Why Choose the Partex PXL150-8 Copper Tube Ring Terminal?
The Partex PXL150-8 is a heavy-duty copper tube ring terminal designed for terminating compatible 150 mm² copper conductors onto electrical connection points using an M8 stud or bolt. Supplied in a convenient pack of 10 terminals, it offers a practical cable termination 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 PXL150-8 combines a tubular conductor barrel with a flat ring-type connection palm. The conductor is inserted into the barrel and secured using a correctly matched crimping tool and die, producing a permanent mechanical and electrical connection when properly installed. The ring palm is then fastened to a compatible M8 threaded connection point using the appropriate fixing hardware.
The Partex PXL150-8 150 mm² M8 copper cable lug is suitable for consideration in industrial electrical equipment, power distribution assemblies, machinery and specialist electrical installations where a large copper conductor must be connected to an appropriately designed M8 terminal. Its copper construction provides good electrical conductivity, while the ring design offers a retained bolted connection. Because the conductor size is substantial relative to the M8 fixing, the equipment connection's electrical rating, contact area and mechanical suitability must be verified before installation.

Reliable 150 mm² Copper Cable Terminations for Industrial Equipment
Copper tube ring terminals are widely used where an electrical conductor must be connected to equipment through a secure crimped and bolted termination. The Partex PXL150-8 is designed to accommodate a 150 mm² copper conductor and provide an M8 ring connection, making it a specialist option for installations where the receiving terminal is appropriately designed for this combination.
The terminal's tubular copper barrel receives the prepared conductor. A suitable crimping tool compresses the barrel around the conductor using the correct die profile and compression method. When the terminal and tooling are properly matched, this process creates mechanical retention and establishes electrical contact between the conductor and the copper barrel.
The ring-type connection palm provides a retained bolted fixing. Unlike an open-ended fork terminal, a ring terminal cannot be lifted away from the stud without removing the fastening hardware. This design is useful in electrical assemblies where a secure and mechanically retained connection is required.
For a conductor as large as 150 mm², correct crimping equipment is particularly important. Depending on the manufacturer's requirements, suitable hydraulic or other approved compression tooling may be necessary. The installer must verify the correct die, crimping sequence, conductor insertion depth and number of crimps rather than assuming that any tool rated for 150 mm² cable will be suitable.
The completed connection should also be protected against excessive mechanical stress. Large copper conductors can exert significant forces on equipment terminals, particularly where cables are bent tightly or unsupported. Appropriate cable routing, bending clearance and support help reduce the risk of movement or loading at the termination.
Choosing the Correct 150 mm² M8 Copper Ring Terminal
Selecting the correct cable lug involves more than matching the conductor cross-sectional area. The Partex PXL150-8 is identified for 150 mm² copper cable and an M8 fixing stud, but the conductor construction, terminal barrel dimensions, connection palm and equipment requirements must also be considered.
Different ring terminals can accommodate the same conductor size while using different stud diameters. For example, the Partex PXL150-6 is intended for an M6 fixing, while the PXL150-8 uses an M8 connection. The correct stud size helps ensure that the ring palm can be fitted securely, but it does not by itself establish the electrical or mechanical suitability of the completed connection.
Because 150 mm² is a large conductor cross-sectional area, an M8 stud must be assessed carefully for the intended application. The equipment terminal, stud, contact surface, fixing hardware and cable lug must be capable of supporting the expected electrical load and mechanical forces. The current-carrying capacity of the conductor must not be treated as proof that the M8 bolted connection is suitable for the same current.
The PXL150-8 is a copper terminal intended for compatible copper conductors. Aluminium conductors and mixed-metal electrical connections require appropriately specified termination components. Where the installation requires electrical insulation, suitable sleeving, heat-shrink tubing or enclosure protection should be provided.
Installation Guidance for the Partex PXL150-8
Before installation, confirm that the cable is a compatible 150 mm² copper conductor and that the equipment connection is designed to accept an M8 ring terminal. The terminal's contact area, equipment electrical rating, fixing hardware and available installation clearance should all be checked.
The conductor should be stripped to the correct length using an appropriate cable preparation tool. Care should be taken to avoid damaging or removing conductor strands. The stripped conductor must be inserted fully into the terminal barrel before crimping.
Use a crimping tool and die specifically suitable for the terminal and conductor combination. Follow the manufacturer's recommended crimping procedure, including the correct crimp position and any required multiple compressions. After crimping, inspect the termination for correct conductor insertion, complete compression and visible damage.
The ring palm should then be positioned over the M8 stud and secured using the specified fixing arrangement. The connection must be tightened to the torque recommended by the equipment manufacturer. Excessive tightening can damage the stud or terminal, while insufficient tightening may compromise the electrical connection.
Suitable cable support should be provided to minimise mechanical loading on the termination. The completed assembly should be inspected and tested as required by the applicable electrical installation standards, equipment instructions and project specifications.
