HT Electrical Work
We deliver complete High Tension (HT) engineering, design, and execution solutions for11 kV22 kV33 kVelectrical networks, encompassing both overhead transmission lines and underground HT cabling systems. Our services support transmission lines, substations, and distribution networks for utility providers, industrial establishments, and renewable energy installations.
Our technical capabilities extend to advanced power system analysis and engineering calculations, including load flow studies, short-circuit and fault level analysis, overhead line sag and tension evaluation, underground cable current rating and derating analysis, insulation coordination, earthing system design, and protection scheme planning.
