for LN2 to be used as a coolant, the helium consumption can be significantly reduced. This design is used for operating currents of 2-70 kA.
