Compression Cable Lugs & Connectors
)
Construction & Materials Barrel Design
- Manufactured from seamless or forged high‑conductivity copper or aluminium to ensure uniform grain flow and superior mechanical strength.
- Optimised barrel wall thickness to achieve controlled deformation during crimping.
- Precisely dimensioned internal diameter to suit standard conductor classes (Class 2, 5, and 6).
Palm / Contact Area (for Lugs)
- Flat palm with machined or forged contact surface for maximum electrical contact.
- Palm thickness designed to withstand tightening torque without distortion.
- Optional inspection hole for conductor visual confirmation.
Surface Protection
- Electro‑tin plating (typically 8–20 μm) for corrosion resistance and compatibility with aluminium or tinned copper conductors.
- Smooth plated finish reduces oxidation and contact resistance over service life.
Electrical & Mechanical Performance
- Low Contact Resistance – Achieved through full circumferential compression.
- High Tensile Strength – Exceeds conductor breaking force when crimped correctly.
- Thermal Stability – Maintains performance under cyclic loading and temperature rise.
- Vibration Resistance – Permanent cold‑weld type joint prevents loosening.
