Why Choose the Partex COL120-20/RA Right-Angle Copper Tube Terminal?
The Partex COL120-20/RA is a robust right-angle copper tube ring terminal designed for secure electrical cable termination in industrial power distribution, switchgear and heavy-duty electrical installations. Suitable for 120 mm² copper conductors and featuring an M20 stud connection, this terminal provides a practical solution for connecting larger electrical cables to compatible equipment terminals, busbars and bolted electrical connections.
Manufactured from copper, the COL120-20/RA offers excellent electrical conductivity and is designed to provide a dependable mechanical and electrical connection when installed using suitable crimping equipment. Its right-angle configuration allows the cable to approach the mounting point at an angle, making it particularly useful where equipment layout, cable routing or installation space makes a straight terminal less convenient.
Designed for 120 mm² electrical cables and M20 mounting studs, the Partex COL120-20/RA is supplied in a convenient pack of 25 terminals. This makes it suitable for electrical contractors, switchgear manufacturers, panel builders and industrial maintenance engineers requiring reliable cable termination components for professional installations.

Secure Right-Angle Connections for Industrial Power Distribution
Right-angle copper tube ring terminals are used to terminate electrical conductors where a secure bolted connection and an angled cable approach are required. The Partex COL120-20/RA is designed to connect a 120 mm² copper conductor to an electrical terminal fitted with an M20 stud or compatible fastening.
The right-angle construction provides an alternative connection arrangement to conventional straight copper tube terminals. This can be particularly beneficial in electrical distribution assemblies, industrial switchgear, control cabinets and machinery where cable routing must accommodate equipment positioning, neighbouring components or restricted installation space.
The terminal's tubular copper barrel provides a suitable connection area for the conductor, while its angled ring palm enables fastening to a compatible bolted terminal. This configuration can help installers manage cable entry direction and equipment connection geometry without introducing unnecessary bending close to the termination.
For larger conductor sizes such as 120 mm², correct cable preparation and termination are especially important. The terminal must be matched to the conductor construction and the appropriate crimping system to achieve effective electrical contact and mechanical retention. Suitable cable support helps minimise mechanical stress at the connection point.
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 effective electrical contact between the conductor and terminal. The ring end is then fastened to the equipment connection point using the specified tightening procedure.
The COL120-20/RA provides a practical cable termination solution for electrical contractors, panel manufacturers and maintenance personnel. Correct conductor preparation, compatible crimping equipment, appropriate fastening torque, suitable cable support and observance of the cable manufacturer's minimum bend radius are essential for a dependable electrical connection. The M20 mounting point must also be electrically and mechanically suitable for the intended conductor and load.
