Your wind turbine’s power and data cables may be wearing faster than you think

By Paul Dvorak What a mess. This drip loop has made about one nacelle revolution and the yaw motors will have no trouble twisting it once more. This turbine’s owner should expect major insulation wear and eventually, exposed conductors.
The drip loop is the bundle of cables responsible for carrying all the power, data, signals, and communication for everything generated inside a nacelle. The loop is needed to provide enough slack for the turbine to yaw a few revolutions keeping it pointed into the wind.
While the cables in this loop meet wind industry standards, especially for torsion, oil resistances, and temperature, current industry practice
