Reliable Copper Cable Termination for Electrical Installations
Copper tube ring terminals provide a reliable method of connecting electrical conductors to stud-mounted terminals, busbars and electrical equipment. The Partex COL25-12 is designed to accommodate 25 mm² copper cable, with a tubular barrel that is compressed around the conductor using an appropriate crimping tool and die.
Once correctly crimped, the terminal can be secured to a compatible M12 connection point. The closed-ring design helps prevent accidental disengagement from the fixing stud, while the copper construction supports efficient current transfer. Correct cable preparation, crimping and fastening are essential for maintaining connection integrity and minimising electrical resistance.
Typical Applications
- Industrial electrical control panels and switchgear.
- Power distribution boards and busbar connections.
- Electrical machinery and equipment wiring.
- Industrial automation and motor control installations.
- Earthing and bonding connections where appropriately specified.
- Electrical maintenance, repairs and cable replacement.
- OEM panel building and electrical assembly.
