COL50B Partex copper tube butt connector, 50mm², pack 30

Why Choose the Partex COL50B 50mm² Copper Tube Butt Connector?

The Partex COL50B is a heavy-duty 50 mm² copper tube butt connector designed to provide secure, reliable and durable straight-through electrical connections between copper conductors. Manufactured for professional electrical installations and industrial applications, this uninsulated crimp connector is ideal for joining power cables in electrical distribution systems, industrial machinery, control panels and cable maintenance applications.

As part of the Partex COLB copper tube butt connector range, the COL50B features a robust tubular copper construction designed to support efficient electrical conductivity and dependable mechanical retention when correctly crimped. Its protective tin-plated finish helps resist oxidation and corrosion, while the straight-through barrel design allows two compatible copper conductors to be joined using suitable compression crimping equipment.

Designed for 50 mm² copper cables, the COL50B provides a practical solution for larger conductor connections where reliable electrical continuity and mechanical strength are important. The connector is supplied uninsulated, allowing installers to apply suitable heat-shrink sleeving or other protective insulation according to the installation requirements. Supplied in a convenient pack of 30 connectors, it is suitable for electrical contractors, industrial maintenance engineers, panel builders and power distribution specialists.

Reliable Copper Cable Connections for Industrial Power Distribution

Copper tube butt connectors such as the Partex COL50B provide a dependable method of joining two electrical conductors in a straight-through configuration. Each prepared cable end is inserted into the appropriate side of the tubular connector and secured using a suitable compression crimping tool and die. When correctly installed, the resulting joint provides reliable electrical contact and mechanical retention.

The COL50B is designed for 50 mm² copper conductors used in industrial electrical systems, power distribution equipment and machinery installations. Its copper construction supports efficient current transfer through the connection, while the protective tin-plated surface helps reduce oxidation and corrosion during normal service conditions.

The straight-through connector configuration allows cables to be joined without the need for a separate bolted terminal or mounting stud. This makes copper tube butt connectors particularly useful for inline cable extensions, electrical repairs and permanent conductor splices where a compact connection is required.

For correct installation, conductors should be stripped to the appropriate length without damaging the copper strands, fully inserted into the connector and crimped using suitable tooling. As the COL50B is uninsulated, the completed joint must be provided with appropriately rated insulation and environmental protection where required. The complete cable splice must be suitable for the circuit current, operating voltage, conductor construction and installation conditions.
