Cable Looms: The Ultimate Guide to Efficient Cable Management

Have you ever visited a recording studio? Did you ever get time to peek into the automobile’s interiors? What do you see in common? As you can see, there is a massive network of wires, cables, and fibers that connect with each other. And this network transmits signals and electric power to the source. Just imagine if all these wires and cables tangle and get messy. Well, it will be a real nightmare. 

However, all thanks to cable looms, your wires are not messy. Because a wiring loom neatly holds many cables and wires together within its design to help organize wires, they are away from the negative effects of vibrations, abrasions, and moistness. Also, if you use cable looms, there is a proper use of space and a lesser risk of electric fires. Additionally, you will require less time for installation.

Cable Looms vs. Wiring Harness vs. Cable Assembly: Key Differences Explained

While reading about cable looms, you get to read different words. These are either cable assembly, electric wiring harnesses, or wiring looms, which are generally interchangeable. However, they serve the cable management, highlighting different impacts.

• An electrical wiring harness is mainly a sheath made up of thermoplastic material or thermoset. It holds wires and cables in place to make it organized.
• A cable assembly also holds the wires and cables in place. However, it’s the thermoplastic rubber, vinyl, or shrink-wrapped thermoplastics that form its protective covering. This ensures protection from scratch, heat, moisture, friction, and other environmental factors, including harmful chemicals .
• Cable looms means tying or binding wires with certain tools. 

Why Are Electrical Wiring Harnesses Called “Looms”? 

What do you understand by the word “loom”? It is mainly a process that weaves the thread at right angles to make a cloth. Wiring harness assemblies also refer to the same thing. You can use spiral wraps, cable lacing, and electrical tapes for binding. With this, wires coordinate, manage, and function in a better way.

Best Methods to Create Wire Looms

To tame the cable clutter, you can choose from different looming methods. Every method aims to deliver you the best outcome.

Cable ties: 

• Process: Cable ties are small and flat lengths of plastic. There are grooves on one of the flat surfaces. One end of the plastic has a small ratchet assembly with a small open housing. The other end is free. To tie your wires, you need to put the free end through the hole in the ratchet assembly. This will make a loop with wires in between. Once the free end enters the hole, you can pull it tightly to secure it. Once pulled you can only tighten it further.  You can pick plastic or metal cable ties depending on your requirements.
• Use: Industries such as aerospace, food & beverage, medical, etc. use this method.
• Pros: This is a less expensive method of gathering wires together. It comes in different color options for easier identification. 
• Cons: these are generally single-use items.

Braided Sleeving or tubing: 

• Process: Braided cable sleeve is a long tube of mesh material. You can easily cut it with a hot knife. There are several types of braided sleeves available. These are Expandable sleeves (made of polyester or Polyphenylene), Self-closing braided sleeves, & Thermal protection sleeves.
• Use: You can use it in machine tools, robotics, and automatic equipment.
• Pros: With so many varieties, sleeves are useful for different applications.
• Cons: The cleaning part is difficult and is a little bit expensive.

Spiral wrap or tape:

• Process: A spiral wrap is made up of different plastic materials. You can pick from Vinyl Chloride, Polyethylene, Polypropylene, polyolefin, nylon, and PTFE wraps.  This expandable spiral wire wrap has a hole that coils down the length. You can insert your wires and cables into it. As a result, the material inside the spiral becomes securely encapsulated.
• Use: You can use this in aircraft and automotive applications and computer display systems.
• Pros: It is a low-cost method of keeping wires and cables together and to protect them from harm. You can easily remove it.
• Cons: This method is somewhat less pleasing in look than other options.

Wire Twisting: 

• Process: In this method, you twist the wires to bind them together naturally. You can further combine these twisted bundles with cable ties or spiral wraps. 
• Use: Almost every industry uses twisted wires.
• Pros: It is the simplest form of loom forming. It helps in improving functionality by minimizing crosstalk or EMI.
• Cons: It may not hold the bundles for long.

Lacing: 

• Process: Here, a wax-coated fabric strip ties several knots. This binds the cables tightly. 
• Use: You can use this method for military, aircraft, automotive industry, and safety markets. 
• Pros: You get a neat and clean loom resulting in a seamless installation process.
• Cons: Most expensive method as it requires perfection and time.

Which cable looms are best for you?

With many different types of scenarios, The construction of wiring harnesses depends on your requirements and application. It requires deep engineering tactics to make a wire harness. You typically must consider factors such as weight, vibration, abrasion resistance, exposure to moisture, EMI protection, repairability, and temperatures. 

Although technicians use some automatic processes such as laser marking, wire cutting, and automatic testing, it may surprise you that they complete the looming process with their hands.

The process varies from basic to very complex. It generally involves the following steps:

1. First is the design process wherein you finalize the design of the wire harness.
2. The next step is cutting and stripping wires at appropriate lengths.
3. Then, put the wire out on a 1:1 form board.
4. Now, put wires together to form bundles, be it twisted or parallel.
5. Cable ties or lacing cords secure these bundles.
6. Termination of ends that involves contacts, connectors, and backshells.
7. Binding the wires and cables with an outer covering such as sleeves.
8. Electrical testing.
9. Marking and identification.

FAQ

What is wire loom tubing?

Wire loom tubing is a flexible, protective covering designed to organize, insulate, and shield electrical wires and cables. It is typically made from durable materials like polyethylene, nylon, or PVC, offering protection against abrasion, moisture, and environmental damage. Wire loom tubing is commonly used in automotive, industrial, and home applications to ensure neat and safe cable management.

How do extreme temperatures impact wires?

Extreme temperatures can have a significant impact on wires. High temperatures can cause the wire insulation to melt, degrade, or become brittle, leading to short circuits, electrical failures, or even fire hazards. Conversely, extremely low temperatures can make wire insulation rigid and prone to cracking, which can expose the inner conductive material to damage. Special temperature-resistant insulation is often used in environments where extreme temperatures are expected.

Do extreme temperatures deteriorate the integrity of wire looms?

Yes, extreme temperatures can deteriorate the integrity of wire looms, especially if they are made from materials that are not designed for such conditions. Prolonged exposure to high temperatures can cause wire loom tubing to soften, melt, or become brittle, while exposure to extremely low temperatures can make it crack or break. To prevent this, specialized wire loom tubing made from temperature-resistant materials (such as high-temperature nylon or heat-resistant polyethylene) is recommended for harsh environments.
