The new slip ring harness design addresses one of the most common failure modes in many wind towers. The increase in production hours and decrease in maintenance time, when spread across an entire wind farm, produces an impressive ROI.

TPC Wire & Cable Corp. is introducing a new slip ring harness for wind turbines that has proven to increase cable life thereby decreasing downtime caused by constant replacement. Although environmentally friendly compared to other power generation, anyone involved in the operation and maintenance of a wind farm knows the extreme conditions and challenges that arise from the severe operating environment inside the tower. TPC’s solution addresses cable flexibility, ease of installation and ability to outlast ordinary cable.
TPC consulted with several major wind farm owners to design and develop a slip ring harness that addresses the multiple failure modes encountered in the tower. The TPC harness was designed to be flexible at all temperatures, easy to install, and last many years in the abusive wind tower environment.
The slip ring harness controls the three blade pitch motors. This harness is subject to constant abuse in the form of torsion, oil exposure, abrasion and temperature extremes. When ordinary products fail in this harsh environment, the wind farm experiences significant downtime, loss of revenue, and maintenance expense.
Snaking the harness through 90 degree elbows, and terminating individual conductors to terminal blocks in very tight clearance areas had previously been very difficult, especially in cold weather. The highly flexible TPC harness is much easier to install at both the hub end and the slip ring end.
“The new slip ring harness design addresses one of the most common failure modes in many wind towers. The increase in production hours and decrease in maintenance time, when spread across an entire wind farm, produces an impressive ROI,” explains Paulette York, Wind Energy Segment Manager.
TPC’s long-lasting, dependable wire and cable products solve the most difficult application problems in the harshest environments resulting in lower overall costs and increased production time. TPC outperforms and outlasts ordinary cable 10:1.
