 |
Main Characteristics : |
|
Two designs of ground substations have been developed, in accordance with IEC 61330, the choice being linked to constraints for upgrading the networks and their load.
- ECOBLOC, in which the LV board and operating cabinet are fitted directly into the transformer
- ECOPOST, is made up of equipment mounted in an enclosure. In the A version, it has a Protection and Disconnection Transformer (TPC) along with a fused LV board. Version B includes, in addition, monobloc MV equipment with a switch-disconnector and an earthing switch.

Additional Features : |
|
- Simplification of the management of supplies thanks to an improved customer relationship, from taking the order to installation of the equipment
- Reduction in purchasing and operational costs
- Better integration with the environment thanks to a discreet and compact architecture
- The integration of a Protection and Disconnection function in the transformer guarantees the total safety of the substation. In this way an efficient protection system is available, even if the supply is provided by a tangent box from an underground network. It acts efficiently in case of damage, or where the line impedance could hide the fault from distant fuses at ground-entry level.
