Why Choose the Partex COL120-20 Copper Tube Ring Terminal?
The Partex COL120-20 is a copper tube ring terminal designed for terminating 120 mm² electrical conductors onto an M20 threaded stud or bolted electrical connection. Supplied in a pack of 25 terminals, this copper cable lug provides a practical solution for creating mechanically secure electrical connections in industrial power distribution equipment, switchgear assemblies and electrical installations.
The terminal features a copper tubular crimp barrel and a closed-ring mounting eye. The barrel accommodates a correctly sized electrical conductor for crimp termination, while the M20 ring connection allows the completed cable assembly to be fastened to a compatible threaded stud or bolt. The copper construction provides an electrically conductive connection between the conductor and the equipment termination point.
With its 120 mm² conductor compatibility, M20 stud size and conventional ring terminal configuration, the Partex COL120-20 is suitable for electrical contractors, industrial panel builders and maintenance engineers requiring practical cable termination solutions. The pack of 25 supports electrical equipment manufacturing, installation and maintenance operations.

Reliable Copper Crimp Connections for Industrial Power Distribution
Copper tube ring terminals provide a practical method of connecting electrical conductors to equipment terminals, busbar connection points and threaded studs. The Partex COL120-20 combines a tubular crimp barrel with a closed-ring mounting eye, allowing a correctly prepared 120 mm² conductor to be terminated and mechanically fastened to a compatible M20 electrical connection. The closed-ring configuration provides mechanical retention around the stud while the fastening remains secured.
For dependable installation, the conductor should be prepared and crimped using tooling and dies suitable for the terminal design and conductor size. The completed ring terminal must then be fastened according to the equipment manufacturer's instructions. Correct crimping, conductor selection and fastening are essential for maintaining electrical continuity and reducing the risk of loose or overheated connections. The completed assembly must also be suitable for the intended electrical load, operating conditions, conductor support, cable bending radius and mechanical requirements.
