Thermal Ampacity Calculations for Power Cables

In order to cater to the growing demands of our customer’s we undertake the following services:

Performing ampacity and temperature-rise calculations for power cable installations. Determining the maximum current power cables is important for the design of electrical installations can sustain without deterioration of any of their electrical properties
Steady-state and transient thermal cable rating as per the analytical techniques described by Neher-McGrath and the International Standards IEC 287© and IEC 853©
The Duct Bank Optimization allowing the user to determine the optimal placement of several circuits within a duct bank.
Calculating the magnetic flux density at any point on above the ground or an underground cable installation.
The Cables Impedance Calculations (ZMat) necessary for designing electrical parameters for cables necessary for performing load flow and short-circuit studies at the power frequency (50/60 Hz).
Calculation of thermally permissible short-circuit currents, taking into account non-adiabatic heating effects.
Modelling of two circuits crossings each other in the same installation.
Circuits crossing directly buried underground, in buried ducts and in buried pipes underground.
Short-circuit ratings computation for all metallic layers
Design Calculations for laying cables in different environments as:
- Multiple Duct Banks and Backfills
- Cables in Tunnels
- Cables in Troughs
- Multiple Casings

Computation of the sequence impedances for all the cables present in an installation
Computation of the sequence admittances for all cables present in an installation
One or more neutrals can be represented and are taken into account in the calculations
