COL185B Partex copper tube butt connector, 185mm², pack 10

Why Choose the Partex COL185B Copper Tube Butt Connector?

The Partex COL185B is a robust copper tube butt connector designed for secure end-to-end joining of electrical cables in industrial power distribution, switchgear and electrical equipment installations. Suitable for 185 mm² copper conductors, this connector provides a practical solution for joining two compatible cables of the same nominal cross-sectional area, creating a continuous electrical connection without requiring a bolted terminal or stud connection.

As part of the Partex COL copper tube connector range, the COL185B offers a dependable solution for electrical cable joining applications requiring effective electrical conductivity and secure mechanical termination. Its copper tube construction supports efficient current transfer, while the butt connector configuration allows compatible copper conductors to be inserted from opposite ends and mechanically crimped to form a secure electrical joint when correctly installed.

Combining a 185 mm² nominal conductor size, a straight butt splice configuration and a convenient pack quantity of 10 connectors, the Partex COL185B is well suited to professional electricians, electrical contractors, panel builders and industrial maintenance teams working with larger copper power cables in distribution assemblies, industrial machinery and electrical infrastructure.

Reliable Cable Joining for Industrial Electrical Systems

Copper tube butt connectors are used in electrical installations to join two compatible copper conductors into a continuous electrical connection. Unlike ring terminals, which connect cables to threaded studs or bolted equipment terminals, butt connectors provide a direct cable-to-cable joining method. This makes them useful for cable extensions, conductor repairs and electrical installation work where a secure in-line connection is required.

The Partex COL185B provides a copper tube connection arrangement suitable for 185 mm² copper conductors. During installation, the prepared cable ends are inserted into opposite sides of the connector and crimped using appropriately selected equipment. When correctly installed, the resulting connection provides mechanical retention and an electrically conductive path between the joined conductors. Its straight configuration is particularly useful where cable alignment and continuity are important.

For dependable performance, both conductors should be correctly stripped and inserted to the required depth before crimping. A suitable crimping tool and die must be selected for the connector and conductor construction, with the required crimp positions and sequence determined by the applicable installation instructions. The completed joint should be provided with appropriate electrical insulation, environmental protection and mechanical support for the installation. The connector should not be treated as insulated or suitable for direct exposure to moisture without an appropriate protective system.
