Fiber Cable Manufacturer
ADSs fiber optic cable mounted on the high-voltage transmission line, its general life span of more than 25 years, and the factors affecting its life are many,
The main factors are:
(1) The High voltage induction electric field gradient near the pole tower changes greatly, and the high voltage induction electric field has strong electrical corrosion to the fiber optic cable.
General KV and the following overhead power lines with PE type, 110KV and above the line with at type;
(2) for the two-loop tower, due to the line of the first circuit power outage or line modification, in the choice of hanging point to be considered;
(3) When the line passes through the working zone with salt mist acid gas, the chemical material will corrode the optical cable skin, its electric protection sleeve is damaged, easy to be harmed by the arc;
(4) Improper construction caused by skin injury or wear, etc., in the long-term high-voltage electric field operation, its surface is easy to corrode, the outer sheath smooth and smooth fiber optic cable can effectively reduce electrical corrosion and prolong life.
