Reliable Heavy-Duty Copper Cable Terminations for Industrial Power Distribution
Copper tube ring terminals such as the Partex COL185-20 provide a dependable method of connecting large copper conductors to bolted terminals, busbars and industrial power equipment. The tubular barrel accepts a correctly prepared conductor, which is secured using an appropriately sized compression crimping tool and die. When properly installed, the crimped joint provides reliable electrical contact and mechanical retention.
The M20 ring-shaped mounting palm allows the terminated cable to be securely fastened to compatible studs or bolted electrical connection points. Unlike open-ended fork terminals, a closed ring terminal remains captured around the fixing until the nut or bolt is removed, making it particularly useful where connection security and mechanical stability are important. The M20 fixing is especially relevant where the equipment connection incorporates a larger mounting stud.
The COL185-20 is designed for 185 mm² copper conductors used in industrial power distribution, switchgear and heavy-duty electrical machinery. Its copper construction supports efficient electrical conductivity, while the straight terminal configuration provides a conventional connection arrangement for compatible equipment. Because 185 mm² conductors can require substantial installation space, the terminal dimensions, cable bending radius and M20 fixing arrangement must all be suitable for the intended electrical and mechanical requirements.
For correct installation, the terminal should be crimped using tooling and dies appropriate for the terminal and conductor construction. The bolted connection should be tightened to the equipment manufacturer's specified torque. As the COL185-20 is uninsulated, appropriately rated heat-shrink sleeving, insulating boots or protective barriers should be applied where required. The completed termination must be suitable for the circuit current, operating voltage, conductor construction, mechanical loading and environmental conditions. The M20 stud size alone does not establish the current rating of the complete electrical connection.
