## Summary description

The Erko KCZ 6-35 is a professional tubular copper ring terminal designed for reliable electrical connections. Featuring a reduced barrel design, it ensures optimal contact and secure crimping for copper conductors. This durable terminal is ideal for industrial and electrical installation projects requiring high conductivity and mechanical strength in cable termination.

## Long description

The Erko KCZ 6-35 is a professional-grade tubular copper ring terminal engineered for high-performance electrical connections. Designed with a reduced barrel, this terminal facilitates precise crimping and ensures a secure, low-resistance contact for copper conductors. Its robust construction provides the mechanical strength and electrical conductivity necessary for demanding industrial and electrical installation environments.
Advantages
The primary advantage of the Erko KCZ 6-35 lies in its specialized reduced barrel design, which allows for a tighter and more reliable connection compared to standard terminals. Manufactured from high-quality copper, it offers excellent conductivity, minimizing energy loss and heat generation at the connection point. The tubular structure ensures uniform pressure distribution during the crimping process, resulting in a durable termination that resists vibration and mechanical stress over time.
Suitable for
Industrial electrical panel wiring
Power distribution systems
Heavy-duty electrical installations
Grounding connections
When it may not be suitable
This terminal is specifically designed for copper conductors and should not be used with aluminum wiring due to the risk of galvanic corrosion. It is also not intended for high-temperature environments exceeding the thermal limits of standard copper connectors or for applications requiring specialized insulation, as this is a non-insulated terminal.
Key specifications
Material: High-conductivity copper
Terminal type: Tubular ring terminal
Design: Reduced barrel
Conductor compatibility: Copper
How to use
To install the Erko KCZ 6-35, first strip the insulation from the end of the copper conductor to the appropriate length. Insert the conductor fully into the reduced barrel of the terminal. Use a professional-grade crimping tool compatible with tubular copper terminals to apply the necessary pressure, ensuring the barrel is deformed correctly around the wire strands. Verify the integrity of the connection by performing a gentle pull test before securing the ring end to the terminal block or stud using a suitable bolt and nut.
What to consider before purchase
Ensure the terminal size matches the cross-section of your copper conductor.
Verify that your crimping tool is compatible with tubular copper terminals.
Check the stud size of your connection point to ensure the ring hole diameter is appropriate.
Usage recommendations
For optimal performance and safety, always use a calibrated crimping tool and ensure the conductor is clean and free of oxidation before insertion. Avoid reusing terminals once they have been crimped.
