DTL-240-13 Bimetallic Lug

The DTL-240-13 is a heavy-duty bimetallic compression lug used to create a safe and reliable termination between a large aluminum cable and a copper busbar or terminal.

The “DTL” designation signifies it is a Copper-Aluminum lug. Its primary purpose is to prevent galvanic corrosion, a chemical reaction that occurs when aluminum and copper are in direct contact, which can lead to a failed connection over time.

Key Features:

• Friction Welded: The aluminum barrel and copper palm are joined using a high-pressure friction welding process, creating a strong and electrically stable bond.
• Corrosion Prevention: The barrel is typically pre-filled with an oxide-inhibiting jointing compound (grease) and capped to ensure a clean, air-tight, and corrosion-resistant connection when the cable is inserted and crimped.
• Application: Essential for power distribution, switchgear, transformers, and any high-current application where aluminum cables must be connected to copper equipment.
