High tension cables (also known as overhead power lines) are wires that are used to transmit electrical energy from one point to another. They consist of wires, typically made of copper or aluminum, which are bound together with insulating materials and installed at different heights above ground.

High tension cables are used to supply electricity to homes and businesses, and they also provide the backbone of major electrical grids. They are used in a variety of different applications, including power transmission, power distribution, and telecommunications.

High tension cables are typically placed at varying distances from the ground, depending on their purpose. They are typically installed on towers, poles, pylons, or other structures located along rights-of-way. In some cases, the wires are supported by suspension insulators, which are designed to reduce the risk of electric shock.

High tension cables are designed to handle a large amount of electrical energy, often over long distances. As a result, they must be made of durable materials and be able to withstand extreme weather conditions, such as high winds and lightning strikes. To reduce the risk of power outages, power lines are usually protected by lightning arresters and surge protectors.

High tension cables are used in many different types of electrical systems, including transmission lines, distribution lines, and telecommunications networks. In addition, they are also used in the construction of electrical towers and in the maintenance of underground electrical systems. Since these cables are essential components of electrical systems, it is important to ensure that they are installed correctly and will continue to function properly over time.
