Choosing the right jacketing material is key to creating a tougher custom cable assembly.
Jacketing material is one of the many features of a custom cable that you should talk about with your cable assembly manufacturer. As the first line of defense against a variety of conditions — including heat, moisture, and chemicals — your choice of jacketing material can make the difference between a durable custom cable and one that fails long before it should. Ensure your finished cable is exactly what you need by covering three main points with your cable assembly manufacturer.
Physical Requirements to Discuss with a Cable Assembly Manufacturer
What is your cable connecting? Do the parts need to move around or are they generally stationary? Does the cable need to stretch? Does it need to resist tears and abrasions? These are just a few of the questions that may come up when discussing a cable’s physical requirements with your cable assembly manufacturer. Once they have the answers, they can weigh the positive and negative characteristics of different jacketing materials to select one that is most appropriate for your cable’s specifications. For example, a polyurethane jacketing has good elastic memory which makes it a solid choice for coil cords and cables that require more flexibility. However, it’s not a good choice if the cable needs to be processed easily.
Beyond the basic physical requirements, a cable also needs to be able to function under a certain set of environmental conditions. These environmental requirements can include resistance to heat, flame, chemicals, and water or even stability over a range of temperatures. There are enough jacketing options available that really fine tuning your cable to the specific conditions of your installation environment is possible in most cases. We can even add a jacketing made of polyvinyl chloride (PVC) that can be made resistant to UV rays or almost as flexibile as a thermoplastic polyestomer.
While the look of a cable may not change its electrical or mechanical performance, the appearance is often more than simple cosmetics. Even something as simple as jacketing in a specific color can enhance the safety of the finished product because it helps better differentiate the finished product from other cables. A jacketing can also be designed to match the equipment manufacturer’s overall design aesthetic, which can help users keep the right cable with the right equipment.
Finishes can be matte or glossy, depending on your needs. In some cases, a matte finish can make the cable easier to grip, which can be useful for installation and handling in certain conditions. For medical equipment, there are also requirements for cables that may come into contact with skin that include cleaning, disinfection, and sterilization that may dictate the properties of the jacketing.
Jacketing material is one of the many features a cable assembly manufacturer is able to customize to meet your specific needs. With all the options available, it’s important to have an in-depth discussion with an experienced design team to make sure they have all the information they need to select the right materials for your cable.
