COL70-6 Partex copper tube ring terminal, 70mm², M6 stud, pack 50

Why Choose the Partex COL70-6 70mm² Copper Tube Ring Terminal?

The Partex COL70-6 is a heavy-duty 70 mm² copper tube ring terminal designed to provide secure, reliable electrical connections between large cross-section copper conductors and equipment fitted with M6 stud terminals. Featuring a robust tubular crimp barrel and a flat ring-shaped mounting palm, this uninsulated cable lug is suitable for industrial electrical installations, power distribution equipment, machinery and professional cable termination applications.

As part of the Partex COL copper tube terminal range, the COL70-6 combines high-conductivity copper construction with a protective tin-plated finish to support efficient electrical current transfer and resistance to oxidation. The tubular barrel is designed for permanent crimp termination using suitable compression tooling, while the ring-shaped mounting palm provides a secure bolted connection to compatible electrical equipment and terminal studs.

Designed for 70 mm² copper cables and an M6 mounting stud, the COL70-6 provides a specialist termination solution where a large conductor must connect to a comparatively small stud fixing. The terminal and equipment connection must be checked for electrical and mechanical suitability before installation. Supplied in a convenient pack of 50 terminals, it is a practical choice for electrical contractors, panel builders, OEM manufacturers and industrial maintenance engineers.

Reliable Copper Cable Terminations for Industrial Electrical Systems

Copper tube ring terminals such as the Partex COL70-6 provide a practical method of connecting large copper conductors to compatible bolted electrical terminals. The tubular barrel accepts a correctly prepared copper conductor, which is secured using a suitable compression crimping tool and die. When properly installed, the crimped joint provides dependable electrical contact and mechanical retention.

The M6 ring-shaped mounting palm allows the terminated cable to be secured to compatible electrical connection points. Unlike open-ended fork terminals, the closed ring design remains captured around the stud fixing until the fastener is removed, providing additional connection security in appropriately designed electrical assemblies.

The COL70-6 is designed for 70 mm² copper conductors in applications where the equipment requires an M6 fixing. Because the conductor cross-sectional area is relatively large compared with the stud size, installers must ensure that the mounting arrangement, contact surface, terminal geometry and equipment connection are suitable for the intended electrical load. The M6 fixing size alone does not establish the current-carrying capacity of the completed connection.

For correct installation, the terminal should be crimped using the appropriate tooling and secured using the tightening torque specified by the equipment manufacturer. As the COL70-6 is uninsulated, suitable heat-shrink sleeving, insulating boots or protective barriers should be applied where required. The completed termination must be appropriate for the circuit current, operating voltage, conductor construction, mechanical loading and environmental conditions.

Typical Applications

• Industrial electrical control panels and equipment assemblies.
• Specialised power distribution and electrical connection systems.
• Bolted electrical terminals with compatible M6 mounting studs.
• Industrial machinery and automation equipment.
• Electrical equipment manufacturing and panel building.
• Power cable terminations requiring large copper conductors.
• Industrial electrical maintenance and cable replacement.
• Equipment refurbishment and replacement cable connections.
• Custom electrical assemblies requiring secure ring terminal connections.
• Applications requiring 70 mm² copper cable termination onto an appropriately rated M6 stud connection.
