Towers or power pylons have belonged to the landscape for virtually 100 years, yet how much do you understand about them? Below we bring you a few truths you never learnt about these legendary steel structures.
- There’s more to how power pylons function than meets the eye
Pylons are utilised to sustain electrical wires that transfer High Voltage Electric service where it’s produced, such as a wind ranch or power plant with the power system to our houses, as well as businesses.
Electrical power appears in a power plant at a lower voltage, about 10 to 30 kilovolts. Then it travels through a ‘boost’ transformer at a transfer substation to develop high-voltage electrical power, up to 400,000 volts which travel around National Grid’s electrical energy network. Enhancing the voltage enables higher efficiency with less energy loss. ‘Terminal’ towers lie at each end of the course, while angle or pressure towers make it possible for the course to be straightened if necessary.
Insulators made from unbreakable glass and porcelain sustain the above high-voltage cables and keep them far from the unearthed towers.
- Words pylon originates from the Greek term Pyle for ‘gateway’
Pylons, in ancient Egypt, were the outstanding obelisk-shaped pylons on both sides of the doors to holy places. Egyptology was popular in the Twenties, after the discovery of Tutankhamun’s tomb, as well as the child king’s mummy in 1922. Also, these were the years when the initial steel towers were erected, as well as they eventually now are the gateways to electrical energy for everybody.
- The design for pylons was the winning entry in a competition run by the Electrical Energy Board in 1927
Leading architect Sir Reginald Blomfield gets the credit rating for the ‘lattice’ style, which was intended to be extra fragile than the brutalist frameworks used in Europe, as well as the United States. However, the winning layout, which still strides throughout our landscape today, was submitted to the competitors by the Milliken Brothers, a design business based in the US, and chosen by Blomfield, the designer of London’s Lambeth Bridge.
- T-pylons, the first new style for pylons in over 100 years, are under construction currently
This new shorter, sleeker pylon style was picked from 250 access worldwide competitors arranged by National Grid.
The T-shaped pylon originates from the Danish company Bystrup as well as measures 114ft, or 35 metres, high. It’s about 50 feet shorter compared to the traditional metal lattice framework but can transmit still 400,000 volts.
The initial operational T-pylons are going to bring low-carbon electricity along the 35-mile path C electricity station to several homes and organisations.
