Fiber Cable Manufacturer
Since the ADSs cable is dancing with the high-voltage power line, its surface, in addition to requiring the same anti-ultraviolet radiation as ordinary optical cables, also requires long-term experience of high-pressure strong electrical environment test. The coupling between the fiber optic cable and the high-voltage phase line and its capacitance with the earth will produce different spatial potentials on the surface of the fiber optic cable. In the rain and snow frost and other meteorological environment and dirt, the potential difference in the wet and dirty fiber optic cable surface local leakage current, the resulting thermal effect of the fiber optic cable surface parts of the water evaporation, in the moment of evaporation, leakage current interrupt to produce arc and large heat energy, accumulated heat energy will burn the surface of the cable, forming like a branch shape This is what is said to be an electrical mark. Day after day external protective layer aging damage, testers, Aramid yarn aging mechanical properties reduced, eventually there will be optical cable fracture. Mainly from two aspects to solve this problem. First, the use of special anti-electric trace sheath to squeeze the outer protective layer outside the aramid yarn, that is, the use of anti-electric trace sheath to reduce the strong electricity on the surface of the optical cable corrosion; In addition, through professional software to calculate the space potential distribution on the power tower and draw an electric field strength distribution map, according to this scientific basis to determine the specific suspension point of the optical cable on the tower
, so as to avoid the fiber optic cable being affected by a stronger electric field.
