. Electric railway journal . Dessau-Bitterfeld Railway—Examples of High-Tension Line Construction, Including a Crossing Over Steam Railroad Tracks overhead and two underground 60,000-volt lines. The over-head line was built to forestall delays through the possiblefailure of the underground cable lines and also to deter-mine its influence on nearby parallel low-voltage circuits. cross-arm insulators have guard rings for protectionagainst atmospheric discharges and disruptive arcs. Allinsulators were tested for punctures up to 100,000 voltsand for over-arcing up to volts. The latter test
