Custom Cable Assemblies and Cable Lanyards
There are many things to consider when it comes to engineering the most effective cable assembly or cable lanyard for your application. First of all, what type of load will the cable assembly be subject to? Is it tension, compression, static, or dynamic?
Next, one must figure out the work load, shock load (if any), safety factor, and durability considering the environment. For the cable selection, it is important to consider the construction, the diameter, and whether it should be bare or coated. The type of fittings and terminals need to be initially selected and then we will determine whether standard or custom fittings are required.
Finally, one needs to decide whether the tolerance conditions should be tight, normal or relaxed. By considering these mentioned factors, the results of your custom cable assembly or cable lanyard will be as efficient and effective as possible.
Safety Factor Ratios
|Ratios to Determine Min. Safety Factors||Min. Breaking Strength of Cable : Maximum Working|
|Normal Conditions||5 :1|
|Shock or Peak Load Conditions||8:1|
|Critical or Safety Conditions||10:1|
