  • Electrical contact element for medium or high voltage electrical equipment, and corresponding, method and equipment
    Patent number: 7677915
    Abstract: An electrical contact member, suitable for electrically interconnecting two conductive members in series, which members can move relative to each other and are part of an electrical apparatus. The electrical contact includes a strength-imparting base layer made of an electrically conductive material, and a coating layer formed from metallic silver and configured to come into contact with the two electrically conductive members. The coating layer has a micro-structure formed by pure silver crystals, with a presence of nodules made of silver and of an additional metallic material formed by at least one additional metal that is different from silver.
