Reconstruction of Traffic Surfaces Pavement Structure of Electrical Energy Facilities

Reconstruction of internal traffic area (road) within power transmission and distribution substation or other electrical power plant is complex and demanding investment which requires cooperation and synchronism of participants coming from various engineering background. It is carried out mostly alike as ordinary road but taking in account additional regulations due to safe operation and use of equipment in hazardous areas close to electrical installations and apparatus. Safely engineered and well-built road connecting public road and internal road of power substation has a key role in aspects of: safe and fast access of heavy machinery and trucks close to electrical equipment for normal service or during the intervention (failure, damage, fire, oil spillage), water drainage, reduction of maintenance costs. During the reconstruction of asphalt pavement surfaces on power plants, it is necessary to consider that parts of substation are supplying electricity. Before any work is started, preliminary precaution measures are set. These consist of: detecting area close to high voltage and detection of borders of safe working area (surface but also in height). Prior to reconstruction it is necessary to carry out preparatory work on parts of distribution network and power substation such as: detecting existing cables and facilities, creating an earthing mesh, laying new power cables, laying signaling and communication cables, building oil-drainage system and firm surface. When substation is switching network state or is in faulty condition – no work is allowed until normal operating condition is established which may affect the time limits of project. Throughout the reconstruction it is important to coordinate work on electrical installations and civil (construction) works and to try to achieve maximum quality. Another key issue is communication among engineers from a various discipline and trying to understand and develop best practice for future projects.
