Secure 25 mm² Crimp Connections for M8 Electrical Terminals
The Partex PXL25-8 M8 copper tube terminal provides a practical method of connecting 25 mm² copper conductors to stud-mounted electrical equipment. Its tubular barrel is designed to accommodate a correctly prepared conductor, while the bell-mouth entry helps guide the cable into position. The inspection hole allows the installer to confirm that the conductor has been fully inserted before crimping. When compressed using a suitable crimping tool and die, the barrel forms a secure mechanical and electrical connection with the cable.
For reliable installation, electricians should confirm the conductor cross-sectional area, strand construction and stud compatibility before selecting the terminal. Strip the insulation to the appropriate length without damaging the conductor strands, then crimp using the recommended tool and die combination. After crimping, inspect the connection and secure the ring palm to the M8 stud using the equipment manufacturer's specified tightening method. As the PXL25-8 is uninsulated, suitable sleeving, insulation or protective barriers may be required depending on the installation.
Typical Applications
- Industrial electrical control panel manufacturing.
- Termination of 25 mm² copper conductors onto M8 studs.
- Electrical distribution boards and switchgear assemblies.
- Industrial power distribution and equipment connections.
- Motor control centres and industrial automation systems.
- Machinery wiring and manufacturing plant electrical installations.
- Busbar connections and stud-mounted terminal assemblies.
- Commercial electrical infrastructure and maintenance work.
- OEM electrical equipment production and cable assembly.
- Repair and replacement of existing copper ring terminal connections.
