What type of cable pattern creates a small diameter, high current carrying capacity conductor?

The segmental cable pattern is designed specifically to optimize the conductor's cross-sectional area while maintaining a compact diameter. This design allows the conductor to have a high current carrying capacity compared to other cable patterns. By using a segmental construction, the cable can minimize the amount of insulation and other materials needed, which in turn keeps the overall diameter low without compromising the electrical performance and heat dissipation.

In contrast, the sector shape is often used for different applications focused more on structural stability rather than compactness, coaxial cables are built for shielding and transmission properties, and twisted pairs are frequently used in telecommunications to reduce interference rather than optimize for current capacity. Thus, the segmental pattern is the most effective choice for achieving both a small diameter and high current capacity.
