COL120B Partex copper tube butt connector, 120mm², pack 20

Why Choose the Partex COL120B Copper Tube Butt Connector?

The Partex COL120B is a robust copper tube butt connector designed for joining electrical conductors in industrial, commercial and power distribution applications. Suitable for 120 mm² copper conductors, this connector provides a practical solution for creating secure in-line cable connections using a suitable crimping system.

Manufactured from copper, the COL120B offers excellent electrical conductivity and is designed to establish a dependable electrical and mechanical connection when correctly crimped. Its tubular construction allows prepared cable ends to be inserted from opposite sides, enabling two compatible conductors to be joined in a continuous cable run without requiring a stud, bolt or ring terminal connection.

Designed for 120 mm² electrical cables, the Partex COL120B is supplied in a convenient pack of 20 butt connectors. It is suitable for electrical contractors, panel builders, industrial maintenance engineers and cable installation professionals requiring reliable crimp splice components for larger copper conductors.

Secure In-Line Cable Connections for Industrial Electrical Installations

Copper tube butt connectors are commonly used to join two electrical conductors where a continuous cable connection is required. The Partex COL120B is designed for creating an in-line crimp splice between compatible 120 mm² copper conductors, making it suitable for cable extensions, repairs and industrial electrical installations.

Unlike a copper tube ring terminal, which connects a conductor to a stud or bolted terminal, a butt connector joins conductors directly. The prepared cable ends are inserted into opposite sides of the tubular connector and secured using an appropriate crimping tool and die. This produces a permanent electrical connection when the connector, conductor and crimping system are correctly matched.

For larger conductor sizes such as 120 mm², correct cable preparation and crimping are particularly important. The conductors should be stripped to the appropriate length without damaging the strands, and the connector should be crimped using equipment suitable for its dimensions and conductor construction.

The completed joint must be insulated and protected using a suitable cable jointing method appropriate to the installation environment, operating voltage and applicable electrical requirements. Heat-shrink insulation, joint enclosures or other approved insulation systems may be required depending on the application.

The COL120B provides a practical solution for electrical contractors, maintenance personnel and industrial installers working with larger copper cables. Correct conductor compatibility, crimping technique, electrical insulation, cable support and mechanical protection are essential for achieving a dependable and safe electrical connection.

Typical Applications

• Industrial electrical cable extensions.
• Joining compatible 120 mm² copper conductors.
• Electrical cable repair and replacement projects.
• Industrial power distribution wiring.
• Electrical infrastructure installation and maintenance.
• Industrial machinery power cable connections.
• Electrical panel and equipment wiring assemblies.
• Commercial and industrial electrical installations.
• Cable jointing applications requiring an in-line crimp connection.
• Maintenance of electrical systems using larger copper conductors.
