Why Choose the Cembre 2509070 Compression Cable Lug?
The Cembre 2509070 is a premium heavy-duty tin-plated copper compression cable lug designed to provide secure, low-resistance electrical terminations for demanding industrial, utility and medium-voltage power applications. Manufactured by Cembre, this high-performance connector delivers exceptional electrical conductivity, outstanding mechanical strength and long-term reliability.
Part of the proven Cembre 2A-M Heavy Duty series, the 2509070 (series reference 2A80-M14) is manufactured from high-purity annealed electrolytic copper with an electrolytic tin-plated finish to resist corrosion. Its double-length barrel maximises conductor contact while the closed-end design without an inspection hole prevents moisture ingress, making it suitable for indoor and outdoor installations up to 35 kV.
Designed for 400 mm² copper conductors, the lug features a single M14 fixing hole, making it ideal for switchgear, transformers, substations, industrial control panels, renewable energy systems and heavy-duty power distribution equipment.
Single M14 stud fixing for secure equipment connections.
Double-length barrel for enhanced crimp performance.
Closed-end design prevents moisture ingress.
Excellent electrical conductivity with low contact resistance.
Outstanding resistance to vibration and mechanical stress.
Suitable for industrial and medium-voltage installations up to 35 kV.
