Aerial cable should pay attention to what the problem?

Overhead cable laying method other than a requirement is the most special elongationshould be less than 0.2%, the project structure and framework should be based on fiber optic cable hanging overhead cable sag is calculated, and shall account for fiber elongation,so take the set cable sag cable elongation can guarantee no more than the specified value.In addition to elongation, the aerial cable way than laying fiber optic cable to pay attention tomine, as already described, not repeat them. Overhead cables are generally three kinds ofways, including: hanging wire prop hanging, hanging wire winding and self-supporting.Should be based on the specific situation, and so the best option.
