Types of Copper Conductors

Description: Solid, single-strand copper conductors with high conductivity and rigidity.
Applications: Ideal for fixed installations where minimal movement is expected, such as household wiring and industrial conduits.
Advantages: Higher mechanical strength, easier to terminate, and cost-effective for fixed installations.

Description: Multi-strand copper conductors offering superior flexibility and ease of handling.
Applications: Suitable for applications requiring frequent movement or bending, such as portable equipment, machinery, and control panels.
Advantages: Enhanced flexibility, better resistance to fatigue, and easier installation in tight spaces.
