THE ADVANTAGES OF INTEGRATED SOLUTIONS FOR TURNKEY MARKETS

摘要

For several years, suppliers of high-voltage equipment for outdoor substation have been offering integrated solutions combining all the equipment for one bay within single equipment. These innovative solutions are either air-insulated with AIM or MCI, or SF{sub}6 gas insulated with OPTIGIS or TH7h. The main advantages of these integrated equipment have been reported many times: financial gain due to the concentration of functions in a single equipment and the possible mutuality of certain parts (support, electrical insulations, low voltage, etc.), undeniable space-savings leading to additional price reductions and ease of installation. It is important to check that the integrated equipment are suitable for the rehabilitation of bays and provide gains compared with traditional solutions. The advantages provided by the integrated equipment for complete reconstructions, which can be competitive compared with rehabilitations, should be taken into account. This article is an exchange between an utility and two manufacturers, in order to compare the utility's needs and concerns with the solutions offered by the manufacturers.
