Why Choose the Partex COL16-8 16mm² Copper Tube Ring Terminal?

The Partex COL16-8 is a high-quality 16 mm² copper tube ring terminal designed to provide secure, reliable and durable electrical connections between copper conductors and equipment fitted with M8 stud terminals. Its robust tubular crimp barrel and flat ring-shaped mounting palm make it an ideal solution for electrical distribution systems, industrial control panels, machinery wiring and professional cable termination applications.

As part of the Partex COL copper tube terminal range, the COL16-8 combines conductive copper construction with a protective tin-plated finish to support dependable electrical performance and resistance to oxidation. The tubular barrel is designed for permanent crimp termination, while the ring-shaped palm provides a secure bolted connection to compatible electrical equipment.

Designed for 16 mm² copper cables and an M8 mounting stud, the COL16-8 is suitable for a wide range of industrial and commercial electrical installations. Its straight terminal configuration allows straightforward cable routing to busbars, terminal studs and electrical connection points. Supplied in a convenient pack of 100 terminals, it provides a practical solution for electrical contractors, panel builders, OEM manufacturers and maintenance engineers.

Reliable Copper Cable Terminations for Industrial Electrical Systems

Copper tube ring terminals such as the Partex COL16-8 provide a dependable method of connecting electrical conductors to bolted terminals, busbars and electrical equipment. The tubular barrel accepts a prepared copper conductor, which is secured using an appropriately sized crimping tool and die. This creates a permanent mechanical connection with reliable electrical contact when installed correctly.

The M8 ring-shaped mounting palm allows the terminated cable to be fastened to compatible studs or bolted electrical connection points. Unlike open-ended fork terminals, a ring terminal remains captured around the fixing until the nut or bolt is removed, making it particularly suitable for applications where connection security is important.

The COL16-8 is designed for use with 16 mm² copper conductors in electrical distribution, machinery and industrial control applications. Its copper construction supports efficient electrical conductivity, while the tin-plated surface helps protect the terminal against oxidation during service.

For correct installation, the terminal must be crimped using suitable tooling and secured with the tightening torque specified for the equipment connection. As the COL16-8 is uninsulated, suitable heat-shrink sleeving, insulating boots or protective barriers should be applied where required. The complete connection must be appropriately rated for the circuit current, voltage, conductor construction and installation environment.

Typical Applications

  • Industrial electrical control panels and switchgear assemblies.
  • Electrical distribution boards and power distribution equipment.
  • Busbar connections and bolted electrical terminals.
  • Industrial machinery and automation systems.
  • Motor control centres and associated electrical equipment.
  • OEM electrical equipment manufacturing and panel building.
  • Power cable termination and electrical equipment connections.
  • Commercial and industrial electrical installations.
  • Electrical maintenance, cable replacement and equipment refurbishment.
  • Electrical systems requiring secure 16 mm² copper cable connections to M8 studs.
