Experimental investigation of aging effects of dry-band arcing on ADSS fiber-optic cables

A testing method for evaluating the quality of ADSS fiber optic cable is presented. Aging effect due to arcing under different voltage and pollution levels (heavy and light) is described. Measurement of area and depth of damaged cable is conducted to analyze the damage severity. Experiments show that 2 mA and 7 kV are threshold current and voltage which might cause cable failure. Cycle to failure of the cable decreases from 330 to 65 when voltage changes from 11 kV to 14 kV, and it is inversely proportional to the damage area of the cable.
