Blades
The reinforced carbon fiber/glass blades are covered by a protective tape made
of abrasive polyurethane on the leading edges of the blades.
After years of use, this tape may be affected by weather conditions. If the tape is
missing or partially missing, contact your local installation office to have the
tape replaced. By failing to replace the tape, the life of the blade will be seriously
reduced due to the strong erosion the blade is exposed to.
Shock absorber
The wind turbine has one hydraulic shock absorber installed that prevents abrupt
shocks by promoting fast braking and slow return to its original position.
The shock absorber has a little slack at the beginning of its return movement,
and this is normal. However, if this slack is observed to continue for over half the
return movement, and if oil is leaking, the shock absorber must be replaced.
Lubrication
Bornay wind turbines have three moving parts:
The front shaft (blades-alternator) is equipped with sealed bearings and covered
with lubricant. It does not need any special attention; its lubricant will last
during its lifetime.
The yawing shaft (windmill-tower) is equipped with sealed bearings and covered
with lubricant. It does not need any special attention; Its lubricant will last
during its lifetime.
The alternator shaft (alternator-yawing system) is a stainless steel tube covered
with lubricant. It does not need any special attention. Its lubricant will last
during its lifetime.
