The most important thing for a longer cable installation is to choose a suitable path. Not necessarily the shortest path here is the best, but also pay attention to the right to use the land, the possibility of erection or buried. Must have a very complete design and construction drawings, so that construction and future inspections are convenient and reliable. During construction, be careful not to subject the outdoor cable to heavy pressure or to be damaged by hard objects. When the cable is turned, its turning radius is greater than 20 times the diameter of the cable itself.
