Design Activities’ Orientation

Egem

  • EHV/HV and HV/HV substations and transformer stations of power transmission system
  • EHV/HV and HV/LV distribution and transformer substations
  • Substations for power generation (power plants)
  • Substations for heat generation (heating plants)
  • Industrial power distribution
  • Outdoor high voltage and extra-high voltage overhead lines

Substations

Main Activities

  • Technological parts - complete engineering of substations power sections, power stations, heating stations and industrial plants
  • Control systems - complete engineering of control systems, protections, measurement and communication for substations, power stations, heating stations and industrial plants
  • Construction parts - complete engineering of civil parts or civil part modification

Method of Implementation

  • General design
  • Author project inspection
  • Feasibility study
  • Review of civil part, documentation necessary for permission procedure
  • Civil documentation for the building permits procedure
  • Execution of the design documentation in full scope including 3D design
  • Renewal and verification of As-built documentation
  • Documentation necessary for selection of the contractor
  • Detail design
  • As-built documentation
  • Operational documentation
  • Consultancy

Overhead lines

Main Activities

  • Technological part - complete design preparation
  • Civil construction part - geodetic measurement (convencional, LIDAR system, photogrammetry), geological survey, design and foundation calculations
  • Complete engineering activities - project planning, route selection, final negotiation

Method of Implementation

Egem

  • Proposals for alternative solutions, technical and economical comparison of alternatives
  • Towers configuration proposal, static calculations of the structures and static calculations of towers for additional installation of antenna systems
  • Preparation of construction documentation and workshop documentation
  • Check of as-built state of existing structures and repair proposal
  • Calculations of line rating, electric and magnetic field, dangerous induction, capacitive and galvanic effects within the communication line
  • Design documentation necessary for the planning and civil construction permission procedure, operational documentation, contractor detail design
  • Preparation of operational documentation based on the current status and customer's requirements
  • EHV lines Optical routes (OPGW, ADSS, GWWOP)
  • Preparation of technical requirements and data for tenders

For all the above mentioned activities, we dispose with appropriate SW such as ACAD, NEXIS, and PLC-CAD.

We take an active part in the development of technical standards and the part in CIGRE international organization.
