The ADSS cable is suspended in the electrical field due to the phase conductors; this varies from a maximum at mid-span to zero at the grounded metal supports of the cable. In dry conditions, no current flows on the jacket of the cable, but moisture reduces the jacket insulation. Uneven distribution of moisture can result in formation of high-resistance "dry bands" which have a relatively high voltage across them. Dry bands tend to form at the supports. Voltage across the dry band can cause carbon tracks to form and erosion of the jacket material. If the voltage across the dry band is high enough, an arc may form which can damage the jacket. Dry-band arcing is more likely for cables installed under higher transmission voltage lines (220 kv and above). Even a few incidents of arcing along a dry band can cause severe permanent damage to the jacket, leading to subsequent failure of the cable. Relatively low sustained arc currents of a few milliamperes can cause eventual aging degradation of the cable. The magnitude of current available in an arc (and probability of damage) depends on the geometry of the installation and is not simply correlated with the voltage of the transmission line. Wetting conditions near industrial plants or saltwater will have more severe effect on the jacket resistance than in freshwater rain or fog. While one measure to protect cables from dry-banding damage incorporates a semiconducting layer to equalize potential, a more feasible method uses externally applied protection within 50 metres of each support, since this is the area most susceptible to damage.
