Why Choose the Partex COL120-12 Copper Tube Ring Terminal?

The Partex COL120-12 is a heavy-duty copper tube ring terminal designed to provide secure and reliable electrical connections for 120 mm² copper conductors. Featuring an M12 stud fixing, this crimp cable lug is suitable for industrial power distribution, electrical switchgear, control panels and heavy-duty electrical installations where dependable cable termination is essential.

As part of the Partex COL copper tube terminal range, the COL120-12 combines a robust copper tubular barrel with a flat ring-type fixing palm. Its conductive copper construction supports efficient electrical current transfer, while the crimp termination design enables a mechanically secure connection when installed using appropriately sized crimping equipment.

Designed for 120 mm² copper cables and M12 bolted connections, the COL120-12 is particularly suitable for power distribution assemblies, industrial machinery, motor control centres and electrical cabinets. Its straight terminal configuration provides a practical solution for connecting large copper conductors to compatible equipment terminals and busbars. Supplied in a pack of 25 terminals, it is ideal for electrical contractors, panel builders, industrial maintenance engineers and OEM equipment manufacturers.

Reliable Heavy-Duty Cable Termination for Industrial Power Systems

Copper tube ring terminals are designed to establish secure electrical connections between copper conductors and equipment connection points. The Partex COL120-12 features a tubular crimp barrel for a 120 mm² copper conductor and a flat ring palm with an M12 fixing hole. This arrangement allows large power cables to be securely connected to compatible studs, busbars and electrical equipment terminals.

The terminal's copper construction provides an effective conductive path when correctly crimped and installed. Its straight configuration is particularly useful in distribution boards, switchgear assemblies, motor control centres and industrial electrical cabinets where a conventional ring-type cable termination is required.

For dependable electrical and mechanical performance, the COL120-12 should be installed using a crimping tool and die specifically suitable for 120 mm² copper tube terminals. The conductor must be correctly prepared and fully inserted before crimping. The M12 fixing should then be secured using appropriate hardware and the tightening torque specified by the connected equipment manufacturer. The completed connection must be insulated or otherwise protected as required by the installation and operating environment.

Typical Applications

  • Industrial power distribution boards and switchgear assemblies.
  • Heavy-duty electrical control panels and distribution cabinets.
  • Busbar connections and electrical equipment terminals.
  • Motor control centres and industrial motor power connections.
  • Industrial machinery and manufacturing equipment.
  • Electrical panel manufacturing and OEM equipment assembly.
  • Large copper power cable termination.
  • Industrial electrical maintenance and cable replacement.
  • Power distribution installations requiring 120 mm² copper conductors.
  • Bolted electrical connections to compatible M12 fixing points.

Frequently Asked Questions

What is the Partex COL120-12 used for?

The Partex COL120-12 is a copper tube ring terminal used to connect 120 mm² copper conductors to electrical equipment with M12 stud connections. It is suitable for industrial power distribution, switchgear, control panels and heavy-duty electrical installations.

What cable size is compatible with the COL120-12?

The terminal is designed for 120 mm² copper conductors. The conductor must be compatible with the terminal barrel and installed using an appropriately sized crimping tool and die.

What stud size does this copper tube ring terminal fit?

The COL120-12 is designed for an M12 stud or bolt connection, allowing it to be secured to compatible electrical equipment terminals, busbars and connection points.

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

A ring terminal connects a cable to an equipment terminal, stud or busbar using a bolted fixing, whereas a butt connector joins two cable ends directly. The COL120-12 is designed for bolted electrical termination rather than cable-to-cable splicing.

What material is the COL120-12 manufactured from?

The terminal is manufactured from copper, providing good electrical conductivity for heavy-duty industrial power cable termination.

Does the Partex COL120-12 require crimping?

Yes. The terminal is designed for mechanical crimping onto a 120 mm² copper conductor. A compatible crimping tool and correctly matched die should be used to create a secure electrical and mechanical connection.

How many terminals are supplied in a pack?

The Partex COL120-12 is supplied in a pack of 25 copper tube ring terminals, suitable for electrical installation, panel manufacturing and industrial maintenance applications.
