Protection of Communication Cables in Plastic Sheaths from Lightning Strikes,

Abstract

From impulse generator tests on a cable 4 km in length (a one-quarter cable with polythene-insulated cores, an aluminum foil screen in the form of a two-layer winding of steel wires each 0.25 mm in diameter; enclosed in P.V.C. cover; outside diameter of cable of the order 15 mm), it was found that protection by earthing the cable screen along the line is generally less effective than protection by laying a lighting conductor of bimetal 0.25-0.35 m deep, although cost considerations and local conditions may influence the choice in particular cases.
