Connecting electrical components in industrial and commercial settings requires special wiring solutions. Cable assemblies and wire harnesses are two of the most popular electrical wiring options available, but what’s the difference between them?
In this blog post, we’ll discuss the distinctions between cable assemblies and wire harnesses, including their design features and applications, so that you can determine which is most suitable for your project. This information is invaluable to engineers and technicians who work with these electrical components daily.
Cable Assemblies vs. Wire Harnesses
Cable assemblies are groups of cables arranged into a single unit. These point-to-point, single-connector components sometimes include loopbacks or multiple legs but don’t involve any advanced layout. On the other hand, wire harnesses are a specially designed system for organizing wires or cables. It simplifies the assembly of large, multi-faceted wiring systems.
Their similarities include the following:
- Protect and organize wires
- Transmit signals from one point to another
- Conduct electric power
- Secure wires in place
Physically, their defining feature is the complex arrangement of many wires and cables. Numerous industries utilize these systems for diverse electrical applications, especially those where separate cables are paramount to prevent safety hazards in the workplace.
Differences Between Cable Assemblies and Wire Harnesses
Wires are a single strand of electrical conductors, while cables are two or more insulated wires bundled in a jacket. Wire harnesses and cable assembly are often used interchangeably. However, it’s evident that their respective applications are different.
Their key differences include the following:
Cable assemblies are predominantly utilized in outdoor settings, especially in extreme environments. It has an exceptional resistance against dust, moisture, and heat, making it an ideal option for more stressful applications. Additionally, it can effectively protect wires and cables against corrosion and friction.
Meanwhile, wire harnesses offer minimal protection since they’re mainly utilized to organize wires. Therefore, it can’t safeguard or shield electrical wires against harsh elements.
Wire harnesses are the best choice for low-cost electrical solutions that guarantee wires and cables stay organized. Its primary job is to ensure the wires and cables remain intact within a system. Although they’re more affordable, the wire harness configuration still depends on the type, number, and quality of wires used in a project.
Cable assemblies usually require more resilient materials that can withstand harsh environments, making them slightly more expensive. However, their durability and resistance to rigorous conditions make them a cost-productive solution in the long run.
Another difference between a wire harness and a cable assembly is their physical appearance. Wire harnesses encase single wires so that these wires can be easily seen and removed individually from the harness. A cable assembly bundles multiple wires with a single external sleeve or jacket, so it comes as one thick wire.
Cable assemblies and wire harnesses are often found alongside each other. However, their specific uses are dissimilar. For instance, wire harnesses are employed in household products for easier access during maintenance or repairs. Meanwhile, cable assemblies are commonly used in severe environmental conditions or extreme temperature changes.
Applications for wire harnesses:
- Household appliances
- Consumer electronics
- Electrical systems
Applications for cable assemblies:
- Automobile wiring
- Heavy industrial machineries
