Tinned Copper Cable Lugs
Tinned Copper Cable Lugs are high-conductivity electrical connectors designed for terminating stranded copper conductors to busbars, switchgear, transformers, and circuit breakers. Manufactured from high-purity electrolytic grade copper (99.9% Cu) and finished with a electro-tin plating, these lugs deliver maximum electrical efficiency and long-term protection against atmospheric oxidation and corrosion.
Key Features & Benefits
- High-Purity Electrolytic Copper: Crafted from high-conductivity copper to minimize electrical resistance, voltage drop, and thermal power loss.
- Corrosion-Resistant Tin Plating: Electro-tinned coating protects the underlying copper from oxidation, moisture, and chemical corrosion in humid or industrial environments.
- Precision Annealed Barrel: Seamless tubular design is fully annealed to prevent cracking or splitting during heavy-duty crimping with mechanical or hydraulic tools.
- Inspection Hole Option: Available with or without an inspection window to visually confirm complete conductor insertion prior to crimping.
- Bell-Mouth Entry: Features a flared or chamfered entry barrel for effortless insertion of flexible and multi-stranded conductors.
