Cable vs. Wire: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on December 31, 2023
A cable is a thick, strong rope made of wires twisted together, used for electrical transmission or to bear mechanical loads, while a wire is a single conductor, usually made of metal, used to carry electricity or a signal.
Key Differences
Cables are typically composed of multiple wires bundled or twisted together, often insulated, designed for strength and transmission of larger currents. Wires, on the other hand, are single, slender strands or rods of metal, often used where flexibility and ease of installation are important.
Cables are commonly used in electrical power transmission, telecommunications, and for bearing mechanical loads, requiring robustness and durability. Wires are more frequently used in smaller-scale electrical and electronic applications, such as in circuitry, where precision and flexibility are key.
Cables, due to their multiple-wire composition, often provide greater strength and durability but may be less flexible than single wires. Wires offer high flexibility and are ideal for applications requiring intricate bending and shaping.
In telecommunications, cables, such as coaxial or fiber-optic, are designed for efficient and high-capacity signal transmission. Wires, while also used for signal transmission, are more common in simpler, low-capacity applications.
Cables usually have multiple layers of insulation and protective sheathing, safeguarding against environmental factors and interference. Wires may have minimal insulation, relying on their simplicity and ease of integration into various devices.

FAQs
What is a wire?
A wire is a single, usually metal, conductor used for carrying electricity or a signal.
Can cables be used for data transmission?
Yes, certain types of cables, like fiber-optic cables, are specifically designed for data transmission.
Is a cable stronger than a wire?
Generally, cables are stronger due to their composite structure of multiple wires.
What's the difference in flexibility between cable and wire?
Wires are usually more flexible than cables.
What is a cable?
A cable is a thick, strong rope made of wires twisted together, used for various purposes like electrical transmission or mechanical support.
Is cable or wire better for outdoor use?
Cables, due to their robust construction, are generally better suited for outdoor use.
Are cables used in computers?
Yes, various types of cables, like USB or Ethernet cables, are used in computer networking and connections.
Are wires always made of metal?
While most wires are metallic, some are made of other conductive materials like carbon or aluminum.
Can wires be insulated?
Yes, wires are often insulated to prevent electrical hazards and interference.
Are all cables flexible?
Not all; some are designed for rigidity and strength, like those used in bridges.
Are cables more expensive than wires?
This depends on the type and purpose, but cables are often more costly due to their complex structure.
Can wires be used underwater?
Specialized wires with waterproof insulation can be used underwater, but cables are more commonly used for underwater applications.
What type of cable is used for internet?
Coaxial or fiber-optic cables are commonly used for internet connections.
Can a wire be used for heavy lifting?
Generally, no; cables are preferred for heavy lifting due to their strength.
Is it safe to handle wires and cables?
Safety depends on their use and whether they are carrying current; handling live electrical wires or cables is hazardous.
