1 MEDIUM VOLTAGE For your projets where the low voltage is limited 3200V 5500V 6600V Energy distribution

YOUR EXISTING CONSTRAINTS Example 1: FROM LV EXISTING ELECTRICAL SOURCES : Transport the LV to the cabinets LV Cabinet LV Cabinet Long distance LV Source Town Ind.

2 YOUR EXISTING CONSTRAINTS Example 1: FROM LV EXISTING ELECTRICAL SOURCES : Transport the LV to the cabinets LV Cabinet LV Cabinet Long distance LV Source Town Ind. Area Crossing of property LV Cabinet LV Source Is this feasible? Will you find these sources in the vicinity? What will be the cost of large cross-section cable which will carry energy to the course? Will it be easy and cheap to manage the administrative formalities and the authorizations? Example 2: FROM A HV ELECTRICAL SOURCE : Creation of a HV and LV network. Town Ind. Area T T T HV Source HV / LV transformers Is this feasible to transport the HV along the course? What will be the cost? Do you control the deadlines? Isn t it luxurious for a simple lighting?

YOUR VOLTAGE BECOMES : Medium Voltage This solution brings

33 kv) electrical source, we advise you to create a MV which

design of the step-up or step-down cabinet.

Transformers burried closed to the lighting column restore

We produce those transformers, real «step-down mini-station».

4 YOUR VOLTAGE BECOMES : Medium Voltage This solution brings the autonomy of study, of work and of work management at an undervalued total cost. From only one Low Voltage (400 V) or High Voltage (11 kv - 33 kv) electrical source, we advise you to create a MV which allows the energy distribution along the course on average and long distances (from 2 to 20 km). MV LV or MV Source 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 sources» : 3200 V, 5500 V or 6600 V. This voltage is transported by adapted cable (6kV). Transformers burried closed to the lighting column restore the LV voltage 230 V or 400 V. We produce those transformers, real «step-down mini-station». Those cables and transformers will be installed by your contractor. The MV allows you autonomy with a reduced budget from 15 to 30% but will also bring you the possibility to add other advantages : - To forecast future extensions - To save energy at rest time - The telemanagement by STEP All relative procedures and rules are respected

For information : In a project, 2 step-up stations can be replaced by one step-down station.

7 ROAD LIGHTING INDICATIVE TABLE TO CHOOSE THE TRANSPORTATION VOLTAGE Cross-section of calculated for a drop voltage of : 5% for 950 V network, 3% for 3200 V and 5500 V network. Power rating uniformy spread. For information : In a project, 2 step-up stations can be replaced by one step-down station. In each case, possibility to add an energy saver dimmer : -For the step-up cabinets : the compacto dimmers. -For the step-down stations : THR 550 from160 to 630 kva
