What’S The Difference Between A Cable Assembly And A Wire Harness?

Posted by Bob LeGere on Mon , March 19, 2018
When sourcing electrical components for product development, you’ll often see the terms “cable assembly” and “wire harness” used interchangeably. People also mistakenly use the terms “cable” and “wire” synonymously. But in truth, these components couldn’t be more different. Sure, they’re both used in electrical and communication fields to route electricity between different locations. But that’s where the similarities end. Each has a distinct purpose, which means the success of your product depends on selecting the right one based on the specifications of the application. Here’s a brief overview of the differences between cable assemblies and wire harnesses to help you make the right choice.
Wire Harness
Wire: Un solo conductor (normalmente de cobre o de aluminio). Los cables están baja resistencia, bajo coste, y medido por “calibre”. Cuanto menor sea el calibre, más grueso es el alambre. Cuanto más grueso es el cable, mayor es el riesgo de daños resultantes de un fusible quemado.
Open up a wire harness, and you’ll find multiple wires, each donning its own single layer of exterior covering. This covering is typically made from a thermoset or thermoplastic material, and serves two primary purposes:

1.To protect outside stimuli (like environmental materials or even technicians) from harm caused by the flow of electricity.
2.To ensure electrical systems are organized and easy for technicians to navigate.
The jacketing material that covers each wire does little to protect the wire itself, which is why this solution is typically employed in applications where moisture, dust, temperature and friction are not a concern—for example, when the wires will exist inside a housing unit or shell, like a remote control.
Montaje de cable
del cable: Dos o más conductores envueltos en una sola chaqueta. La mayoría de los cables consisten en un alambre positivo que transporta la corriente eléctrica, un cable neutro que completa el bucle eléctrico y un cable de tierra.
Like wire harnesses, cable assemblies are groups of wire or cable that also have an exterior covering. But the entire bundle is encased in an extremely durable sheath made of material, like shrink-wrapped thermoplastic, rubber, or vinyl. Cable assemblies serve three main purposes:
1.To protect outside stimuli (like environmental materials or even technicians) from harm caused by the flow of electricity.
2.To ensure electrical systems are organized and easy for technicians to navigate.
3.To protect the wiring or cable against wear and tear or other harsh environmental conditions.
Cable assemblies are custom-designed to address logistical challenges such as size constraints, extreme temperature exposure, fire, moisture, dust, friction, chemical substances exposure, flexibility and more. Because of the level of customization available with a cable assembly, they can also be ordered in a variety of shapes, sizes, and colors.
If this overview still doesn’t provide you with a clear answer, don’t hesitate to reach out to a custom connector manufacturer. They are experts at outfitting products with the right electrical components given all specifications and can custom design an electrical system that meets all your project needs, including cost and turn-around time.
