Power Cable Splicing and Terminating Guide
76 volts per mil, while most cable insulation have dielectric strengths over 700 volts per mil. Without strand shielding, an electrical potential exists that will over-stress these air voids. As air breaks down or ionizes, it goes into corona (partial discharges). This forms ozone, which chemically deteriorates cable insulation. The semi-Get Price >>
