Several critical features of an overhead electric cable make it ideal for ‘in the air’ setups. Anyone who lacks electrical cable expertise may assume that any electrical wire is suitable for overhead installations.
#ARAUSIO THEATER OVERHEAD INSTALL#
So, in simple terms, an overhead cable is any cable that you can install above your head in the sky. Generally, the term ‘overhead’ means above the level of the head or in the sky. Do you intend to carry out any long-distance power or data transmission application? An overhead line cable will undoubtedly serve you better than any other cable type. This is especially important because the utmost valuable purpose of the wire is to transmit current over considerable long distances. Increasing the conductor’s diameter elevates the overall conductivity of the cable immensely. The primary reason for using a more prominent diameter conductor is that aluminium has a lower specific conductivity rate than copper. Nevertheless, it is necessary to recall that the construction of an overhead cable using aluminium demands a conductor with a bigger diameter. Consequently, it is more logical to use a cheap conductor that minimizes the cost of the cable. Generally speaking, an overhead wire is often used over extremely long distances. Secondly, aluminium is cheaper than copper. Logically, any stress on the utility poles will cause them to condescend, thereby lowering the overhead cable to an unsafe distance from the ground. Heavy cables would cause unfathomable strain on the utility poles, which are often wood-based. First, aluminium is lighter than copper, which makes it an ideal option for a strung cable. Why is aluminium used as an overhead cable?Īre you wondering why manufacturers use aluminium instead of copper, which is a better conductor of electricity? Well, the answer is pretty simple. If you intend to perform an extra-high voltage installation over a long distance, this cable type is ideal for you. It often comes in handy when dealing with electric power transmission over long distances.
The most common type of overhead cable is the bare aluminium cable.
As I indicated earlier, this cable type is strung high above the ground. Its popularity primarily stems from the fact that they are a less expensive alternative to underground cables.ĭissimilar to most electrical wires, an overhead electrical cable is made using aluminium. Unlike most electrical cable types, this cable type is common, especially in congested residential areas. In most instances, this electrical cable comes in handy when transmitting electrical power and data. What is an overhead electricity cable?Īn overhead cable is an electrical cable that is typically strung high above the ground using utility poles. Point to note: I wouldn’t be fair to you if I fail to mention that at the end, the article provides an insightful comparison between overhead and underground cables. For instance, what these cables are made of, whether they bear any significant risks, et cetera. This article seeks to give you answers to some critical questions concerning an overhead wire.Įssentially, this post seeks to provide expert guidance on everything concerning overhead cables. Like other electrical cables, there are several factors that you need to consider when choosing an ideal option. Unfortunately, finding one that suits your specific needs is a complex process. To gain access to them, you most likely need an overhead line cable. We all need electric power and information to live comfortable lives in today’s society. Considering that electricity and data carry significant value in modern-day society, you ought to be highly acquainted with an overhead power cable. Generally, this type of cable transmits data or electrical power across various residential buildings. We often see it meandering seamlessly above residential houses, yet we pay no attention to it. An overhead cable is arguably one of the most popular electrical cables.
