IEC 60502 Standard

Medium Voltage Power Cable Sizing per IEC Standard
ETAP IEC 60502 Medium Voltage Cable Sizing offers a comprehensive and integrated software for conducting cable current carrying capacity, voltage drop, fault rating and cable power loss calculations in compliance with the latest IEC 60502.
IEC 60502
The IEC 60502 standard applies to extruded insulation power cables rated from 1 kV to 30kV for underground and above ground applications. 
  • Quickly & accurately calculate cable sizes
  • Integrated with load flow, short circuit & protective device coordination modules
  • Simulation & alerts based cable size adequacy using 'what if' scenarios
  • Intelligent cable current carrying capacity assessment & temperature correction
  • Current carrying capacity evaluation for various cable layouts
  • Extensive MV cable libraries from various manufacturers

Cable Raceway Installations

  • A/G Trays (perforated)
  • Ladder
  • U/G Duct
  • U/G Buried
IEC 60502 Cable Raceway Installation and Layout

Cable & Tray Layout

  • Flat layout – Touching or Spaced
  • Trefoil layout Touching or Spaced
  • Horizontal layout
  • Vertical layout
  • Number of Trays
  • Circuit Clearance
  •  Depth of Laying

Alert for Allowable Capacity

The alerts can be set based on the options listed below:

  • Calculated cable capacity
  • User-defined value
  • Thermal analysis results of underground raceway systems

Grouping Factors

The cable capacity simulation program for above ground (trays and ladder) and underground (duct and buried) calculates the current carrying capability of a cable based on number of circuits as limited based on the standard.

Soil Resistivity & Temperature Correction

The soil thermal resistivity is an important thermal parameter for underground installations. ETAP computes the cable capacity based on the ambient and conductor temperatures. In addition, the user can enter the actual operating temperature of the cable and the current carrying capability will be adjusted accordingly.
