Why Choose the Partex PXL150-6 Copper Tube Ring Terminal?
The Partex PXL150-6 is a robust copper tube ring terminal designed for securely terminating 150 mm² copper conductors onto compatible electrical connections using an M6 stud or bolt. Supplied in a convenient pack of 10 terminals, it provides a practical solution for electrical contractors, industrial panel builders, maintenance engineers and equipment manufacturers working with large cross-sectional area copper cables.
Part of the Partex PXL copper tube terminal range, the PXL150-6 features a tubular conductor barrel and a flat ring-type connection palm. The conductor is inserted into the barrel and secured using an appropriately matched crimping tool and die, creating a permanent mechanical and electrical connection when correctly installed. The ring palm is then fastened to a compatible M6 threaded connection point.
The Partex PXL150-6 150 mm² M6 copper cable lug is intended for applications where a large copper conductor must be connected to an appropriately designed M6 terminal point. Its copper construction provides good electrical conductivity, while the ring terminal design offers a retained bolted connection. Because a 150 mm² conductor with an M6 fixing is an unusual combination, installers should carefully verify the equipment's terminal dimensions, contact area, mechanical suitability and electrical rating before installation.

Reliable 150 mm² Copper Cable Terminations
Copper tube ring terminals provide a practical method of connecting electrical conductors to equipment using a crimped cable barrel and a bolted terminal palm. The Partex PXL150-6 is designed for 150 mm² copper cable and an M6 stud connection, allowing a large conductor to be terminated onto a compatible connection point.
The terminal's tubular copper barrel receives the prepared conductor, which is then compressed using an appropriate crimping tool and correctly matched die. When properly crimped, the connection provides mechanical conductor retention and electrical contact between the conductor and terminal barrel.
The ring-type connection palm provides a retained bolted fixing. Unlike an open-ended fork terminal, a ring terminal cannot be removed from the stud without first removing the fastening hardware. This makes ring terminals useful where a mechanically retained connection is required.
For a large conductor such as 150 mm², the correct crimping equipment is particularly important. Suitable hydraulic or other manufacturer-approved crimping equipment may be required to achieve the specified compression. Installers should follow the manufacturer's instructions for conductor preparation, crimp die selection and crimp positioning.
The completed termination must also be mechanically supported where necessary. Large copper cables can impose significant bending forces on electrical connection points, particularly where space is limited. Appropriate cable routing and support help prevent excessive loading on the crimped terminal and equipment stud.
Choosing the Correct 150 mm² M6 Copper Ring Terminal
Selecting a suitable cable lug requires consideration of the conductor cross-sectional area, fixing stud size and equipment connection rating. The Partex PXL150-6 is specified for 150 mm² copper conductors and M6 fixing studs.
Although the terminal is identified as a 150 mm² M6 ring lug, this combination requires particular attention to the electrical equipment's connection design. A large conductor does not automatically make an M6 connection suitable for the conductor's potential current-carrying capacity. The terminal palm, stud, contact surface and complete connection assembly must all be appropriate for the intended load and operating conditions.
The conductor material and construction must also be compatible with the lug. The PXL150-6 is a copper terminal intended for suitable copper conductors. Aluminium conductors and mixed-metal connections require separately specified termination components and installation methods.
As an uninsulated copper ring terminal, the PXL150-6 may require suitable insulating sleeving, heat-shrink tubing or enclosure protection. The terminal's electrical suitability should be established using the manufacturer's technical documentation and the requirements of the completed installation.
Installation Guidance for the Partex PXL150-6
Before installation, confirm that the cable is a compatible 150 mm² copper conductor and that the equipment connection is designed to accept an M6 ring terminal. The available contact area, stud strength, terminal clearance and electrical rating should all be checked.
The conductor should be stripped to the appropriate length using a suitable cable preparation tool. Care must be taken to avoid damaging or removing conductor strands. The prepared conductor should then be inserted fully into the tubular barrel.
A compatible crimping tool and die should be used to compress the terminal barrel in accordance with the manufacturer's recommendations. The completed crimp should be inspected for correct conductor insertion, suitable compression and visible damage.
The ring palm can then be positioned over the M6 connection stud and secured using the equipment manufacturer's specified fixing arrangement. The bolted connection should be tightened to the specified torque rather than an assumed value.
Because the PXL150-6 accommodates a large conductor, suitable cable support should be provided to minimise mechanical stress on the terminal and connection point. The finished installation should be inspected and tested as required by applicable electrical regulations and equipment instructions.
