Electrical contact materials based on AgCdO with CdO as the main active component have proven to be particularly advantageous for low voltage switchgear in the power industry. However, when switching AgCdO contact materials, CdO, which is classified as toxic, can escape into the environment through burn-off. It is important, therefore, to keep the CdO content as low as possible in the contact mate...
