Overview

The ABB ATT 2-2 Aluminum Tapered Tee, part of ABB's Installation Products catalog, is designed for reliable electrical connections. This tee connector is engineered to join two conductors, with a main conductor and a tap conductor, both specified as 2/0 Stranded Aluminum-Copper (AL-CU). The main conductor connection point measures 2-3/8 inches, while the tap connection point extends to 5-1/2 inches. A key feature is the dimple located at 2-3/7 inches on the tap, which aids in ensuring a secure and consistent connection by providing a defined pressure point. This product is compatible with a specific set of dies: TU, 52, BG, 243, and 5/8. The inclusion of an oxide inhibitor is crucial for maintaining electrical conductivity and preventing corrosion over time, especially with aluminum conductors. The tee comes with red caps, likely for protection during shipping and handling, and to indicate the tap end. With UNSPSC code 39121409, this component is categorized under electrical connectors and fittings. The use of stranded AL-CU conductors signifies its application in power distribution and transmission systems where flexibility and conductivity are paramount. The tapered design allows for efficient use of space and a robust mechanical connection. This ABB product (SKU: ATT 2-2) offers a dependable solution for creating branched connections in electrical infrastructure.
