Geographic Information Systems (GIS) in Zimbabwe

Dr Gary Hunter from Australia recently spent three months in Zimbabwe assisting medium-sized local authorities to implement Geographic information Systems (GIS). Following his successful six-month deployment with the City of Bulawayo in 2014 on behalf of Australian Aid and GIZ, in 2015 he was supported by GIZ to return to Zimbabwe to work with the local authorities in the towns of Gweru, Kadoma, Chinhoyi and Kariba.Get price

Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, gaz sf6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in sf 6 gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what sf 6 can do in centimeters.Get price
