PXL500-20 Partex PXL copper tube ring terminal, 500mm², M20 stud, pack 1

Why Choose the Partex PXL500-20 Copper Tube Ring Terminal?

The Partex PXL500-20 is a heavy-duty copper tube ring terminal designed for secure termination of large copper power cables in industrial electrical distribution systems, switchgear assemblies and high-capacity electrical installations. Part of the Partex PXL copper tube terminal range, this cable lug provides a practical solution for connecting substantial copper conductors to compatible bolted electrical terminals where dependable mechanical retention and electrical continuity are essential.

Designed for 500 mm² copper conductors, the PXL500-20 combines a tubular compression crimp barrel with a closed-ring connection palm featuring an M20 stud fixing. Its copper construction provides excellent electrical conductivity, while the compression crimp design enables a secure mechanical and electrical connection when installed using an appropriately selected heavy-duty crimping tool and matching die.

Supplied as a single terminal (pack of 1), the Partex PXL500-20 is suitable for specialist electrical installation, industrial maintenance and large power cable termination projects. Its combination of a 500 mm² nominal conductor size and M20 ring connection makes it particularly useful for terminating large copper cables onto compatible busbars, power distribution equipment, industrial switchgear and electrical power terminals.

Reliable Compression Crimp Connections for Large-Section Power Cables

Large copper power conductors require correctly selected termination components to establish secure electrical connections within power distribution equipment. The Partex PXL500-20 provides a tubular copper barrel designed for terminating 500 mm² copper conductors, supporting a mechanically secure and electrically conductive connection when installed using the appropriate compression crimping procedure.

During installation, the conductor insulation should be stripped to the correct length without damaging the copper strands. The prepared conductor is inserted fully into the terminal barrel before a suitably rated compression crimping tool and matching die are used to form the connection. For a conductor of this size, correct tool selection, crimp positioning, conductor compatibility and adherence to the terminal manufacturer's installation instructions are particularly important. The completed crimp should be inspected to confirm that the termination has been formed correctly.

The M20 ring connection enables the terminated cable to be secured to compatible threaded studs, busbar connection points and heavy-duty electrical equipment terminals. Its closed-ring palm provides mechanical retention beneath the fixing hardware, making it suitable for industrial electrical assemblies where dependable bolted connections are essential. Appropriate contact surface preparation, connection hardware and manufacturer-specified tightening torque help maintain electrical continuity and connection integrity throughout service.
