Šíma Elektro was born from the belief that energy infrastructure can be reliable, safe and uncompromising. We started as a small team of electrical engineers and gradually grew into a company delivering complex distribution-network projects for the most demanding clients.
Today we specialise in the construction and maintenance of distribution networks up to 110 kV, local distribution systems and live working. We cooperate with leading players in the energy sector — our partners include ČEZ Distribuce, developers and operators of commercial sites.
