Why Choose the Cembre CA70S-M12 Copper Compression Cable Lug?
The Cembre CA70S-M12 (2531430) is a premium medium-voltage copper compression cable lug designed to provide secure, low-resistance electrical terminations for industrial power distribution, substations, switchgear and utility applications. As part of the proven Cembre CA-M series, it delivers outstanding electrical conductivity, excellent mechanical strength and dependable long-term performance in demanding environments.
Manufactured from high-purity annealed electrolytic copper (>99.9%) with an electrolytic tin-plated finish, the CA70S-M12 offers exceptional corrosion resistance while maintaining superior conductivity. Its extended barrel improves both electrical and mechanical performance, while the closed barrel design without an inspection hole helps prevent moisture ingress, making it suitable for outdoor installations and medium-voltage applications up to 35 kV.
Designed for 63–70 mm² sector or 70 mm² round copper conductors with a single M12 fixing hole, the CA70S-M12 is ideal for industrial control panels, switchgear, substations, renewable energy installations and critical electrical infrastructure requiring reliable cable terminations.
