Reliable Cable Termination for Industrial Electrical Systems

Copper tube ring terminals are widely used in electrical installations to provide secure connections between copper conductors and electrical equipment. By crimping the terminal barrel onto a correctly prepared conductor, installers can create a mechanically robust electrical termination that supports effective current transfer when the terminal is properly selected and installed.

The Partex COL70-12 combines a copper tube barrel with an M12 ring connection, making it suitable for applications requiring a secure bolted cable termination. The ring-shaped palm surrounds the fixing stud, helping retain the terminal at the connection point and providing a practical arrangement for electrical panels, distribution equipment, busbar connections and industrial machinery. Its 70 mm² conductor compatibility makes it particularly relevant to larger cable termination requirements in industrial electrical installations.

For dependable performance, the terminal should be installed using a suitable crimping tool and die matched to the terminal and conductor. The cable should be correctly stripped and fully inserted into the barrel before crimping. The completed ring connection should be secured to a compatible M12 stud using the equipment manufacturer's recommended fastening method and tightening torque. The complete connection must also be assessed for the intended electrical load, conductor construction, cable bending radius and operating environment.
