## Modelling and Calculations

### model cables

Cableizer is suitable to model power cables of all voltage range, be it 230 V or 500 kV; AC or DC cables; one-, two- or three-core cables; with all kind of materials for conductor, insulation, screen/sheath, armour and jacket.

### cables in air

All options offered by IEC can be used, plus cables in pipes and grouped cables with solar radiation.

### buried cables

You can create laying arrangements made out of multiple cable systems of different cables, all having different frequencies and loading, plus multiple heat sources and sinks at the same time. You can also use rectangular duct banks and backfills of any size and drying-out of soil with multiple systems.

Additionally, a soil temperature calculator is available.

### ventilated tunnel

You can calculate the cable current rating for up to 4 different cable systems or heat sources in ventilated tunnels. The method is applicable to any type of cable.

The method is based on IEC 60287-2-3 but much extended, making Cableizer the only software in the market able to calculate different cable systems in ventilated tunnels.

### air-filled troughs

You can calculate the cable current rating for up to 4 different cable systems or heat sources in air-filled troughs.

In addition to the rather basic IEC method, you can choose from an additional five methods currently under discussion: IEC plus Anders 2010, IEE Wiring Regulation, Slaninka I, Slaninka II, ECRC Report 219 plus Anders 2010.

### subsea cables

You can calculate the cable current rating for a subsea cable including parallel heat sources.

The 2K criterion, established by German authorities as a precautionary measure to protect benthic life, can be considered. The 2K criterion is described in the book Submarine Power Cables by T. Worzyk (2009).

### 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.

You can define the temperature range manually.

### magnetic fields

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.

### multiple cable 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.

The method is based on IEC 60287-3-3 but much extended.

Cableizer is the only software in the market able to calculate multiple crossings using an itelligent iterative procedure.

### cable preview

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

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

### weight of cable

The cable editor calculates the total weight of the cable per meter. The weight of the metallic parts such as copper, aluminium and steel are shown as well as the weight of the 'empty' hollow cable.

This gives input for

• cable pulling calculation
• total weight of drums for transportation studies
• estimation of cost of cable

### cable pulling and dressing factors

The minimal bending radius is calculated based on diameter and insulation.

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.

### 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. Cableizer calculates the value automatically for each cable.

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 separately calculates the heat energy content for the insulation, screen bedding, screen serving, filler, and jacket of your cable.

### 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.

### cost of metals

The London Metal Exchange (LME) is the global platform for trading non-ferrous metals. So we take latest LME notations, 3-Month-Buyers, for a metric ton of copper (Cu), aluminium (Al), lead (Pb), zinc (Zn) and nickel (Ni).

Steel is traded many places and we use Shanghai Steel Rebar Futures for carbon sttel, traded in CNY, converted to USD. For stainless steel, we multiply by a factor 5.

Always, the latest official metal prices are taken, typically from the previous trading day.

### 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.

### 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 %

### 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.

### cable pulling

A cable damaged during installation can cause service failures. Mechanical stress during installation is generally more severe than those encountered while in service. With the help of Cableizer, you can prevent problems by calculating the maximum allowable pulling tension for any installation.

Calculations should be made to indicate 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.

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.

### 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.

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.

### 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 $μ$.

### cyclic and emergency calculation

You can calculate the cyclic load acc. to IEC 60853-2

As well as the emergency load (including graph)

### equations

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.
