Detailed Description

Overview
This cable lug is designed to terminate a 500 mm² (or equivalent stranded copper) conductor and allow it to be bolted to equipment or busbar via an 18 mm (custom / nonstandard) stud or bolt. It is manufactured from high-purity annealed copper and plated with tin to resist corrosion and maintain reliable electrical contact.

Key Features & Benefits

• High Conductivity Copper: Provides excellent electrical performance.

• Tin Plating: Offers corrosion resistance and durability over long service life.

• Robust Barrel Construction: Engineered to handle mechanical and thermal stresses during crimping and operation.

• Custom Hole Size: 18 mm (nonstandard) stud hole to match special designs or hardware.

• Possible Bell-Mouth / Flared Entry: For easier insertion of strands, depending on design.

• Heavy-Duty Use: Suitable for power distribution systems, switchgear, transformers, large busbars, and industrial equipment.

Specifications

Installation / Usage Guidelines

1. Strip insulation to the correct length, avoiding damage to strands.

2. Insert the bare conductor fully into the lug barrel.

3. Use a crimp tool / die rated for 500 mm² lugs to form a proper, uniform crimp.

4. Bolt the lug onto the 18 mm stud using the correct washer, nut, and recommended torque (avoid over-tightening).

5. After installation, inspect mechanical stability and check electrical continuity.

6. In demanding environments (vibration, moisture, etc.), periodically inspect for loosening or corrosion.

Cautions & Notes

• Because 18 mm stud is nonstandard for 500 mm² lugs, ensure the lug is made or modified to proper tolerances.

• Use the correct crimping dies — undersized or oversized dies reduce reliability.

• Do not exceed safe torque for the 18 mm stud or you risk deforming the lug or damaging the conductor.

• If interface is with dissimilar metals (e.g. aluminum busbars), consider using a bi-metallic or transition lug to prevent galvanic corrosion.
