Application CaseApplication Case--HubHub
• APPLICATION: Molykote 1000 on Bolts. Bolting the Blades to the Hub
• COMMENTS : Use of Molykote 1000 ensures correct tensioning of bolts therefore better balancing. Good Corrosion Protection is essential as the Wind Mills are mostly installed near to the coasts. The Weight of each blade is 750 kg.
