Commercial vehicles, such as electric trucks and buses, require heavy-duty electric vehicle (EV) charging depots with substantial, robust electrical infrastructure.

Unlike installations with relatively constant demand, these depots often experience peak demand at night, as trucks and buses return after operating hours and charge simultaneously for the next day.

This load variation must be assessed during design, as the cables experience short, high-load peaks followed by periods of lower loading.

IEC 60853 cyclic rating calculations account for the thermal behaviour of cables under varying load conditions, including:
• 𝗗𝗮𝗶𝗹𝘆 𝗹𝗼𝗮𝗱 𝗽𝗿𝗼𝗳𝗶𝗹𝗲𝘀 with periods of high and low charging demand.
• 𝗧𝗵𝗲𝗿𝗺𝗮𝗹 𝗶𝗻𝗲𝗿𝘁𝗶𝗮, which allows cables to withstand temporary loading above their steady-state ratings.
• 𝗣𝗲𝗿𝗺𝗶𝘀𝘀𝗶𝗯𝗹𝗲 𝗽𝗲𝗮𝗸 𝗰𝘂𝗿𝗿𝗲𝗻𝘁, determined without exceeding the cable's maximum allowable conductor temperature.

The Transient Ratings module of the 𝗘𝗟𝗘𝗞 𝗖𝗮𝗯𝗹𝗲 𝗛𝗶𝗴𝗵 𝗩𝗼𝗹𝘁𝗮𝗴𝗲 software enables engineers to model time-varying load profiles and calculate permissible peak currents in accordance with the standard.

By accounting for the cable's thermal response, engineers can assess safe peak charging loads and optimise cable sizing without oversizing the electrical infrastructure.

The reliability of telecommunication facilities depends not only on the equipment at the top of the tower but also on the overall installation, including essential safety systems such as the earthing grid.

Poor earthing can result in dangerous touch and step voltages, equipment damage, and service interruptions during electrical faults or lightning events.

The ELEK SafeGrid Earthing software enables engineers to model earthing systems, assess safety limits, and ensure compliance at telecommunication tower sites.

Vertical risers are often required to route power cables in high-rise buildings. Unlike horizontal installations, these risers have unique thermal conditions that directly influence the cable's current-carrying capacity.

Accurately determining riser cable ampacity is essential for correct cable sizing and safe operating temperatures, yet it depends on several factors that are difficult to assess manually. These include:
• Natural airflow and chimney effects within the riser
• Ambient air temperature surrounding the riser
• Outside wind speed, which affects heat dissipation through the riser wall
• Riser dimensions and material

Accounting for these factors manually is complex and error-prone.

The ELEK Cable High Voltage Riser/J-Tube installation module allows engineers to input the necessary parameters directly and perform accurate calculations. These include:
• Riser dimensions and material
• Cable construction (single-core or three-core)
• Ambient air temperature and outside wind speed

The software automatically evaluates the thermal behaviour of the installation and calculates the cable ampacity, helping engineers produce reliable designs while significantly reducing calculation effort.

Modern power systems increasingly depend on Battery Energy Storage Systems (BESS), particularly in networks integrating renewable energy sources that require grid stability and energy management.

BESS facilities use both AC and DC cable systems: DC cables connect the battery systems to power conversion equipment, while AC cables distribute power between inverters, transformers, switchgear and the wider network.

Given how critical these systems are, accuracy matters. Inaccurate thermal assumptions or parameters can result in:
• Undersized cables operating above allowable temperatures
• Unnecessary oversizing and increased project costs
• Reduced cable life and reliability
• Limits on the power the BESS can safely deliver

𝗘𝗟𝗘𝗞 𝗖𝗮𝗯𝗹𝗲 𝗛𝗶𝗴𝗵 𝗩𝗼𝗹𝘁𝗮𝗴𝗲 performs AC and DC cable rating calculations across the entire BESS facility, accounting for cable construction, installation arrangement, loading, soil and backfill properties, and surrounding thermal conditions.

Engineers can then assess cable operating temperatures and determine suitable current ratings for the different cable systems throughout the facility.

Mining facilities often include dedicated substations and distribution systems that supply high-demand equipment such as crushers, conveyors, pumps, ventilation systems and processing plants.

The cables feeding these loads must be sized for both the required load and the actual installation method. An inadequately rated cable can operate at excessive conductor temperatures, accelerating insulation ageing and reducing cable life.

IEC 60287 calculations can be challenging, especially when performed manually, as they require consideration of several factors, including:
• Buried cables, ducts and engineered backfills
• Multiple circuits and mutual heating
• Different soil thermal properties and ambient conditions
• Complex cable arrangements where heat dissipation is restricted

ELEK Cable High Voltage performs cable rating calculations in accordance with IEC 60287 or using the Finite Element Method (FEM), enabling engineers to build an accurate thermal model of the cable system and its actual installation.

Correctly rated cables help keep mining operations running at the required load within temperature limits, without unnecessarily oversizing critical distribution circuits.

High-voltage cable systems are often installed in ventilated tunnels where accessibility, maintainability, and effective heat dissipation are critical design factors.

A distinct feature of this installation is that the cable rating also depends on the forced airflow through the tunnel and the tunnel's thermal characteristics. Accounting for these factors properly is essential for accurate, optimised ampacity calculations in accordance with IEC 60287.

Hand calculations are impractical here. The process is iterative, requiring engineers to determine how cable losses interact with the thermal environment, tunnel geometry, thermal properties, and ventilation conditions simultaneously.

The 𝗘𝗟𝗘𝗞 𝗖𝗮𝗯𝗹𝗲 𝗛𝗶𝗴𝗵 𝗩𝗼𝗹𝘁𝗮𝗴𝗲 software simplifies this process with its dedicated 𝗩𝗲𝗻𝘁𝗶𝗹𝗮𝘁𝗲𝗱 𝗧𝘂𝗻𝗻𝗲𝗹 installation module. Engineers can simply input:
• Tunnel dimensions and depth
• Tunnel wall thermal resistivity
• Air velocity through the tunnel
• (𝘖𝘱𝘵𝘪𝘰𝘯𝘢𝘭) Inlet air temperature

The software then performs the IEC 60287 calculations, accounting for cable derating due to the tunnel's thermal environment. Engineers can obtain reliable ampacities faster, with less calculation time and greater confidence in the final design.

Data centres rely on robust electrical infrastructure that allows critical systems to operate safely and continuously, minimising downtime and interruptions. An effective earthing system provides protection not only for sensitive equipment but also for personnel.

During high-current earth faults, ground potential rise and hazardous touch and step voltages may occur. An effectively designed earthing grid helps manage these conditions while keeping touch and step voltages within acceptable limits.

ELEK SafeGrid Earthing software allows engineers to design effective earthing systems for critical infrastructure, such as data centres.

Calculate earth grid impedance and ground potential rise. Assess touch and step voltages. Support safer and more reliable infrastructure.

Remote offshore facilities are often supplied via high-voltage submarine cables from onshore supplies or other remote generation sources.

Unlike conventional cable system installations, submarine cables are exposed to complex thermal environments, with their current-carrying capacity influenced by a number of factors:
• Seabed thermal resistivity and burial depth
• Cable construction and electrical losses
• Burial or protection systems
• Nearby cables and mutual heating

Inaccurate assumptions can lead to cables operating at excessive conductor temperatures or, conversely, overly conservative ratings that restrict the amount of power that can be transferred. For submarine links running across vast distances, correcting an unsuitable design or installation after deployment is difficult and can be extremely costly.

ELEK Cable High Voltage provides a platform for accurate IEC 60287 assessment of submarine power cable capacity, accounting for these subsea thermal conditions.

By modelling the actual cable construction and its surrounding thermal environment, engineers can determine appropriate current ratings and identify thermal constraints before the cable system is installed, helping to avoid costly mistakes and unnecessary rework.

Battery Energy Storage System (BESS) facilities are becoming increasingly important in modern power systems and distribution networks, largely by supporting renewable energy integration, grid stability and reliable power supply.

However, BESS facilities involve high-power equipment, such as battery systems, transformers, inverters and switchgear. During an earth fault, high fault currents can flow through the facility's earthing system, potentially leading to hazardous touch and step voltages across the site.

High-touch and step potentials can expose personnel to dangerous voltages, particularly around equipment, metallic structures, and other accessible areas.

ELEK SafeGrid Earthing allows engineers to assess earthing system performance and design safer grid configurations by evaluating:
• Ground Potential Rise (GPR)
• Touch and step voltages across the site
• Earthing grid geometry and conductor arrangement

With accurate touch and step voltage calculations, engineers can refine their designs to reduce hazardous voltages and ensure they remain within applicable safety limits.
