Iliceto Shield Wire Scheme: an application to HV Line in Tanzania

Iliceto Shield Wire Scheme (ISWS) is a rural electrification scheme that uses the shield wires of High Voltage (HV) lines as conductors and an earth return to provide power at Medium Voltage (MV) to remote locations at a lower cost than the traditional methods. The present paper includes the main results of an application of this method to a HV line in Tanzania, Chalinze-Hale-Tanga. The application is finalized to find out its technical feasibility. The results show that rural electrification of villages near the Chalinze-Hale-Tanga with the ISWS is technically feasible. It allows also significant economical savings compared to the traditional scheme, mainly because no new tower or pylon need to be erected except for MV spur lines from the HV line to the single village.
