Wind Turbine Slip Ring
LPW Series Aiming at special requirements of wind power generator system and real applied environment in China, this kind of slip ring was researched and developed for special purpose in Chinese wind power generator system.
Adopting advanced imported material, inner part of this slip ring is equipped with advanced producing instrument and numerous testing system that are aiming at all capacities of wind turbine slip ring.
This series product is characterized by excellent low temperature resistance, sandstorm resistance, corrosion resistance, impact resistance, shock resistance, reliable capacity and no requirements of frequent maintenance. Working life time is over 20 years or hundred millions of revolutions. At present, this series of product has been applied successfully in many wind power stations in China.
Description
The wind turbine slip ring is higher in rotary accuracy, stronger in anti-shock capacity, more reliable in performance, and longer in life time when comparing with similar products. Adopting advanced imported graphite contact material ensure good conductivity and lubricity, and it is low in torque, stable in operation, low in resistance fluctuation and contact resistance. Abrasive blasting oxidation technology of outer shell processing makes it adapt to salt and fog, sandy and dusty, frozen, thunderstreak and earthquake environment. Extra advantages are equipped with accelerate the monitoring (for protection), adjustable rotation remaining holder, and detachable brush block. Professional design, normalized and standardized production create remarkable quality.
