with a capacitance of 40-80pF/m within an industrial environment.
For an office environment, ABB recommends a minimum cable gauge of 0.14mm

,
and a capacitance of 40-100pF/m. Use a shielded cable in a heavy industrial
environment and an unshielded cable in an office environment. A shielded cable is
often given a higher capacitance and will therefore provide a higher data
transmission speed.
