High-voltage cables are specifically designed to transport electricity at elevated voltages. These cables consist of a conductor surrounded by a complete insulation system, which includes layers of insulation, metallic shielding, and semi-conductive materials. Depending on their application, these cables can vary significantly. Some are used in ignition systems, while others are utilized in AC and DC power transmission. Regardless of their intended use, high-voltage cables face challenges such as insulation degradation caused by high-voltage stress or ozone generated from electric discharges. To ensure safety, objects and individuals should avoid direct contact with these cables, and measures must be taken to manage leakage currents. Additionally, cable joints and terminals should be engineered to control high-voltage stress, thereby preventing insulation wear and tear.
When installing such cables, the required length can vary based on the project's purpose. For instance, shorter lengths are typically sufficient for equipment wiring, whereas longer lengths are often necessary for transmitting power across vast distances, such as underwater. Furthermore, maintaining proper insulation becomes crucial when dealing with increased voltage levels.
Applications of High-Voltage Cables
High-voltage power cables are unique and are commonly found in switching and distribution panels. They play a vital role in enabling remote or manual control of individual supply systems during testing. These cables are also integral to triple extrusion systems and are used in environments where workers interact closely with machinery. High-voltage cables are employed in power circuits where the line-to-ground fault current remains within the shield's capabilities. They are installed in both dry and humid settings, including cable trays, ducts, and raceways.
At KEI, the team adheres to German engineering principles while manufacturing cables up to 220KV. These cables are meticulously crafted according to IS: 7098 Part II & Part III specifications. The entire development team focuses on meeting international standards like SABS, VDE, IEC, and NFC. For water-resistant cables, KEI incorporates sheaths made from stainless steel, lead, corrugated aluminum, corrugated copper, or polyethylene laminated aluminum tape (APL). To protect against rodent and termite damage, these cables feature polyamide/Nylon jackets or jackets treated with cypermethrin, ensuring anti-termite properties.
There are numerous reasons to choose high-voltage cables. Firstly, they are manufactured with triple-layer extrusion, utilizing XLPE or EPR insulation and a semiconducting bonded conductor screen over the semiconducting layer. This approach enhances the cable's lifespan and minimizes the risk of breakdowns. XLPE insulation also improves mechanical and electrical performance while reducing the dielectric factor.
It’s essential to prioritize cable quality when laying them underground for power transmission. Purchasing the appropriate type of cable ensures durability and resistance to extreme weather conditions. For industrial setups, maintaining a detailed inventory of cables helps track maintenance schedules and repair needs. Regular inspections by experts can prevent unexpected outages, which could otherwise disrupt operations and daily activities.

High Voltage Power Cables and Their Uses
When you encounter a warning sign near a transformer, it serves as a reminder to stay clear of the high voltage. Transformers pose significant risks due to their large cables carrying high voltage electricity. High voltage refers to levels exceeding a specific threshold, which can cause sparks in the air and deliver electric shocks if approached. As you continue reading, you’ll gain deeper insights into high voltage cables and their practical applications.
