Why Choose the Cembre 2502410 Heavy Duty Twin Hole Copper Tube Crimp Lug?
The Cembre 2502410 is a premium heavy-duty twin-hole 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 exceptional mechanical strength and dependable long-term electrical performance.
Manufactured from annealed high-purity electrolytic copper with an electrolytic tin-plated finish, the terminal provides outstanding electrical conductivity while offering excellent resistance to corrosion and oxidation. Its long closed barrel improves both electrical and mechanical performance, while the absence of an inspection hole helps prevent moisture ingress, making it ideal for outdoor and medium-voltage applications up to 35 kV.
The Cembre 2502410 is the 2A10-2M12 version, designed for 50 mm² copper conductors with twin M12 fixing holes on a 44.5 mm hole centre spacing. The twin-hole palm provides improved mechanical stability and resistance to vibration, making it ideal for substations, switchgear and heavy-duty power connections.
