Secure Electrical Connections for Industrial Wiring
Copper tube ring terminals are widely used to terminate electrical conductors where a reliable bolted connection is required. The Partex COL6-4 is designed to connect a 6 mm² copper conductor to an electrical terminal fitted with an M4 stud or compatible fastening.
During installation, the prepared conductor is inserted into the tubular barrel and secured using an appropriately sized crimping tool and die. A correctly formed crimp provides mechanical retention and electrical contact between the conductor and terminal. The ring end can then be fastened to the equipment connection point using the specified tightening procedure.
The COL6-4 is a practical choice for electrical contractors, panel manufacturers and maintenance personnel who require repeatable cable terminations. Correct conductor preparation, crimping equipment selection and fastening torque are essential for achieving a dependable connection.
