Leakage capacitances
11.6.1
Leakage capacitance of power cables
The "RKL" series power cables (bulk cables) from Rexroth have the following
capacitances per unit length. The values refer to the sum of the individual ca‐
pacitances of power cores 1, 2 and 3 against the overall shield.
See also Rexroth connection cables - bulk cables data sheet.
Leakage capacitance is specified in C per cable. In the case of parallel con‐
nection, the total value is the sum of individual cables.
