Power stability can be controlled by high-voltage power cables

Insulation will deteriorate due to high-voltage stress or ozone electric potential discharges, regardless of where high voltage electric cables are used.

When you see a warning sign outside a transformer, it can mean that you should avoid high voltage. Because of the large cables, it is dangerous to approach the transformer. Because high voltage is the amount of power above a certain threshold, it can cause sparks in the air and electric shocks if someone comes too close to the transformer. As a result, as you continue reading, you will learn more about high-voltage cables and their applications.

What Are HV Power Cables? 

When you see a high-voltage cable, it is used to transmit high-voltage power. The cable is completely insulated and has a conductor. This means that these cables have a fully rated insulated system that includes insulation, a metallic shield, and semi-conductive layers. Such cables, on the other hand, will vary depending on the application. Some are used in ignition systems, while others are used in AC and DC power transmission.

However, regardless of where high voltage electric cables are used, insulation will worsen due to high-voltage stress, or ozone electric potential discharges. While no objects or people should come into contact with the cable system, they must be capable of controlling leakage current. Furthermore, the cable joints and terminals must be designed to control the goal of controlling high-voltage stress in mind. This can eventually help to keep the insulation from deteriorating. The cut length of these cables may differ depending on the purpose. When using cables for an apparatus, the length of the cables is not very long. However, when used to transmit power across an ocean, the cut length of such cables can be quite long. When the voltage increases it will be necessary to regulate the insulation.

When Do People Use a High Voltage Cable? 

Because HV power cables are unique, you will see them with switching and distribution panels. These cables also allow for remote as well as manual control of rooms while testing the individual supply systems. Such cables can be found in triple extrusion systems and when people work closely with raw materials. In the long term, such cables will be used in electrical loads where the line to ground fault current falls within certain shielding capabilities. Such cables are even installed in cable trays, ducts, and raceways in both dry and humid environments.

KEI team embraces German technology while producing cables up to 220 kV. These cables are always designed in accordance with IS: 7098 Part II & Part III specifications. The entire development team also works to design the cables in accordance with standards such as SABS, VDE, IEC, NFC, and others. When it comes to water resistant cables, KEI creates a high-voltage electric cable with sheaths made of stainless steel, lead, corrugated aluminium, corrugated copper or Polyethylene Laminated Aluminium Tape (APL). However, to prevent damage from rodents and termites, these cables have a polyamide/ Nylon jacket or a jacket with cypermethrin that provides anti-termite protection. 

There are numerous reasons why you should use high voltage cables. To begin with, such cables are made using triple-layer extrusion. During the manufacturing process, the team employs XLPE or EPR insulation, as well as a semiconducting bonded conductor screen across the semiconducting layer. This extends the life of the cables and reduces the likelihood of failure. When the team uses XLPE insulation, it improves mechanical and electrical performance while maintaining a low dielectric factor. Finally, when laying down high voltage cables for underground power transmission, it is critical to inspect their quality. When selecting the right type of cable, you must also consider its durability and ability to withstand extreme climatic conditions. If you are installing cables for industrial use, you must keep a cable checklist. Once you have a repository, you will have a better understanding of the repairs and the time required for maintenance. You should always seek the assistance of a professional for repairs or to thoroughly inspect the cables. By periodically inspecting the cables, you can reduce the occurrence of unneeded outages. However, if something unexpected happens, it can disrupt systems and daily operations at the location. KEI provides high voltage cables with the following special features based on site installation requirements: As previously stated, cable designs with corrugated aluminium sheath (CAS), corrugated copper sheath (CCU), corrugated stainless steel sheath (CSS), lead alloy sheath (LAS), or Polyethylene laminated aluminium tape (APL) are ideal for laying in water and moisture-prone environments. Low Smoke and Halogen (FR-LSH) and Low Smoke, Zero Halogen (LSZH) MV Cables: Cables subjected to fire are constructed with the above material for full safety in stringent places like hospitals, cinema halls, shopping malls, tunnels, airports, the intermittent or continuous presence of flammable gaseous materials, and so on. Rodent and Termite Resistant MV Cables: Cables are designed for robust protection needed to block rodents and polyamide / Nylon jackets to provide anti-termite protection.
