Cable Lug for 70 mm² Conductor – 10 mm Mounting Hole, Tin-Plated Copper
Pickup currently not available
Detailed Description
Overview
This cable lug is engineered to provide a secure, low-resistance termination for a 70 mm² (or equivalent 70 mm conductor) cable and to interface with equipment via a 10 mm (M10) stud or bolt. It is built from high-conductivity annealed copper and coated with a tin finish to resist oxidation and maintain long-term electrical integrity.
Key Features & Benefits
-
High-purity copper core to ensure excellent conductivity
-
Tin plating for oxidation / corrosion resistance
-
No inspection window (sealed version) in some styles, or optional narrow-palm design (for tight spaces) such as Superlec’s “narrow palm” version. Superlec Direct+1
-
Long barrel style (outdoor type) to allow extra crimps and sealing in harsh environments (as used in CABAC’s “long barrel” version) Cabac
-
Bell-mouth flare entry for easier conductor insertion and reduced damage to strands (common in lugs of this size) EVENTPOWER EQUIPMENT
-
Standards compliance such as AS4325, IEC, DIN / VDE where applicable (CABAC version complies) Cabac
-
Versatile usage: ideal for power distribution, switchgear, battery / ground terminations, industrial systems

Installation / Usage Guidelines
-
Strip insulation to the proper length, ensuring no conductor strands are cut.
-
Insert conductor fully into the lug barrel (if inspection hole exists, use to confirm).
-
Use the proper crimping die / tool for 70 mm lug — apply uniform pressure to form a solid crimp.
-
Secure the lug onto the 10 mm stud / bolt with the correct washer and torque, avoiding overtightening or damaging the lug.
-
Verify mechanical stability and electrical continuity post-installation.
-
In demanding or outdoor environments, inspect periodically for loosening or corrosion, even though tin plating offers protection.
Cautions & Tips
-
Use the correct crimping die — under- or over-crimping degrades performance.
-
Don’t over-torque the M10 bolt — excessive torque may deform the lug or damage conductor.
-
For coupling to dissimilar metals (for example copper lug to aluminum bus), use a transitional or bi-metallic lug variant to prevent galvanic corrosion.
