A solid wire comprises a single metalcore while a stranded wire contains a large number of twisted wires that are wrapped together to form a helix-shaped bunch. Today you’ll learn 10 essential differences between both types of wires. Let’s understand stranded vs solid wires.
The small diameter strands can easily face bending. The wire strands facilitate the movement in curves, twists, arches or any other shape. Bend it in any direction and you’ll never get disappointed. A solid wire is less flexible than stranded. It offers little flexibility and it might crack in case of bending.
A single solid piece of wire can be easily manufactured with a little technical knowledge. The sophisticated technology and expertise required for small diameter strands make the stranded wire expensive. Thus solid wires are more economical and are available at cheaper rates as compared to stranded ones.
Under the ordinary condition where bends and vibrations are not expected the single piece of thick wire is resistant to damages and hazardous environmental conditions. Thus a solid wire is more durable than stranded.
Electrical power transmission systems always utilize stranded wires, and one can observe this practice in all overhead lines. The reason is greater flexibility against mechanical vibration and fatigue.
Breadboard and Electronic circuits
The connecting wires on breadboard and electronics circuits counter enormous movement while assembling components. Stranded wires well suit this scenario, however, it is difficult to mount strands on board. A soft drawn single solid wire is preferred in breadboards.
Robotics and Automotive
Wires in robotics and automotive industry are stranded.
Solid wires are resistant against corrosion and are ideal for outdoor applications where stranded wires are least effective against corrosion.
EI and RI
EI and RI effect is more prominent on stranded cables.
For the same diameter, a solid wire carries more amount of current.
The manufacturing process involved with solid cables is simple whereas a stranded cable is complex.
