From the grid to the last connection.
HT & LT lines, primary and secondary substations, transmission backbones and the electromechanical systems that energise critical infrastructure.
Spentech is a turnkey power infrastructure contractor delivering high-voltage transmission, primary and distribution substations, and full medium- and low-voltage networks for utilities, industrial clients and donor-funded rural electrification programmes across East and Southern Africa.
Our in-house teams undertake route surveys, tower spotting, foundation works, stringing of ACSR and OPGW conductors, substation civil and structural works, GIS and AIS switchgear erection, transformer installation up to 220/132/66/33 kV, protection & control panel wiring, SCADA integration, and end-to-end testing and commissioning to IEC and IEEE standards.
From a 220 kV transmission corridor to a single LT service drop, every package is delivered under a single accountable contract — engineered, energised and handed over with complete as-built documentation, protection settings and operator training.
