Stranded and Solid Cable

When choosing an electrical cable for your work, different important factors need to be checked such as the type of application, how much load it can take, etc. After these primary considerations, the wiring expert should know the difference between a stranded and solid cable, and their contribution to the project.

A solid cable have the ability of a single thick conductor made of solid metal, which lean to be more rigid. The conductor is usually composed of copper. A stranded cable is made up of various small conductor strands (typically 7) that are twisted or grouped together to form a large wire.

Given below are three statements for stranded vs. solid cable.

  • Cable flexibility is an essential component when considering cables for an assembly project. A solid cable with a single metal wire is not flexible or bendable, son it is excellent for applications that don’t require bending. Stranded cables contain of a large number of small singular strand conductors combined together. Hence, stranded cables can hold up over-bending and over-flexing.
  • Solid cables are utilized in structured wirings and in semi-permanent and permanent installations. Other applications of solid cables exclude long distance cable horizontal and backbone cable runs, wall jacks, HD applications, and power over Ethernet (PoE) applications. Usually, stranded cables are apply in patch panels for workstations. Since they are bendable, they can be utilized for applications, where over-flexing is usual.
  • Stranded cables are highly suggested for small distances because they own higher attenuation than solid cables. Attenuation is the property that has reduce in signal strength – analog and digital. On certain occasions, attenuation is the effect of long distance transmission.

Stranded cables are generally recommended for applications 20 feet underground.

Whether you choose a stranded cable or a solid cable, appropriate installation is key to its good performance.
