Why Choose the Cembre 2503008 Heavy Duty Copper Tube Crimp Lug?
The Cembre 2503008 is a premium heavy-duty copper tube crimp lug designed to provide secure, low-resistance electrical terminations for stranded copper conductors in demanding industrial, utility and power distribution applications. Manufactured by Cembre, this compression terminal delivers outstanding mechanical strength together with dependable long-term electrical performance.
Manufactured from annealed high-purity electrolytic copper with an electrolytic tin-plated finish, the terminal provides excellent electrical conductivity while offering exceptional resistance to corrosion and oxidation. Its double-length closed barrel enhances both electrical and mechanical performance, while the absence of an inspection hole prevents moisture ingress, making it particularly suitable for outdoor and medium-voltage applications up to 35 kV.
The Cembre 2503008 is the 2A14-M8 version, designed for 70 mm² copper conductors with an M8 stud connection. It is widely specified for industrial switchgear, substations, OEM machinery, electrical control panels and power distribution systems.
