The Trusted Solution
O’HARA ENGINEERING SERVICES is a major service provider in relation to the construction of 110kV Sub-Stations in Ireland. The most common of these sub-stations are Air Insulated Subs-Stations. AIS Stations are the tried and trusted method of distribution and transmission across most of world. The technology used has a design life of 35 years and in many cases there is AIS switchyards across Europe providing service after 45yrs. The major advantage of an AIS Sub-Station over and above other types of sub-station is the fact equipment in the stations is interchangeable. Different manufactures can be used to supply the various devices within the station. An example of this would be an ABB Disconnect feeding a surge arrestor manufactured by Areva which in turn feeds a transformer by CG Global. The advantages that this brings is two fold. In the rare cases where a piece of equipment fails replacement is quicker and easier than that any other type of station. The second advantage is that as technology develops the customer can have the best of both worlds with best surge arrestor technology by one manufacturer coupled with the best transformer technology from another. |
