Note:
• The data in the table are based on including the hydraulic kit.
• The maximum distance is calculated using the cable diameters shown in this table. For
longer lengths, and for cables laying with other cables, re-calculate the minimum cable
diameter to a higher value to allow for any electromagnetic or harmonic effects.
