What type of stranded rope has all one size wires on the outside layer and another size wires in the next layer?

The stranded rope that features one size of wire on the outside layer while having a different size of wire in the inner layer is known as a Seale rope. This construction technique enhances both durability and flexibility. The outer layer's uniformity in size provides additional protection and contributes to a smoother surface, while the inner layer's varying sizes can improve the rope's overall tensile strength and resistance to wear. This design makes Seale ropes particularly advantageous in applications where strength and flexibility are needed, such as in overhead line construction and maintenance, where they are subjected to various loads and movements. Understanding the specifics of Seale ropes can help linemen choose the right materials for their tasks, ensuring reliability and safety in their work.
