The distribution of electricity is the last stage in the delivery process. After production, processing and transmission, it is carried through a system of aerial and underground networks until reaching the end-users. Generally, this network includes medium voltage power lines "MV" (between 3 and 30 kV) and low voltage lines "LV" (up to 1,000 V in Ac), HV/MV transformation plants, transformers on poles or medium voltage electrical substations, disconnectors and switches, measuring instruments. The high-voltage "HV" lines (between 30 and 380 kV) are instead part of the transmission network that powers the national electricity distribution network.
The task of analyzing the levels of tension to adopt in the design phases in all the many situations and taking due account of the regulations and laws in force in each specific country of destination, is, as always, up to the designer.
ACTIVITIES ARE DIVIDED INTO:
- Transformer substations MV/LV.
- Systems for the transport and distribution of electricity in Medium and Low Voltage.
- Power Center-type distribution panels, with In at the busbar up to 4,000 A and forms of segregation at 4 B.
- Panels for the control of electric motors, type MCC, both in low and medium voltage.
- Panels for the conversion from direct current to alternating current for photovoltaic systems.
