Reliable Copper Cable Termination for Industrial Power Distribution

Copper tube ring terminals provide a dependable method of connecting large electrical conductors to studs, busbars and equipment terminals. The Partex COL300-10 is designed to accommodate 300 mm² copper cable, with a tubular barrel that is compressed around the conductor using an appropriate crimping tool and matching die. Correct compression crimping helps establish a secure connection between the conductor and terminal, supporting effective electrical current transfer and mechanical retention.

Once correctly crimped, the terminal can be fastened to a compatible M10 connection point using suitable fixing hardware. The closed-ring design helps prevent accidental disengagement from the mounting stud, while the copper construction provides excellent electrical conductivity. Its straight configuration makes it suitable for conventional cable routing arrangements in industrial electrical cabinets, power distribution assemblies, switchgear and machinery installations.

For large conductors such as 300 mm² copper cable, careful conductor preparation, correct crimping equipment and appropriate fastening torque are particularly important. The terminal must be selected according to the cable construction, equipment requirements and applicable electrical installation standards. The suitability of the M10 fixing, electrical contact surfaces and associated equipment must also be verified for the intended current, mechanical loading and operating conditions. In particular, a 300 mm² conductor does not automatically establish the current-carrying capability of an M10 bolted connection. The complete termination assembly must be assessed for the intended application.
