Detailed Description
Overview
This cable lug is engineered to terminate a 400 mm² (or equivalent) copper conductor and connect it securely to a 16 mm (M16) stud or bolt. Constructed from high-conductivity annealed copper and coated with tin plating, it ensures low resistance, long-term stability, and resistance to corrosion.
Key Features & Benefits
-
High Conductivity Copper Core: Ensures minimal voltage drop and efficient current flow.
-
Tin Plating: Provides oxidation / corrosion protection for long service life.
-
Solid Barrel / Seamless Construction: Offers mechanical strength and uniform compression.
-
Flared / Bell Mouth Entry: Helps guide stranded cable into the lug and reduce strand damage.
-
Option for Inspection / Window Hole (in some designs): Allows visual confirmation that all conductors are properly seated.
-
Standard Compliance: Many 400 mm² lugs (like Cembre A80 series) support stud holes including M16.
-
Application Versatility: Ideal for power distribution, switchgear terminations, busbars, grounding systems, industrial connections.
Specifications
| Parameter | Value / Typical |
|---|---|
| Conductor / Cable Size | 400 mm² (stranded copper) |
| Mounting Hole / Stud | 16 mm (M16) |
| Material | Annealed copper (≥ 99.9 %) |
| Finish / Coating | Tin plated (electro-tin) |
| Entry / Barrel Design | Bell / flared mouth (typical for large lugs) |
| Inspection Feature | May include inspection hole in some variants |
| Dimensions (example for Cembre A80 series) | Cembre’s 400 mm² lugs are made with stud hole options including M16. |
| Rated Use | Low voltage / power distribution systems (e.g. 600/1000 V class typical) |
Installation / Usage Guidelines
-
Strip insulation carefully to the required length, without severing cable strands.
-
Fully insert the conductor into the lug barrel; if inspection hole exists, confirm insertion visually.
-
Use a proper crimping die / tool rated for 400 mm² copper lugs and apply uniform compression.
-
Fasten the lug onto the 16 mm stud / bolt using proper washer and torque (do not over-tighten).
-
After installation, inspect the joint for mechanical security, continuity, and ensure no stray strands.
-
In outdoor or high-vibration environments, inspect periodically for signs of loosening or corrosion even though tin plating offers protection.
Cautions & Tips
-
Always use the correct crimp die / tool for 400 mm² lugs — using too small or wrong tooling will compromise the connection.
-
Avoid exceeding torque limits on M16 stud — over-torquing can deform the lug or cable.
-
If connecting to dissimilar metals (e.g. copper lug to aluminum bus), consider using a bi-metal or transition lug to reduce galvanic corrosion.
