The Features of Good Electrical towers
An average electrical tower ranges from 15 to 55 metres in height. Many of them are made of steel and are known for their function of supporting numerous electric cables. The decision to make the towers using steel is based on the strength of steel and its ability to withstand adverse weather conditions.
It must be appreciated that some of the oldest electric towers are made of steel with maintenance being done only on routine basis. The base of the towers must be well done. In most cases, the towers will be made of the kind of foundation required for strong buildings with the foundations often being dug deep into the ground. This is to ensure stability and reduce the risk of the towers tipping over and causing loss to property and humans through electrocution and impact.
The points at which the electric wires meet the towers are always well insulated using some of the best insulators available globally. The electric towers must at all times assure the safety of the public by reducing the risk of electrocution. The maintenance of high heights is also necessary to ensure that there is not undue interference from vegetation. The towers can either be made of single tubular steels or of the lattice steel structures. The tubular steel structures are known to be much easier to construct and therefore much cheaper than the lattice steel structures. On the other hand, the lattice steel structures tend to offer a more stable base and therefore always hailed as more stable and more durable. They also have the capacity to host numerous electric cables without having to allocate some lines lower heights than could pose a threat to humans and vegetation.
The safety of the electric towers should be the main consideration that must come before cost and preferences. This is due to the fact that electric cables possess a capacity to cause great damage to property and may even lead to loss of life.
