Which type of ropelay stranded conductor is more flexible?

Bunched stranded conductors are known for their flexibility primarily because of their construction. In a bunched conductor, multiple strands of smaller wires are twisted and grouped together, which allows for greater movement and bending without causing damage to the conductor. The arrangement of strands tends to have fewer contact points and is not tightly wound, which minimizes the stiffness typically found in other conductor configurations.

This flexibility is advantageous in applications where the wire needs to navigate through tight spaces or where movement is required without risking breakage. The design of bunched conductors allows them to easily adapt to the shape of the installation environment while maintaining electrical performance.

In contrast, twisted and layered constructions can be less flexible due to their tighter arrangements, which may create stiffness, making them less suited for portable or mobile applications. Solid conductors, while efficient in terms of electrical conductivity, lack flexibility altogether as they are made from a single piece of material without any microbial movement capacity.
