Why Choose the Partex COL70-16 Copper Tube Ring Terminal?

The Partex COL70-16 is a copper tube ring terminal designed to provide a secure electrical connection between a compatible 70 mm² conductor and an M16 stud or bolted terminal. Suitable for industrial electrical installations, power distribution equipment, switchgear and machinery wiring, this copper crimp lug provides a practical solution for terminating electrical cables onto threaded connection points.

As part of the Partex COL copper tube terminal range, the COL70-16 combines conductive copper construction with a tubular crimp barrel and a closed ring mounting connection. The barrel is designed to accommodate a compatible electrical conductor and be compressed using appropriately selected crimping equipment, while the ring end provides a mounting arrangement for attachment to a suitable M16 stud or bolt. When correctly installed, this arrangement supports electrical continuity and mechanical retention in bolted electrical connections.

Designed for 70 mm² nominal conductor cross-sections and M16 stud connections, the Partex COL70-16 is suitable for electrical assemblies requiring a crimped cable termination and bolted connection arrangement. Supplied in a convenient pack of 50 terminals, it provides a practical solution for electricians, electrical panel builders, OEM equipment manufacturers and industrial maintenance engineers undertaking installation, production and cable termination projects.

Reliable Copper Cable Termination for Industrial Power Distribution

Copper tube ring terminals are used in electrical installations where conductors need to be connected to threaded equipment terminals, busbar connection points and bolted electrical connections. The Partex COL70-16 provides a practical method of terminating a compatible 70 mm² conductor onto an M16 stud. Its closed ring configuration helps maintain the terminal's position beneath the fastening hardware, making it useful for electrical distribution assemblies, industrial machinery, switchgear and equipment installations where a bolted connection is required.

Correct terminal selection and installation are essential for a dependable electrical connection. The conductor should be stripped to the appropriate length, inserted into the copper tube barrel and crimped using a tool and die suitable for the terminal and conductor combination. The ring connection should then be secured to the M16 stud using compatible fastening hardware and the equipment manufacturer's specified tightening torque. The terminal, conductor, stud, contact surface and fastening arrangement must all be verified for the intended electrical current and mechanical loading. Suitable insulation, electrical clearance, cable support, strain relief and bend radius must also be provided. The nominal conductor cross-section and stud size do not, by themselves, establish the current rating of the completed connection.

Typical Applications

  • Industrial electrical power distribution assemblies.
  • Electrical switchgear and control panel manufacturing.
  • Busbar connections incorporating compatible M16 studs.
  • Industrial machinery and electrical equipment wiring.
  • Motor control equipment and power connection assemblies.
  • Electrical cabinets and enclosure installations.
  • OEM electrical equipment manufacturing.
  • Industrial automation and electrical distribution systems.
  • Custom electrical cable assemblies using compatible 70 mm² conductors.
  • Electrical maintenance and cable replacement projects.
  • Bolted equipment connections where the stud and contact arrangement have been verified as suitable.
  • General-purpose electrical termination requiring a 70 mm² crimp barrel and M16 ring mounting connection.
