Latest Patents

Shimokura's latest patents include advancements in overhead cable design. One patent describes an overhead cable that features an outermost surface formed by twisting together a plurality of segment strands. This design incorporates spiral grooves that create recesses with substantially rectangular cross-sections, strategically placed at intervals around the cable. The outermost layer consists of thin segment strands and at least one thick segment strand, which are twisted together to form a unique mating structure. This configuration minimizes the contact length of the recessed and projecting surfaces, optimizing performance.

Another patent focuses on a low sag, low wind load cable. This cable is designed with segment strands of a sector-shaped cross-section, twisted at the outermost layer, and includes grooves at the adjoining portions of the segment strands. The cable features tension-bearing cores made from materials with specific linear expansion coefficients and elastic moduli. This innovative design significantly reduces wind load and sag, even under high temperatures, ensuring stability during adverse weather conditions.
