Exploring EHV Cables and Their Applications

 


Ideally, extra high voltage (EHV) cables are designed to handle extremely high voltages. This voltage range typically begins at 66 kV and can exceed 220 kV, with some applications extending up to 400 kV.

The goal is to transmit large amounts of power with minimal losses.

Most EHV cables use copper or aluminum conductors. The commonly preferred insulation material for these cables is XLPE, thanks to its excellent electrical properties and high thermal resistance.

Applications of EHV Cables

Power transmission and distribution utilities: EHV cables are used to carry large amounts of power from where it is generated to substations located over long distances. In simple words, from power plants to substations. Also, these cables help distribute electricity from substations to various sectors like industrial, commercial, and residential areas.

Mining and processing industries: EHV cables are ideal for the power requirements of mining operations of critical minerals. They also make a perfect choice for processing plants for rare earths or other critical minerals.

Steel and other metal industries: These cables find applications in power intensive steel processes as well as production of other metals.

Oil and gas industry: EHV cables are used in transmission and distribution of power for oil and gas exploration, refining, and transportation.

Airports and railways: EHV cables are used to supply power to large facilities like airports with high power demands. In some railways, these cables power electric locomotives and signaling systems.

Renewable energy installations: These cables play an important role in the production of clean energy. They transmit power generated from renewable sources like wind and solar farms to the main grid.

We recommend installing EHV cables underground to protect them from environmental stress. The other benefit of this practice is that it reduces visual clutter often created by overhead cable lines.

Not only it keeps the surrounding clean and organized in urban residential areas, but also in environmentally sensitive zones.

Therefore, EHV cable systems require careful design and proper route selection to ensure safe and reliable operations. This helps protect cables from damage and prevents their interference with other underground services.

Exploring How Cables Power Battery Energy Storage Systems

Image
  Battery Energy Storage Systems (BESS) are one of the major stakeholders in the global energy transition goal. BESS is a rechargeable energy solution that enables electrical energy to be stored for use in the future. It reduces overreliance on grids and keeps their stability intact. It also helps in optimizing the energy usage and efficiency of various applications. In this blog, we learn about BESS facilities and the role of cables in establishing a reliable transmission setup. How BESS Facility Works BESS is usually integrated with on-grid and off-grid systems. Charging phase: When electricity from a grid or a solar panel flows into the system, batteries store this energy by converting it into chemical form. Discharging phase: When the source stops energy production, the BESS discharges and powers homes by converting the stored energy back into electrical energy. The main benefit of BESS is that energy stored during low-demand hours can be used when demand spikes. Applications ...

Exploring Challenges Behind Submarine Cable Installation and Repair

Image
  Think of the toughest jobs in the world. Laying and maintaining cables deep underwater is one of them. These cables are essential lifelines of global communication, facing extreme marine conditions, complex logistics, and inevitable geopolitical hurdles. Each installation or maintenance challenge demands planning and precision. In this blog, we try to understand these obstacles and highlight the hidden efforts put in by marine engineers, cable ship crew, remotely operated vehicle (ROV) operators, and others behind our seamless digital connectivity. Obstacles Faced by Submarine Cables Installation Challenges Cables of thousands of kilometers are exposed to underwater conditions such as strong currents, rough seaband terrain, and extreme pressure. And as the depth increases, the difficulty levels also increase, sometimes exceeding 10K meters where there is immense pressure and almost freezing temperatures. Specialised ships equipped with the dynamic positioning system are used to l...

What Are Single Core Cables?

Image
  Single core cables come with only one electrical conductor shielded with an insulating layer. This means it will be either a single copper or aluminum conductor. In comparison with multicore cables, cables with one conductor are more efficient. They can withstand harsh weather conditions, making them ideal for high voltage applications. Let us explore their benefits and applications in this blog. Benefits of Single Core Cables The following are some benefits of single core cables: Single conductor design: Since it is just one conductor, single core cables have the simplest design and construction. They create one path for the current to travel. These cables provide smooth connections and terminations, ensuring optimal performance of electrical systems. High current carrying capacity: Cables with just one conductive core can be arranged with better spacing from other single core cables. This extra spacing allows for better heat dissipation and reduces risk of overheating. As a res...
