Wind turbines have been maintenance nightmares for many operators over the past few years. This is to be expected when the rush to install wind turbines has avoided the usual developmental learning curve, on which new technologies mature by trial and error. Instead, many turbine designs have, until very recently, been taken from other industries…
What are the electrical & electronic components in a wind turbine?
Motors and drives: nacelles on utility scale turbines are filled with motors and drives. The latter devices are part of the turbine controls that tell motors what to do. Generally, electric motors pitch the blades on turbines with less than 1.5 MW outputs and point nacelles in appropriate directions. Utility-scale turbines can have up to…
Corrugated tubes protect wind turbine cables
Corrugated tubes protect cables in wind turbines against impact and abrasion. The tubes are flexibile, extended fatigue life, and can be paired with straight or 90° tube connectors, seals, and O-rings. The durable polyamide corrugated tubes come in 15 different sizes with inner dimensions ranging from 2.8 to 47.7 mm. They can be supplied as…
