COL35-16 Partex copper tube ring terminal, 35mm², M16 stud, pack 50

Why Choose the Partex COL35-16 35mm² Copper Tube Ring Terminal?

The Partex COL35-16 is a high-quality 35 mm² copper tube ring terminal designed to provide secure, reliable and durable electrical connections between copper conductors and equipment fitted with M16 stud terminals. Featuring a robust tubular crimp barrel and flat ring-shaped mounting palm, this heavy-duty cable lug is ideal for industrial power distribution, electrical control panels, switchgear assemblies and professional cable termination applications.

As part of the Partex COL copper tube terminal range, the COL35-16 combines high-conductivity copper construction with a protective tin-plated finish to support dependable electrical performance and resistance to oxidation. The tubular barrel is designed for permanent crimp termination using suitable tooling, while the ring-shaped mounting palm provides a secure bolted connection to compatible busbars, terminal studs and electrical equipment.

Designed for 35 mm² copper cables and an M16 mounting stud, the COL35-16 is particularly suitable for industrial and commercial electrical installations requiring secure cable terminations. Its straight terminal configuration enables straightforward cable routing and connection to electrical distribution equipment. Supplied in a convenient pack of 50 terminals, it provides a practical solution for electrical contractors, panel builders, OEM manufacturers and industrial maintenance engineers.

Reliable Copper Cable Terminations for Industrial Power Distribution

Copper tube ring terminals such as the Partex COL35-16 provide a dependable method of connecting electrical conductors to bolted terminals, busbars and industrial power equipment. The tubular barrel accepts a prepared copper conductor, which is secured using an appropriately sized crimping tool and die. When correctly installed, the crimp creates a permanent mechanical connection with reliable electrical contact.

The M16 ring-shaped mounting palm allows the terminated cable to be securely fastened to compatible studs or bolted electrical connection points. Unlike open-ended fork terminals, a ring terminal remains captured around the fixing until the nut or bolt is removed, making it particularly suitable for applications where connection security and mechanical stability are important.

The COL35-16 is designed for 35 mm² copper conductors used in electrical distribution systems, industrial switchgear and machinery. Its high-conductivity copper construction supports efficient electrical current transfer, while the tin-plated finish helps protect the terminal against oxidation and corrosion during normal service conditions.

For correct installation, the terminal should be crimped using suitable tooling and secured using the tightening torque specified for the equipment connection. As the COL35-16 is uninsulated, appropriate heat-shrink sleeving, insulating boots or protective barriers should be applied where required. The completed connection must be suitable for the circuit current, operating voltage, conductor construction and environmental conditions.
