COL35-10 Partex copper tube ring terminal, 35mm², M10 stud, pack 50

Why Choose the Partex COL35-10 Copper Tube Ring Terminal?

The Partex COL35-10 is a professional 35 mm² copper tube ring terminal designed for terminating electrical conductors onto equipment fitted with an M10 stud or bolt connection. Featuring a tubular copper conductor barrel and ring-shaped fixing end, this terminal provides a practical solution for creating mechanically fastened electrical connections in industrial control panels, power distribution assemblies, electrical machinery and other professional electrical installations.

Designed for use with appropriately sized 35 mm² conductors, the Partex COL35-10 combines a crimp-style cable connection with an M10 ring fixing. The closed ring design allows the terminal to be retained beneath suitable fastening hardware, supporting a secure connection arrangement when correctly crimped and installed. Its copper construction makes it suitable for electrical applications requiring a conductive cable termination component selected to match the conductor and equipment connection.

Supplied in a convenient pack of 50 terminals, the Partex COL35-10 is particularly useful for electrical contractors, control panel manufacturers, OEM machinery builders and industrial maintenance departments carrying out cable termination work. The pack quantity supports efficient component stocking and consistent installation practices across electrical assembly, equipment manufacturing and maintenance projects.

Copper Tube Ring Terminals for Power Distribution and Industrial Electrical Connections

Copper tube ring terminals are commonly used in electrical installations where conductors must be connected to equipment through mechanically fastened electrical connections. The Partex COL35-10 combines a 35 mm² conductor termination with an M10 ring fixing, making it a practical component for compatible electrical control panels, distribution assemblies and industrial machinery. Correctly selected and installed ring terminals help create consistent connections between electrical cables and suitable equipment connection points.

In industrial power distribution and electrical control applications, conductors may need to be connected to terminal studs, equipment connection posts or other bolted connection points. The ring-shaped fixing end provides a closed aperture through which the fastening stud or bolt passes. Unlike an open-ended fork terminal, a ring terminal cannot be lifted away from an intact fastening point without first removing the retaining hardware. This makes ring terminals useful where a securely retained cable connection is required.

The 35 mm² conductor size makes correct cable preparation, terminal selection and crimping particularly important. The conductor should be inserted correctly into the copper tube barrel before crimping with suitable tooling and dies. The completed termination should be inspected for correct conductor insertion, crimp quality and mechanical security. Where required, suitable insulation or protective sleeving should be fitted according to the installation design.

The completed ring connection should be positioned on a compatible M10 stud or bolt and secured using the equipment manufacturer's specified fastening hardware and tightening torque. The conductor cross-section and stud size alone do not establish the permissible current rating or electrical suitability of the complete connection. The equipment terminal rating, conductor construction, contact arrangement, electrical loading and operating conditions must all be verified before installation.

Crimping and Installation Considerations

Correct installation is essential to the electrical and mechanical performance of a copper tube ring terminal. The conductor should be prepared to the appropriate stripping length and inserted into the terminal barrel in accordance with the manufacturer's instructions. Crimping must be carried out using tooling and dies suitable for the terminal and conductor construction.

After crimping, the termination should be checked for correct conductor insertion, crimp positioning and mechanical security. The connection should not exhibit visible damage or evidence of an incorrectly formed crimp. Any required insulation, protective sleeving or additional mechanical protection should be provided as part of the completed electrical installation.

When installing the ring terminal onto an M10 fastening point, the contact surfaces and fastening arrangement should be suitable for the application. The terminal should sit correctly against the intended connection surface and be secured using the equipment manufacturer's specified hardware and tightening torque.

Appropriate cable routing and support should also be considered, especially when working with larger conductors. Excessive bending, pulling or twisting at the crimped connection should be avoided, and the complete installation should be assessed for electrical clearances, vibration, mechanical loading and operating conditions.
