CableNet + IEC 60364 calculations

From 1988 INTELEC collected a extended knowledge with IEC 60364 regulations and introduced the integrated CableNet program on the market (1993) in cooperation with Energy company NUON. The program includes extended databases Transformers (IEC 60076), UPS (IEC 62040), Cables (IEC 60228), Busbars (IEC 60439-2), Fuses (IEC 60269), Circuit Breakers (IEC 60898 and IEC 60947-2) and the IS-CAD symbols (IEC 60617), which are maintained by INTELEC on a regular base. The application is an extended electrical engineering tool for designing and managing electrical calculations for medium and low-voltage power distribution.


The integrated program has the possibility for defining the electrical network in a fast and efficient way. With connections and collections the installation can be extended. After the input the integral calculations can be exported and advanced reports can be generated. Critical parts of the installation can be analysed, selected and efficiently changed. With the available databases the engineer can also quickly generate new alternatives. The program now has become an indispensably tool for every electrical engineer. 

Integral CableNet-calculations according IEC 60364

The following integral CableNet calculations are included :

  • Cumulative Voltage losses
  • Voltage drops startup motors
  • Short-circuits (kA) (3-phase)
  • Touch voltage (1-phase short-circuit)
  • Cos-phi compensation (idle-current)
  • Analysis Selectivity

Further Specifications :

  • extended reviews for all data and calculations-results
  • analysis for the power distribution (asymmetrical- and nul-currents)
  • output of the installation-schemes (NEN-5152) and also DXF (CAD)
  • output of the short-circuit calculations (grafics)
  • calculation of the cable (summary of length and prices)
  • extended technical reports
  • integrated with IS-CAD (+) :

Computer Aided Design : IS-CAD (+)

TThe software also includes the IS-CAD (trial) program and the IEC 60617 library 2010, for extending and printing the generated installation-schemes. With the pro-version IS-CAD+ you can design and plot cable views, controller- and connection schemes and distributor-plans; import- and export DXF and PDF, scaling, the library manager and more ...

From 1988 INTELEC collected a extended knowledge with the IEC-60364 regulations and introduced the integrated CableNet program on the market (1993) in cooperation with Dutch Energy company NUON. Since that time the program grew dynamically and thousands of licenses have been sold.
