Reliable Inline Cable Connections for Industrial Electrical Installations

Copper tube butt connectors are used to join electrical conductors where a secure inline connection is required. The Partex COL25B is designed for connecting compatible 25 mm² copper conductors, making it a practical choice for electrical installations, cable extensions and maintenance work.

Unlike ring terminals, which connect conductors to studs or bolted terminals, butt connectors provide a direct conductor-to-conductor connection. The tubular construction allows prepared cable ends to be inserted into opposite sides of the connector, creating an inline joint that can be secured through the appropriate crimping process.

During installation, the conductor insulation is stripped to the required length and each prepared conductor is inserted into its respective end of the connector. A compatible crimping tool and correctly sized die are then used to secure the conductors. Properly formed crimps provide mechanical retention and effective electrical contact within the joint.

The COL25B offers a practical cable joining solution for electrical contractors, panel manufacturers and maintenance personnel. Correct conductor preparation, compatible crimping equipment and suitable insulation or joint protection are essential for achieving a dependable connection. Any required electrical insulation, environmental sealing or mechanical protection must be provided as part of the completed installation.

Typical Applications

• Electrical cable extensions and inline conductor joining.
• Industrial electrical distribution systems.
• Electrical control panels and power distribution cabinets.
• Machinery wiring and industrial equipment connections.
• Electrical installation and cable maintenance projects.
• Repair and replacement of compatible copper conductors.
• Panel building and electrical assembly production.
• Commercial and industrial electrical installations.
• Electrical wiring requiring secure 25 mm² conductor splices.
• Maintenance workshops and electrical contracting applications.
