COL35B Partex copper tube butt connector, 35mm², pack 50

Why Choose the Partex COL35B Copper Tube Butt Connector?

The Partex COL35B is a copper tube butt connector designed to join two compatible 35 mm² electrical conductors in a secure inline connection. Suitable for industrial electrical installations, control panels, distribution equipment and machinery wiring, this copper crimp connector provides a practical solution for joining cables without requiring a separate terminal block or stud connection.

As part of the Partex COL copper tube terminal and connector range, the COL35B features a tubular copper construction designed for crimp termination. Conductors are inserted from opposite ends of the connector and secured using appropriately selected crimping equipment. The copper construction provides excellent electrical conductivity, while correctly formed crimps establish the mechanical retention and electrical continuity required for dependable conductor joining.

Designed for 35 mm² nominal conductor cross-sections, the Partex COL35B is suitable for cable assembly, conductor joining and electrical maintenance applications where an inline cable connection is required. Supplied in a convenient pack of 50 connectors, it is particularly useful for electrical contractors, panel builders, OEM equipment manufacturers and industrial maintenance engineers undertaking repeated cable termination and wiring projects.

Reliable Inline Cable Joining for Industrial Electrical Installations

Copper tube butt connectors are used in electrical installations where two conductors need to be joined to form a continuous electrical connection. The Partex COL35B provides a practical method of joining compatible 35 mm² conductors using a crimped copper tube connection. Unlike ring terminals, which connect conductors to threaded studs or equipment terminals, butt connectors are designed for conductor-to-conductor connections, making them useful for cable assembly, electrical maintenance and wiring modifications.

Correct installation is essential to achieving a dependable electrical joint. Both conductors should be prepared to the appropriate stripping length, inserted into the connector and secured using a crimping tool and die suitable for the connector and conductor combination. The completed joint must be provided with appropriate electrical insulation, mechanical protection and strain relief where required. Conductor compatibility, current-carrying requirements, joint location, installation conditions and applicable electrical standards must also be considered. The conductor cross-section alone does not establish the current rating of the completed connection.

Typical Applications

• Inline joining of compatible 35 mm² electrical conductors.
• Industrial electrical control panel wiring.
• Electrical distribution equipment and cable assemblies.
• Electrical cabinet and enclosure assembly.
• Industrial machinery and equipment wiring.
• OEM electrical cable assembly manufacturing.
• Motor control and industrial automation equipment.
• Electrical cable maintenance and replacement work.
• Industrial equipment refurbishment and wiring modifications.
• Building services electrical installations where suitable cable joints are permitted.
• General-purpose conductor splicing using compatible crimping equipment.
