Secure Electrical Connections for Industrial Power Distribution

Copper tube ring terminals are commonly used to terminate electrical conductors where a reliable bolted connection is required. The Partex COL70-14 is designed to connect a 70 mm² copper conductor to an electrical terminal fitted with an M14 stud or compatible fastening.

The tubular copper construction provides a suitable barrel for crimping the conductor, while the ring-shaped connection palm allows the completed termination to be secured beneath a compatible fastening. This arrangement is useful in electrical distribution equipment, industrial control cabinets, switchgear assemblies and machinery where secure cable connections are essential.

For larger conductor sizes such as 70 mm², correct cable preparation and termination are particularly important. The terminal must be matched to the conductor construction and the appropriate crimping system to achieve effective electrical contact and mechanical retention. Suitable cable support also helps minimise stress at the connection point.

During installation, the prepared conductor is inserted into the tubular barrel and secured using an appropriately sized crimping tool and die. A correctly formed crimp provides mechanical retention and effective electrical contact between the conductor and terminal. The ring end is then fastened to the equipment connection point using the specified tightening procedure.

The COL70-14 provides a practical cable termination solution for electrical contractors, panel manufacturers and maintenance personnel. Correct conductor preparation, compatible crimping equipment, appropriate fastening torque and suitable cable support are essential for achieving a dependable electrical connection. The M14 mounting point must also be electrically and mechanically suitable for the intended conductor and load.

Typical Applications

• Electrical distribution boards and switchgear assemblies.
• Industrial control panels and electrical cabinets.
• Electrical equipment terminal connections.
• Compatible busbar and bolted terminal connections.
• Industrial machinery and electrical power connections.
• Power distribution and electrical installation projects.
• Equipment maintenance and cable replacement.
• Panel building and electrical assembly production.
• Commercial and industrial electrical installations.
• Electrical systems requiring 70 mm² conductors with M14 stud connections.
