DTL Bimetallic Cable Lugs – Product Technical Report 1. Product Name DTL Bimetallic Cable Lugs (Copper–Aluminum Compression Terminals) 2. Product Description DTL lugs are electrical termination components designed to connect aluminum conductors to copper busbars or copper terminals. They provide a reliable transition between dissimilar metals, preventing galvanic corrosion and ensuring stable current flow. 3. Material Composition • Aluminum Barrel: 99.6% pure aluminum (excellent conductivity, lightweight) • Copper Palm: High-conductivity electrolytic copper, tin-plated • Joint Welding: Friction-welded Al–Cu interface 4. Key Features • Suitable for connecting aluminum cables to copper terminals • Stable electrical performance with low contact resistance • Corrosion-resistant Cu–Al interface • Smooth internal barrel for easy crimping • Strong mechanical strength • Available in multiple cable sizes 5. Applications • Power distribution systems • Electrical panels and switchgear • Industrial equipment • Transformers • Renewable energy installations 6. Installation Method 1. Strip cable insulation properly. 2. Insert conductor fully into barrel. 3. Crimp using a hex or indent tool. 4. Bolt the copper palm to terminal. 5. Ensure proper torque and continuity. 7. Available Sizes DTL-10, DTL-16, DTL-25, DTL-35, DTL-50, DTL-70, DTL-95, DTL-120 and larger sizes. 8. Standards & Compliance • IEC 61238-1 • DIN 46329 • GB/T 14315 9. Advantages • Reduces Cu–Al corrosion • High electrical conductivity • Durable welded structure • Suitable for high-current applications • Long service life
