Fastening and clamping engineering reference organised by turbine location — blade root T-bolt and stud-insert systems, tower L/T-flange connections, cable routing and cleating inside the tower, and yaw/pitch bearing bolt requirements.
Blade root bolting guide: T-bolts vs stud inserts, bolt-circle dimensions, fatigue requirements, installation torque, and inspection intervals for wind turbine blades.
How wind turbine tower flange connections work — L-flange vs T-flange designs, how the ring of bolts is loaded in fatigue, and the preload and bolting practice that keep them tight.
How power and control cables are routed, supported and cleated inside a wind turbine tower — cleat spacing, IEC 61914, and fixing methods at each level.
What yaw and pitch bearing bolts do in a wind turbine, why these rotating-bearing connections are so demanding, and the grade, tensioning and maintenance requirements they carry.
