the cables were simply placed in a trench using native soil backfill with minimal soil compaction. Ampacity calculations were performed using typical soil values, but thermal properties were not measured. Since wind turbines operate almost continuously, the feeder cable often ran at maximum capacity....
Underground Duct BankBelow Grade MAXIAMP®Cable Bus required cable spacing between cables and multiple circuits demand a significant amount of real estate. There is an increased risk of natural and/or man-made obstacles due to the size of the trench. Typical trenching requirements are 16 feet ...

A cable duct bank with casing pipes is one of the construction methods that can protect underground power cables from damage due to penetration and traffic above the duct [13]. The outer space of the pipe in the trench is filled with a material that can improve the thermal properties of ...
