## Summary description

The Erko KCZ tubular ring terminal is designed for reliable electrical connections of 35mm² copper conductors. Featuring an M8 stud hole, this high-quality copper connector ensures optimal conductivity and mechanical strength. It is ideal for professional electrical installations, switchgear assembly, and power distribution systems where a secure, permanent connection is required.

## Long description

The Erko KCZ copper tubular ring terminal is a professional-grade connector engineered for the secure termination of 35mm² copper conductors. Designed with precision, this terminal features an M8 stud hole, making it compatible with standard electrical hardware. Its tubular construction ensures a robust mechanical bond and excellent electrical conductivity, which is essential for maintaining system integrity in demanding environments.
Advantages
This terminal offers superior performance due to its high-quality copper material, which minimizes resistance and prevents overheating at the connection point. The design facilitates a reliable crimping process, ensuring that the conductor remains firmly in place even under vibration or thermal expansion. Its durable build quality provides long-term stability for critical electrical circuits, reducing the need for frequent maintenance or replacements in power distribution systems.
Suitable for
Electrical switchgear assembly
Power distribution panels
Industrial machinery wiring
Grounding connections
Heavy-duty electrical installations
When it may not be suitable
This terminal is specifically designed for copper conductors and should not be used with aluminum wires due to the risk of galvanic corrosion. It is also not intended for applications requiring high-temperature insulation or specialized environmental sealing beyond standard electrical enclosures.
Key specifications
Conductor cross-section: 35mm²
Stud hole diameter: M8
Material: High-conductivity copper
Connection type: Tubular ring terminal
How to use
To install the terminal, first strip the insulation from the end of the 35mm² copper conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade crimping tool compatible with this specific terminal size to apply uniform pressure, ensuring a gas-tight connection. Once crimped, the terminal can be secured to the M8 stud using a matching nut and washer, ensuring the connection is tightened to the manufacturer's recommended torque specifications.
What to consider before purchase
Verify the conductor cross-section matches the 35mm² specification.
Ensure the M8 stud size is compatible with your existing equipment.
Confirm that you have the correct crimping tool for tubular copper terminals.
Check that the installation environment is free from corrosive elements that could affect copper.
Usage recommendations
Always ensure that the crimping tool is properly calibrated for the terminal size to achieve a secure and permanent electrical connection. Regularly inspect connections in high-vibration environments to ensure they remain tight over time.
