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.

Key Advantages

  • Copper tube butt connector designed for secure end-to-end joining of larger copper power cables.
  • 185 mm² conductor compatibility for suitable copper cable splicing applications.

  • Suitable for permanent electrical cable splicing when correctly installed and protected.
  • Applicable to industrial power distribution, electrical equipment and cable maintenance work.
  • Supplied in packs of 10 pieces.

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.

Typical Applications

  • Industrial copper power cable joining and splicing.
  • Low-voltage electrical power distribution installations.
  • Electrical cable extensions and conductor repairs.
  • Industrial switchgear and distribution equipment wiring.
  • Electrical infrastructure installation and maintenance.
  • Industrial machinery and equipment power connections.
  • Electrical panel manufacturing and refurbishment.
  • Motor control centres and associated power cabling.
  • OEM electrical equipment manufacturing and assembly.
  • Electrical installations requiring end-to-end joining of 185 mm² copper conductors.
  • Cable maintenance projects requiring secure crimped conductor joints.

Frequently Asked Questions

What is the Partex COL185B used for?

The Partex COL185B is used to join two compatible 185 mm² copper conductors end to end using a crimped copper tube connection. It is suitable for electrical cable splicing, extensions and maintenance applications where an in-line conductor joint is required.

What cable size is compatible with the Partex COL185B?

The connector is designed for a nominal conductor cross-sectional area of 185 mm². Both conductors should be checked for compatibility with the connector and the selected crimping equipment before installation.

What is the difference between a butt connector and a ring terminal?

A butt connector joins two electrical conductors directly together, whereas a ring terminal is crimped onto a conductor and secured to an electrical connection point using a threaded stud or bolt. The COL185B is intended for cable-to-cable joining rather than bolted terminal connections.

Can the Partex COL185B be used to extend an electrical power cable?

Yes, the Partex COL185B can be used for suitable cable extension applications involving compatible 185 mm² copper conductors, provided the completed joint is correctly crimped, insulated, mechanically supported and suitable for the electrical and environmental conditions of the installation.

How should the Partex COL185B be installed?

Both 185 mm² copper conductors should be correctly prepared and inserted into opposite ends of the connector. Each side should then be crimped using compatible tooling and the appropriate die according to the applicable installation instructions. The completed joint must be protected with suitable insulation and any additional mechanical or environmental protection required by the installation.

How many connectors are supplied in each pack?

The Partex COL185B is supplied in a pack of 10 copper tube butt connectors, providing a practical quantity for industrial electrical installation, cable maintenance and repair projects.
