Project Description

1. Maintenance and repair of transmission and distribution lines and cables in Isfahan, Chaharmahal and Bakhtiari and Yazd provinces, as well as high pressure substations in the steel industry – Saba steel – Zobahan – Haft Tir and …..

2. Execution of overhead transmission lines up to 400 kV voltage level, including: foundation, installation of mast and wiring
3. Execution of cable lines up to the voltage level of 63 kV, including: cabling, cable head and joint installation with the necessary tests

4. Carrying out ascending visits to transmission and over-distribution line towers in the electrical mode to identify the defects of the lines and eliminate them
5. Execution of OPGW overhead cabling on transmission lines in cold (with blackout) and hot (without blackout)
6. Replacement of old conductors with Acss, GZACSR Gap Type up to 230 kV voltage level of new generation high capacity conductors
7. Installation of insulator and spacer between fuzzy silicon rubber up to 400 kV voltage level
8. Design, installation, implementation and testing stations’ earthing networks and high pressure line towers
9. Troubleshooting and testing all types of high voltage cables
10. Optimization of lines including: galvanizing painting of masts, modification of foundations, service and washing of contaminated insulators and installation of anti-bird bar
11. Computer simulation with software, for accurate evaluation of the stations’ ground network
12. Measurement of ohmic resistance and wave impedance of masts with modern devices to determine the efficiency of earth network and ground system

13. Measuring the resistance of the ground network of stations

14. Conducting continuity tests and step and contact voltages of the ground network of stations

15. Implementing electrical insulation with 20 kV and LV busbars
