PXL630-16 Partex PXL copper tube ring terminal, 630mm², M16 stud, pack 1

Why Choose the Partex PXL630-16 Copper Tube Ring Terminal?

The Partex PXL630-16 is a heavy-duty copper tube ring terminal designed for secure electrical termination of very large cross-section copper conductors. Suitable for 630 mm² copper cables and featuring an M16 stud connection, this crimp cable lug provides a practical connection solution for high-capacity industrial power distribution systems, electrical switchgear, busbar assemblies and heavy-duty electrical infrastructure.

As part of the Partex PXL copper tube terminal range, the PXL630-16 combines a substantial tubular conductor barrel with a closed-ring mounting palm. The barrel accommodates a correctly prepared copper conductor and is designed to form a secure mechanical and electrical connection when compressed using suitable crimping equipment. The ring-shaped palm allows the completed cable termination to be fastened to a compatible threaded stud or bolted electrical connection point.

Supplied as a pack of 1 terminal, the Partex PXL630-16 is suitable for specialist electrical contractors, industrial maintenance engineers, switchgear manufacturers and power distribution professionals working with large power cables. Its combination of 630 mm² conductor compatibility and an M16 mounting connection makes it particularly relevant to installations requiring substantial copper conductors to be terminated at compatible bolted connection points.

Secure Crimp Termination for Very Large Industrial Power Cables

Copper tube ring terminals are used to connect electrical conductors to power distribution equipment, busbars, switchgear and other bolted electrical connection points. The conductor is prepared, inserted into the terminal barrel and compressed using a compatible crimping tool and die. When the terminal, conductor and tooling are correctly matched, the crimping process produces a mechanically secure connection with effective electrical contact.

The Partex PXL630-16 is designed for 630 mm² copper conductors requiring an M16 mounting connection. Its closed-ring palm provides a defined bolted connection point, helping retain the terminal while the fixing hardware remains secured. This combination is relevant to specialist industrial electrical assemblies where very large conductors must be connected to compatible equipment terminals.

At a conductor size of 630 mm², cable preparation, conductor construction and crimping compatibility are particularly important. Installers should verify the cable's strand configuration, the terminal barrel dimensions and the correct crimping die or compression profile before beginning work. Suitable heavy-duty hydraulic or other manufacturer-approved crimping equipment may be necessary to achieve the required compression.

The completed crimp should be inspected in accordance with the relevant installation instructions before the ring terminal is secured to the M16 connection point. The equipment manufacturer's specified tightening procedure must be followed, and suitable electrical insulation or protective covers should be applied where required. The current-carrying capacity and thermal performance of the complete connection must be assessed for the installation; conductor size alone does not establish the rating of the finished joint.
