Aluminum Copper Bimetal, Size : 300mmx300mm, 300mmx600mm, 300 Mm Width

Aluminum Copper Bimetal Terminal consists of copper (sheet metal) cladded on pure Aluminium (base metal), both metals being diffused together to form an inseparable whole by roll bonding process. Bi-metal, is therefore not an alloy and copper layers are not Electro plating / galvanic coatings but are rather mechanically welded on Aluminium with Copper sheets. Aluminium Terminals are directly connected to Copper Terminals to carry current at a high voltage, a bimetallic galvanic corrosion occurs, resulting in a high resistance at the joint. The heated joints are oxidized and losses contact resulting in sparks, voltage dropout power losses and failure, damage to machinery. When bimetal is placed between Aluminium Terminal and Copper Terminal at the joint (with Copper facing Copper and Aluminium facing Aluminium), bimetallic galvanic corrosion is averted due to absence of air in bimetal. Bi-metal is thus used at dissimilar metals joints of Aluminium and Copper to make similar metal's contact. BimMetal has been successfully evaluated and used by many of the world's leading electrical equipment manufacturers. Aluminium - Copper Bi-Metal Terminals : AI-Cu bi-metal terminal are used for connecting aluminium cable to copper busbars. Bimetal washers to prevent bimetallic galvanic electro-corrosion at copper and Aluminium joints Applications include the following: Apparatus construction As packing & washers bet aluminium & copper bars Bimetallic clamp & connectors Busbar chambers Busducts Cable clamp Cable end connectors Cable thimbles in copper Circuit breakers Current bars & similar parts Distribution and panel boards Isolators Motor control centers On overhead lines Overhead busbar trunking systems Overhead connectors Panelboards Sleeve shape insert in terminals in copper & aluminium Substation accessories like bimetallic clamp and connectors Switch blades Switch plant Switchgears Terminal stirps
