Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, insulating gas, 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 gaz sf6 can do in centimeters.Get price

Construction firms realize the benefits of an integrated BIM

Spatial Technology Key to Digitalizing The Construction IndustryBim+Geospatial Interoperability Standards Improves Construction WorkflowsAec+Geospatial Interoperability Standards Encourages Open Source SolutionsConclusionThe McKinsey Global Institute estimates that the world will need to spend $57 trillion on infrastructure through 2030 to keep up with global GDP growth. This is a massive incentive for the construction industry to transform productivity and project delivery through new technologies and improved practices. McKinsey reports that large construction projects typically take 20 percent longer to finish than scheduled and are up to 80 percent over budget. McKinsey & Company suggests that the construction industry is ripe for disruption and two of the technologiesthat it believes will be key in that anticipated transformation are geospatial and BIM. The UK Government as part of its buildinginformation modeling (BIM) initiative has saidrepeatedlythat it expects the big payoff of a digital model will be duringoperations and maintenance, which typically represents 80% of the cost of afacility. Companies who take on design, build, and maintain and/or operateprojects have found significant benef...Get price
