Secure Electrical Connections for Industrial Power Distribution

Copper tube ring terminals are commonly used to terminate electrical conductors where a secure bolted connection is required. The Partex COL300-16 is designed to connect a 300 mm² copper conductor to an electrical terminal fitted with an M16 stud or compatible fastening.

The tubular copper construction provides a suitable barrel for crimping the conductor, while the ring-shaped connection palm allows the completed termination to be secured beneath a compatible fastening. This arrangement is useful in industrial electrical distribution equipment, switchgear assemblies, power panels and machinery where dependable cable connections are essential.

For larger conductor sizes such as 300 mm², correct cable preparation and termination are especially important. The terminal must be matched to the conductor construction and an appropriate crimping system to achieve effective electrical contact and mechanical retention. Suitable cable support also helps minimise stress at the connection point.

During installation, the conductor is stripped to the appropriate length without damaging its strands. The prepared conductor is inserted into the tubular barrel and secured using a compatible crimping tool and die, following the recommended crimping procedure. A correctly formed crimp provides mechanical retention and effective electrical contact between the conductor and terminal.

Once crimped, the ring palm is positioned over the compatible M16 stud and secured using the equipment manufacturer's specified fastening arrangement and tightening procedure. Appropriate contact surface preparation, electrical clearance and cable support should be considered during installation.

The 300 mm² conductor and M16 stud combination requires particular attention to the electrical and mechanical suitability of the equipment connection. The conductor size alone does not determine the current-carrying capacity of the complete connection; the terminal, fastening arrangement, contact surface, equipment rating and installation conditions must all be suitable for the intended application.

The COL300-16 provides a practical cable termination solution for electrical contractors, switchgear manufacturers and industrial maintenance personnel. Correct conductor preparation, compatible crimping equipment, appropriate fastening torque, suitable cable support and adequate installation clearance are essential for achieving a dependable electrical connection.
