FAQs
An overhead cable is a type of cable suspended high above the ground, typically on telegraph poles, commonly used for transmitting power and data. Unlike underground cables, overhead cables, often made of aluminum, leverage air for insulation, requiring less insulation material. This cost-effective alternative is popular in crowded residential areas, with bare aluminum cable being a common type, particularly suitable for long-distance power transmission. Selection criteria include electrical conductivity, tensile strength, and total cable density.
Overhead cables are typically supported by lattice-type steel towers or pylons, serving as carriers for high-voltage lines. In remote regions, helicopters may be employed to install aluminum towers for cable support.
Underground cables, buried with trenching, remain hidden, minimizing visual impact and weather effects. They often need extra insulation and demand more complex maintenance. Although installation costs are higher, maintenance is lower. In contrast, overhead cables, suspended on poles, are visible and more prone to weather. They leverage air for insulation, facilitating easier inspection and maintenance, with lower installation but higher ongoing costs. Underground cables suit urban and sensitive areas, while overhead cables are cost-effective in rural and crowded zones.
