JUNW DTL-F Copper Aluminum Transition Lug Square Head Connector

JUNW DTL-F Series Square-Head Copper-Aluminum Transition Lugs
1. Copper-Aluminum Corrosion-Resistant Connection Solution
JUNW DTL-F lugs are purpose-built transition connectors for power systems, engineered to link aluminum-core cables with copper-based equipment (circuit breakers, distribution cabinets, and switchgear). By eliminating direct copper-aluminum contact, they prevent galvanic corrosion that causes connection degradation, overheating, and premature failure.
2. Friction-Welded Bond for Stable Conductivity
Manufactured with precision friction welding technology, the copper and aluminum sections are fused into a seamless, monolithic unit. This eliminates gaps and ensures uniform electrical conductivity, minimizing contact resistance and reducing the risk of overheating under continuous or variable loads.
3. Square-Head Design for Equipment Compatibility
The square copper terminal end is tailored to fit standard copper equipment terminals, ensuring a secure, low-profile connection in tight distribution panel spaces. The crimpable aluminum barrel accepts aluminum conductors, providing strain relief and maintaining connection integrity during installation and thermal cycling.
4. Comprehensive Size Range for Versatile Applications
Available in sizes from 16mm² to 500mm² (DTLF-2-16 to DTLF-2-500), these lugs accommodate diverse aluminum cable cross-sections, making them ideal for residential, commercial, and industrial power projects. They deliver long-term, maintenance-free performance, enhancing the safety and reliability of copper-aluminum power connections.
