## Long description

Radpol CU-CYN. 25 FI10 KOS copper ring terminal is a crimp/press connector engineered for 25 mm² conductors with a 10 mm inner ring diameter. Manufactured from copper to provide consistent electrical conductivity and enhanced resistance to corrosion, this ring connector is intended for bolted connections to studs, busbars and grounding points in electrical installations and switchgear. The design supports reliable mechanical and electrical contact in industrial, commercial and residential wiring contexts.
Advantages
The copper construction ensures low contact resistance and stable conductivity over time while offering natural corrosion resistance. The terminal’s ring form and specified inner diameter provide a secure fit on 10 mm studs, reducing the risk of loosening under vibration. The product is suitable for crimping or pressing with compatible tools, yielding a compact, mechanically robust joint that simplifies termination and inspection of 25 mm² cables.
Suitable for
Bolted connections to studs and busbars in switchgear and distribution panels
Grounding and earthing connections in electrical installations
Terminating 25 mm² copper conductors in industrial and commercial equipment
Electrical maintenance and retrofit work requiring secure ring terminals
Key specifications
Conductor cross-section: for 25 mm² cable
Material: copper
Connection type: crimp/press ring terminal
Inner ring diameter: 10 mm
Suitable for bolted/stud connections and busbar terminations
How to use
Strip the insulation from the conductor to the appropriate length, insert the exposed conductor fully into the barrel of the ring terminal, and perform crimping or pressing with a compatible crimping/pressing tool sized for 25 mm² terminals. Ensure the crimp is secure and inspect for stray strands. Mount the terminal onto the 10 mm stud or bolt and tighten the fastening to the torque recommended for the installation; use a suitable washer or plating where required to maintain low contact resistance.
Usage recommendations
Use appropriate crimping or pressing tools certified for 25 mm² terminals and verify mechanical and electrical continuity after installation.
