The bolted joint transition washer, designed and developed by the Central Electricity Research Laboratories, is manufactured by Sicame Electrical Developments Limited. The device consists of a sharply profiled copper alloy washer encapsulated in a protective grease. When inserted between the mating faces of a bolted joint the sharp profile penetrates surface oxide films and the grease is extruded to form a seal against corrosion.
