Do electrical constraints preventyou to achieve your lightingprojects such as roads,motorways, sites ? Are you stopped by LowVoltage limits ? YOURS CONSTRAINTS : No availability of electrical sources closed to the course to light ; the lowvoltage is quickly limited OUR SOLUTIONS : Only one electrical source and one energy transport in 3200V or 5500V. > 60 11381 - 31/05/07 size="-2">

From only one Low Voltage (400 V) or High Voltage (20 KV)electrical source , we advise you to create a MV voltage which allows the energy distribution along the course on average and long distan-ces (from 2 to 20 Km). > We study with you and for you all the design of the step-up or step-down cabinet. We are a manufacturer of this kind of systems MV sourcesӔ: 3200 or 5500 V. This Voltage is transported by adapted cable (6 kV). Transformers burriedclosed to the lighting column restore the LV voltage 230 V or 400 V.We produce those transformers, real step-down mini-station˻.Thosecable and...
