7. er cable control cable and the standing pole of the lightning rod e For suburb and rural areas it s recommended to adopt direct burial for the transmission cables Overhead wiring is prohibited because it s more likely to encounter lightning strike Use shielded cables or thread the cables through metal tubes for burial thus to ensure the electric connection to the metal tube In case it s difficult to thread the cable through the tube all the way it s acceptable to use tube threaded cables only at both ends of the transmission line yet the length in burial should be no less than 15 meters The cable sheath and the tube should be connected to the lightning proof grounding device e Additional high power lightning proof equipment and lightning rods should be installed for strong thunderstorm or high induced voltage areas such as high voltage substation The lightning protection and grounding for outdoor devices and wires should be designed in line with the actual protection requirement national standards and industrial standards The system should perform equipotential grounding by streaming shielding clamping and earthing The grounding device must meet anti interference and electric safety requirements There should be no short circuiting or hybrid junction between the device and the strong grid Make sure there s a reliable grounding system with grounding resistance below 40 below 100 for high soil resistivity regions
