Maximum transmitted power of ESP shafts

[ALEngineer]

ESP shaft ratings: maximum transmitted (allowable) power in kW by shaft diameter, strength class T8-T14, and spline type. Use this when selecting pump / protector / motor shafts in the downhole string.

Maximum transmitted shaft power

Column banners on the scan, top to bottom:
- Shaft diameter, mm
- Strength class
- Permissible shaft power, kW
- with straight-sided splines: at 50 Hz, normal start; at 60 Hz, soft start
- with involute splines: at 50 Hz, normal start; at 60 Hz, soft start

14 mm has no straight-sided spline ratings. For 28 mm, involute splines are split by module m=1 and m=2.
