ETS-Project develops project and detail engineering documentation for cable and overhead power lines within the range of 35 — 750 kV. We can also design fiber-optic communication lines along overhead lines.
The set of the tasks the company can successfully solve is listed below:
- Designing 10-750 kV overhead power lines;
- Arrangement of supports according to a construction plan;
- Calculation of supports and foundations;
- Mechanical calculation of wires and ropes;
- Calculation of fittings and insulators;
- Calculation of grounding devices for HV supports;
- Calculation of transition points in engineering communications;
- Development of various types of foundations for various types of soils;
- Development of designs of insulator sets and cable fastenings;
- Calculation of wire and cable sags;
- Calculation of areas to be cleared from vegetation (trees, bushes, etc.) before installing overhead transmission line supports;
- Designing large 110 — 500 kV overhead power lines over water sources with lengths exceeding 1000 m;
- Calculation of supports and foundations;
- Mechanical calculation of wires and cables for transition points;
- Calculation of fittings and insulators;
- Development of warning lights for supports of long overhead line crossings;
Designing 10-330 kV cable lines:
- Calculation of transmission capacity for 10-330 kV cable lines;
- Development of various methods of laying cable lines (in the ground, on the overpass, by deep directional drilling, laying cables in llectors and cable tunnels/collectors);
- Calculation of stresses in cable lines;
- Development of constructions for laying cable lines;
- Development of points where cable lines meet air lines;
- Designing fiber-optic communication lines;
- Suspension of fiber optic communication line on overhead line towers;
- Calculation of thermal resistance of optical cable in overhead ground wire;
- Calculation of tensions on the surface of self-carrying optical cable;
- Calculation of supports for fiber optic lines suspension;
- Calculation of sags which might appear along fiber-optic communication lines;
- Obtaining approval from supervisory bodies.
Experience in designing power transmission lines:
- 500 kV Zagorskaya storage power station — Yartsevo overhead power transmission line with reconstruction of 500 kV Yartsevo substation;
