Cembre C350-58 colour-coded copper compression lug for 350 kcmil (185 mm²) conductors with M16 fixing hole, red colour coding, inspection hole and electrolytic tin-plated finish.
£16.65
The Cembre 2397580, manufacturer reference C350-58, is a heavy-duty colour-coded copper compression ring terminal engineered for terminating large copper conductors in industrial power distribution, switchgear, transformers and renewable energy systems. Manufactured from annealed electrolytic copper with a purity greater than 99.9%, it delivers excellent electrical conductivity together with outstanding mechanical reliability.
The terminal features a chamfered barrel entry and integrated inspection hole to simplify conductor insertion and ensure correct cable positioning before crimping. Its electrolytic tin-plated finish provides excellent resistance to oxidation and corrosion, making it suitable for demanding industrial environments and long-term service.
Designed for 350 kcmil (approximately 185 mm²) copper conductors, the C350-58 incorporates a 5/8-inch (M16) fixing hole and red colour coding for rapid identification of the correct conductor size and compatible Cembre compression die.
Compression cable lugs provide permanent electrical and mechanical connections between large copper conductors and equipment such as switchgear, transformers, generators and busbars. When installed using compatible Cembre crimping tools and dies, they produce secure, vibration-resistant terminations with consistently low electrical resistance.
The Cembre C Series combines premium copper construction, precision manufacturing and colour-coded identification to simplify installation while delivering dependable performance across industrial, commercial, renewable energy and utility applications.
