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.
