This is similar in notion to your gravity movement of h2o on sloped flat locations to roof drains or in gutter to downspout systems. Cables must be routed using prolonged smooth bends of no less than ninety degrees. Lightning will position major mechanical force on cables, and sharp bends or corners is often broken or lightning can arc above during the worst circumstances. This mechanical drive is usually in comparison with sending pressurized water through a hearth hose – the conductor will attempt to straighten by itself making a injury problem for splice fittings, fasteners, or maybe the conductor by itself.
