BENEFITS

1. Improvement of the established levels of continuity and quality in the electric power supply of the circuits involved.

2. Change of sodium luminaires by LED technology.

3. Decrease in the incidence of breakdowns, caused by the constant exposure of networks to climatic conditions and external agents, when installing suitable protection equipment.

4. Increase in operational backups of the network and improvement in the quality of the electric service.

5. Increase in the height of poles, assemblies and the construction of new networks of low and medium voltage, which allows to reduce the probability of the impact of vehicles against electrical conductors, telephony and cable.

6. Progressive solution of the problem of expiration of the electrical network.
