Safe crews, tested installations, utility-grade materials.
Medium voltage leaves no room for shortcuts. Our sites run on TANESCO standards, supervised crews and tests before anything is energised.
- TANESCO technical standardsEvery line, transformer and panel is specified and built to the utility's standards.
- PPE and supervision on every siteTrained crews, supervisors and safety equipment are part of our scope and price.
- Testing before energisationEarthing, insulation and protection checks; commissioning with the client and TANESCO.
- Daily progress reportingWritten reports by activity — pits, poles, stringing — so clients see where every kilometre stands.
