Basic Technical Requirements for ADSS Cable Erection Construction


1. Requirements for tension and lateral pressure in ADSS fiber optic cable construction


The glass core in the ADSS fiber optic cable is very fragile and will be damaged by stretching and lateral pressure. Therefore, the optical cable cannot be squeezed and stretched beyond the standard when the optical cable is installed in the facility.


During construction, a tension pay-off machine should be used for tension pay-off, the traction tension must be stable, the traction tension cannot exceed the index requirements, and the tension and side pressure in the installation of ADSS fiber optic cable cannot be too large.


2. Requirements for the outer sheath of ADSS fiber optic cable


The flat and smooth surface of the outer sheath of the ADSS fiber optic cable can effectively reduce electrical corrosion. If the outer sheath of the optical cable is worn, scratched, or broken, the optical cable will be corroded and damaged in a short time. Therefore, when the fiber optic cable is in the erection, it must not rub or collide with the ground, branches, houses, spanning racks, poles, towers, and the edge of the cable reel, and metal tools must not be used to scratch the fiber optic cable.


3. Requirements for bending radius of ADSS fiber optic cable


The bending of the ADSS fiber optic cable is limited. Exceeding the limit will cause damage. The bending radius of the optical cable is as follows:


The bending radius of the optical cable during construction is ≥30D (D is the diameter of the optical cable);


The bending radius of the optical cable during operation is ≥20D (D is the diameter of the optical cable).


4. Other aspects of ADSS fiber optic cable


ADSS fiber optic cable will be damaged if it is twisted in the longitudinal direction, so non-polar insulated braided traction rope and anti-torsion device must be used during construction.


The glass core in the ADSS fiber optic cable will break when it is damp with water. Therefore, the end of the optical cable must be sealed with waterproof tape during construction when it is in the opening test or after the completion of the construction.
