Métodos alternativos para escavação e lançamento de cabos em usinas fotovoltaicas

Resumen

Sustainable energies generation, in which the photovoltaic energy generation is included, has been growing expressively. This fact causes the number of construction companies that work in this area to increase, intensifying competition and forcing companies to find out solutions to get advantages over others. One area where advantages could be exploited is trench execution and cable plowing, since it is one of the longest phases in the construction of photovoltaic power plants. The goal of this study is to identify alternative methods for trench excavation and cable plowing in photovoltaic power plants in Brazil. An exploratory qualitative research was conducted. Data on executive methods were collected in the literature and in interviews. Two alternative methods were identified as advantageous over the conventional method. For example, the use of plowing method’s mechanized operations could lead to shorter schedules. It also requires less workers in the field, reducing risks of injuries. In addition, plowing method requires less elements in the trench.  Hence, companies could consider their use to improve productivity in the field, making themselves more competitive.
