Optimize Your Power Cable Infrastructure
Use Grøft Design® Software to correctly dimension cables, minimize failures, and optimize cable utilization with easy to use ampacity calculations
The cabels for a 3.5 MW EV charging depot using traditional steady-state were running hot. In this case study, by applying time-variable load analysis with real charging patterns, we found actual cable temperatures stay well within safe limits.

Drying of cable backfill soil is becoming a real problem. Dry soil reduces heat transfer away from the cable, Consequently, as the soil dries out, the current-carrying capacity of power cables (ampacity) decreases.
