Submersible drop cables

The submersible drop cables for SQF pumps are
approved for use in drinking water (KTW approved).
The material of the submersible drop cable is EPR.
The table below shows the maximum length of the
submersible drop cable for the different sizes of cable,
allowing for a 2% power loss.

The values in the table are based on Grundfos 50 W
solar modules (140 VDC output).
The table values are calculated on the basis of the
formula:
∆P q V ×
-------------------------------------------- ft [ ]
L =
×
Wp 100
where
L = Length of cable [ft]
∆P = Power loss [%]
V = Maximum power voltage [V]
mp
Wp = Watt peak [Wp]
ρ
= Specific resistance: 8.175 x 10
q = Cross-section of submersible drop cable [in
The sizing tool in WinCAPS makes it possible to calcu-
late the exact losses.
