The main issue related to the protection and continuity of electric power supply in accordance with art. 181.1."Warunków technicznych jakim powinny odpowiadać budynki i ich usytuowanie" is the design and implementation of electrical network using two separate power sources which activate independently and which are applicable with the regional regulations and technical knowledge in overall. In addition, the power supply network of IT systems require proper equipment selection so the power supply can guarantee continuous and secure operation. Because of that the power distribution system implementation require high coordination with a structured cabling network installation. Due to the high quality of our installations (with consideration of the rules mentioned above) and thanks to the trust of our clients we often implement both power distribution network and structured cabling system all together. It is very important at the same time to preserve main safety regulations, e.g. those of construction or fire hazard. Also the rationalization of the energy consumption is necessary in every project.
