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.
