High Tension Cables
High tension or High voltage cables if specially designed power cabled that is used to transfer high voltage electricity. High tension Cables are made up of several layers that work together to transfer electricity and protect cable from high voltage and environmental factors.
- Conductors: Made from copper or aluminum, conductors carry the electric current. HT cables typically use stranded conductors to enhance flexibility and reduce resistance.
- Insulation: Insulation material, such as cross-linked polyethylene (XLPE) or ethylene propylene rubber (EPR), surrounds the conductor to prevent electrical leaks and withstand high voltages.
- Shielding: A metallic shield (usually made from copper or aluminum) around the insulation reduces electric field stress, provides grounding, and enhances safety.
- Outer Sheath: The external covering protects the cable from moisture, corrosion, mechanical damage, and environmental factors. Common materials include polyvinyl chloride (PVC) and polyethylene.
- Additional Layers: Some HT cables include a semi-conductive layer between the conductor and insulation, which helps distribute the electric field evenly and enhances durability.
Advantages of High-Tension Cables
-
Efficient Power Transmission: By carrying high voltages, HT cables minimize energy losses over long distances, making them ideal for transmitting power from generation plants to urban areas.
-
Enhanced Durability: With robust insulation and outer sheathing, HT cables are resistant to extreme temperatures, moisture, chemicals, and mechanical stress, ensuring long-term reliability.
-
Space Efficiency: High-voltage cables reduce the need for multiple low-voltage cables, saving space in crowded installations.
-
Safety: The multi-layer structure and robust insulation reduce the risk of short circuits and electrical hazards, ensuring safe operation in high-voltage environments.
