Why Choose the Partex COL50-8 Copper Tube Ring Terminal?
The Partex COL50-8 is a copper tube ring terminal designed for terminating 50 mm² electrical conductors onto an M8 threaded stud or bolted electrical connection. Supplied in a convenient pack of 50 terminals, this cable lug provides a practical solution for creating secure, mechanically fastened electrical connections in power distribution equipment, industrial control panels 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 M8 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 50 mm² conductor compatibility, M8 stud size and conventional ring terminal configuration, the Partex COL50-8 is suitable for electrical contractors, industrial panel builders and maintenance engineers requiring consistent cable termination solutions. The pack of 50 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 COL50-8 combines a tubular crimp barrel with a closed-ring mounting eye, allowing a correctly prepared 50 mm² conductor to be terminated and mechanically fastened to a compatible M8 electrical connection. The closed-ring configuration provides positive 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, cable 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 and mechanical requirements.
Typical Applications
- Industrial electrical control panels and power distribution assemblies.
- Electrical distribution boards and switchgear installations.
- Power cable connections on electrical equipment.
- Industrial machinery and automation installations.
- Motor control panels and electrical power connections.
- Busbar connections with compatible M8 fastening points.
- Electrical maintenance and cable replacement work.
- Commercial and industrial electrical installations.
- Equipment manufacturing and electrical panel building.
