Pressurized air cables and GIL

You can model pressurized air cables (PAC) like Hivoduct or gas insulated lines (GIL) like Siemens. PAC/GIL can have hollow or solid conductors of different materials, a gas compartment with pressurized dry air, Nitrogen (N2), Sulfur hexafluoride (SF6), CO2 Carbon dioxide (CO2), or gas mixtures, plus a metallic enclosure and a protective cover.

PAC/GIL can then be used in air, buried, in tunnels, and now also in troughs.

Buried cables

FEM multilayer backfill

With the multi-layer backfill method, it is possible to simulate the filling of a rectangular trench where the cables are buried with two superimposed horizontal layers of different materials, stacked above the cable bedding, respectively duct bank.

Learn more about the method used, its range of validity, and its validation in our blog post.

FEM multilayer backfill

Multiple cables in duct

You can place up to 12 cables inside the same duct.

Their position inside the duct is automatically set depending on inner duct diameter.

Temperature field

You can calculate the temperature distribution in the soil and show the increase in temperature due to power cables or heat sources/sinks.

NEW Temperature field now possible also for modules tunnel and trough. Several new settings are possible such as plot width, isolines and colormap. The temperature field can be plotted using finite element method including heat flow inside cables, ducts and inside troughs and tunnels.

Soil temperature distribution

Magnetic field

You can calculate the magnetic field of multi-frequency systems, set the load flow or a phase-shift for each system. The output is in brilliant 2D isolines and in 1D lines above ground.

NEW Magnetic field calculation is now possible for all modules: in air, buried, subsea, tunnel, trough, and riser. Several new settings are possible such as plot width, isolines and colormap.

Magnetic fields

Multiple crossings

You can calculate the crossing at any angle of one or multiple cable systems with one or multiple other cable systems or heat sources.

Cableizer was the first software in the market able to calculate multiple crossings using an intelligent iterative procedure. The method is our own develpment and was presented at Jicable'19 in Paris. Download the full paper at researchgate.com

You can calculate the cable current rating for multiple different cable systems or heat sources in empty or filled troughs.

Choose from five methods: IEC 60287, IEE Wiring Regulation (BS 7671), Slaninka I with all equal resistivities, Slaninka II with different resistivites, or Anders extending Slaninka II for empty (air-filled) troughs.

We introduced cyclic rating in air-filled troughs based on a method by L. Heinhold (1999) and an analytic method acc. Endacott for filled troughs.

Cables in empty and filled troughs

Submarine cables

You can model three-core submarine cables with with jacket around each core. The calculation is based on the Jicable paper 'Thermal analysis of 3-core SL-type cables with jacket around each core using the IEC standard' by L.D. Ramirez et al., dated 2019.

The sheath jacket thermal resistance and it's thickness can be set independent from the filler.

Submarine cables Submarine cables


You can calculate the cable current rating for a subsea cable including parallel heat sources. The subsea cable can be fully buried, partially buried and completely in water. Calculation method can be chosen between IEC (only buried), Carslaw & Jaeger, Morud & Simonsen, Ovuworie, or OTC 23033

The heat increase at specific depth can be calculated to consider the 2K criterion.

Subsea Cables

Riser / J-tube

You can calculate the cable current rating for cables installed in J-tubes with four different methods:

  • Empirically method by ERA (1988) for risers sealed at top and bottom.
  • Analytical method by Hartlein & Black (1983) based around a thermal network model.
  • Extension to Hartlein & Black by Anders (1996).
  • Extension to Hartlein & Back by Chippendale et al. (2017) for J-tubes only.

Cable preview

Cableizer uses sofisticated code to visualize the cable in a 2D and 3D model and to update instantly after changes in the editor.

The dimensions of both previews are to scale for each layer relative to the others.

Cable pulling and dressing factors

The minimal bending radius is calculated based on diameter and cable type.

The maximum admissible pull force is calculated based on the conductor material and cross section using a factor. This factor may differ in other countries.

Cable heat of combustion, table

Heat of combustion

The gross heat of combustion value - also known as energy value or calorific value - is used to quantify the energy content of a cable in case of a fire.

The heat energy content is calculated as a product of the mass per meter and the heat of combustion value per kg for all non-metallic materials.

Cableizer calculates both values per layer and in total.

Cable heat of combustion, table

Embodied energy & CO2

Embodied energy is the amount of energy consumed to extract, refine, process, transport and fabricate a material or product. It is often measured from cradle to factory, cradle to use, or cradle to grave (end of life).

Likewise, embodied carbon footprint is the amount of carbon (CO2) emission to produce a material.

Embodied energy and carbon, table

Cost of metals

We calculate the cost of metals based on the latest available official metal prices.

The London Metal Exchange (LME) is the global platform for trading non-ferrous metals which we use copper (Cu), aluminium (Al), lead (Pb), zinc (Zn) and nickel (Ni). Steel is traded many places and we use Shanghai Steel Rebar Futures.

Cost of metals, table

Short-circuit currents

The short-circuit rating of any current carrying component of a cable - conductor, screen, sheath and armour - is calculated according to the standard IEC 949, taking into account non-adiabatic heating effects.

Initial temperature is taken from the ampacity calculation results directly to ensure worst-case scenario.

Short circuit currents

Voltage drop

For the calculation of voltage drop along a cable, one may enter a specific load (kW), the power factor (cosφ), and the length of the cable line. The power factor is the ratio of active power to apparent power and when the waveforms are purely sinusoidal the phase angle φ between the current and voltage.

If possible, the voltage drop is calculated for a range of 0 to 15% voltage drop. The voltage at the given length is visually highlighted and the value written in kV and %

Voltage drop

Critical length

A figure can be drawn where the active power at the load point versus the length of the line is presented (assuming cosφ=1).

With increasing length, the capacitive charging current will reach the value of the maximum allowable current of the cable, so the charging current accounts for all the available heat losses in the cable and the active power reaches zero. This length is called the critical length.

Critical length

Cable pulling

Calculations of the pulling tension should be made whether the pull looks easy or impossible, making the decision to pull an obvious choice. With Cableizer you can easily model the cable route with sections, slopes, bends and cable pushers including a fantastic 2D and 3D preview.

In addition to a table we produce a plot of the pulling force along the route. You can even calculate dynamically the pulling forces of cables being pulled over a route longer than the cables.

Solar radiation calculator

The solar radiation calculator is a tool that estimates the intensity of solar radiation for a given day and a given place depending on its location and altitude. The calculations assume clear weather conditions and assume that the location is not shaded. Enter the latitude and altitude of the location or select the values directly from google maps.

Solar radiation curves

Soil temperature calculator

The soil temperature calculator helps you to estimate the ambient soil temperature at a particular lying depth and day of year. In climates with distinct seasons one observes temperature changes in the uppermost soil meters. The upper soil layers are heated in the summer, while the deeper layers are still cold and while the heat propagates downwards, air temperatures are already dropping again.

Load factor

The Load Factor Calculator is a tool that calculates the squared ratio between the average power $D_{average}$ and the maximum demand $D_{max}$ in a period of time.

$$LF=\frac{D_{average}}{D_{max}}=\frac{I}{D_{max}} \frac{\sum\limits_{t=0}^T D(t)dt}{T}$$

It is used for cyclic loading calculations acc. to Neher McGrath. With a subscrition you can even calculate the loss factor μ from your load profile and use it for transient calculations.

Load factor

Loss factor

The Loss Factor Calculator is a tool that calculates the ratio between the average power losses $L_{average}$ and the losses during peak load $L_{max}$, in a period of the time. In other words, the loss factor is simply the load factor of the losses.

$$\mu=\frac{L_{average}}{L_{max}}=\frac{I}{L_{max}} \frac{\int\limits_{t=0}^T L(t)dt}{T}$$

It is used for cyclic loading calculations acc. to IEC 60853. You need a subscrition to calculate the loss factor µ.

Equations can be included in the calculation reports and the cable datasheets. Where multiple cases with different formulas exist for a certain parameter, the software always takes the exact formula which was used for the specific system and cable.

We don't use pictures, we actually write the correct and complete formula. For all steps!

Same for our open source documentation where every parameter can be found with description, formula, unit, standard values, and linked references.
