Cold storage units regularly operate at sub-zero temperatures, with some dipping as low as -30. This presents a problem when it comes to actually running a cold storage unit. The very nature of a cold storage unit provides designers and manufacturers with a range of design-based headaches. Take cables, for example. Cables are required to power a cold storage unit; they basically keep the unit online and whatever it is the unit happens to be cooling at a low temperature. Unfortunately, extreme temperatures can play havoc with the operation of a cable, with the cable potentially freezing and losing functionality. This leads to the entire unit failing. Not long ago, we at Custom Designed Cables were presented with this exact problem. In order to come up with a solution, we had to embark on an intense course of experimentation and trials to find a combination of materials that would be able to withstand the extreme cold, as well as a way of constructing them so that their operation would not be compromised. We came up with two innovations that dealt with two of the major issues presented by a cold storage the facility. By using silicone cores in a multicore cable and developing hybrid over sheathing materials, we hit upon a combination that was shown to improve the longevity of the cable, even in extreme temperatures. We then set about improving the mechanical strength of the cable by combining various cable braiding combinations, attempting to hit on a combination that would suit the needs of the application while also providing a robust and strong cable. Other considerations, depending on the location of the cable, include cable shielding so that the operation of the cable isn’t compromised by any near-by devices that may cause interference. If a cold storage unit requires a constant feed of data for monitoring purposes, the cable will also need to include data transmission capabilities. On the whole, constructing a cable for cold temperatures is difficult but not impossible. With a bit of experimentation and extensive trailing, like that carried out by Custom Designed Cables before we start any project, the perfect solution will soon emerge!
