Potential Breaks
Our potential breaks are manufactured according to the proven Lenz-Technology and under very strict QA measurements. They show a very good HV-capability and especially an outstanding pressure tightness for He even after numerous thermal cycles. The research projects Wendelstein 7-X and the ITER-TF model coil are equipped with potential breaks mark BNG. Also in novel accelerator magnets such as the first SIS100 dipole prototypes for the FAIR project our potential breaks are used. |

By means of potential breaks an electrical separation of high pressure cooling channels for liquid Helium is established. This function is required especially for superconducting magnets used in nuclear fusion research.
