Why Choose the Cembre CA40S-2M12 Copper Compression Cable Lug?
The Cembre CA40S-2M12 (2530510) is a heavy-duty two-hole copper compression cable lug designed for secure electrical terminations in medium-voltage power distribution systems. As part of the Cembre CA-2M series, it provides exceptional mechanical stability, excellent conductivity and long-term reliability for demanding industrial and utility applications.
Manufactured from high-purity annealed electrolytic copper with an electrolytic tin-plated finish, the CA40S-2M12 offers excellent corrosion resistance and outstanding crimp performance. The extended barrel enhances both electrical and mechanical characteristics, while the closed barrel design without an inspection hole helps prevent moisture ingress, making it ideal for outdoor installations and medium-voltage applications up to 35 kV.
Designed for 30–40 mm² copper conductors, the terminal features two M12 fixing holes spaced at 44.5 mm centres, providing improved resistance to vibration and electrodynamic forces in switchgear, substations and industrial power systems.
