Erko Tubular Aluminum Ring Terminal AR 16-300mm

The Erko tubular aluminum ring terminal is a professional-grade connector engineered for the secure termination of aluminum conductors. Designed to accommodate a wide range of cable cross-sections from 16mm² to 300mm², this terminal provides a robust solution for power distribution and electrical infrastructure projects. Its tubular construction ensures a consistent and reliable contact surface, minimizing resistance and maintaining structural integrity under various operational conditions.

Advantages

This terminal offers exceptional mechanical strength and electrical conductivity, which are critical for maintaining stable power flow in aluminum wiring systems. The high-quality aluminum material is specifically selected to prevent galvanic corrosion when properly installed, ensuring long-term durability. Its design facilitates a precise crimping process, which results in a secure connection that withstands thermal expansion and mechanical vibrations common in industrial environments.

Suitable for

• Power distribution cabinets and switchgear
• Industrial electrical installations
• Commercial building power supply systems
• Connecting aluminum conductors to busbars or equipment terminals

When it may not be suitable

This terminal is specifically designed for aluminum conductors and should not be used with copper wiring unless appropriate bimetallic transition methods are applied. It is not intended for use in environments with extreme chemical exposure that could degrade aluminum without proper protective coating.

Key specifications

• Material: High-conductivity aluminum
• Conductor range: 16mm² to 300mm²
• Design: Tubular ring terminal
• Application: Aluminum conductor termination

How to use

To install the terminal, first strip the insulation from the aluminum conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a compatible hydraulic or manual crimping tool with the correct die set corresponding to the conductor size to ensure a proper compression. Ensure the crimping process is performed according to standard electrical installation practices to achieve a gas-tight connection.

What to consider before purchase

• Verify the exact cross-section of your aluminum cable
• Ensure compatibility with your existing crimping tool and die sets
• Confirm the bolt size for the ring terminal hole matches your connection point
• Check for the necessity of jointing compound to prevent oxidation

Usage recommendations

Always use the manufacturer-recommended crimping dies to ensure the integrity of the connection. Regularly inspect the termination point for signs of overheating or mechanical loosening in high-vibration environments.
