## Long description

The Erko ARC 8-70/1 is a professional-grade tubular aluminum ring terminal specifically engineered for the reliable termination of 70mm² aluminum conductors. This component is designed to facilitate a secure and stable electrical connection within power distribution systems, ensuring optimal performance in demanding industrial and commercial environments. Its robust tubular design is crafted to provide excellent electrical conductivity and long-term mechanical durability, making it a dependable choice for electrical infrastructure projects.
Advantages
The primary advantage of this aluminum ring terminal lies in its specialized tubular construction, which allows for a high-integrity connection that minimizes resistance and prevents overheating. The material composition is optimized for aluminum conductors, ensuring compatibility and preventing galvanic corrosion when installed correctly. Its precise manufacturing ensures a consistent fit for 70mm² cables, while the 8mm mounting hole provides versatility for attachment to various busbars, studs, or terminal blocks commonly found in electrical panels and switchgear.
Suitable for
Termination of 70mm² aluminum power cables
Industrial power distribution cabinets
Commercial electrical installations
Connection to busbars or threaded studs
This terminal is not suitable for use with copper conductors due to the risk of galvanic corrosion between dissimilar metals unless appropriate bimetallic transition methods are employed. It is also not intended for applications requiring extreme vibration resistance without additional strain relief measures or for environments where the terminal material is exposed to highly corrosive chemical agents.
Key specifications
Conductor cross-section: 70mm²
Material: Aluminum
Mounting hole diameter: 8mm
Terminal type: Tubular ring terminal
To use the Erko ARC 8-70/1, first strip the insulation from the 70mm² aluminum conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade hydraulic or mechanical crimping tool specifically calibrated for aluminum tubular terminals to ensure a gas-tight connection. Ensure that the crimping process follows the manufacturer's guidelines for the specific tool and die set to achieve the required compression force.
What to consider before purchase
Verify the conductor cross-section matches the 70mm² specification
Ensure the 8mm mounting hole is compatible with your existing hardware
Confirm the use of appropriate crimping tools for aluminum terminals
Check environmental conditions to ensure aluminum is suitable for the installation site
Usage recommendations: Always apply an appropriate contact grease or joint compound designed for aluminum electrical connections before crimping to prevent oxidation and ensure long-term electrical stability. Ensure the connection point is clean and free of debris before installation.
