Gas-Insulated Substations - GIS Dielectric Gas. A gas-insulated substation (GIS) uses a superior dielectric gas, 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 SF6 gas inside grounded metal enclosures.
Medium-Voltage Switchgear Doesn't Require SF6 as ... has introduced another medium-voltage switchgear that doesn't require sulfur hexafluoride (SF6) as the insulating gas: the 8DAB 12.The system uses clean air consisting only of the natural constituents of ambient air as the insulating gas. The switchgear is a new addition to the 8DA and 8DB product family and also works with the proven vacuum switching technology.
Transformer services - Siemens Energy Global life span of a transformer largely depends on the ageing of the solid and liquid organic insulating materials. In normal operating conditions, below the maximum permissible load, and with regular maintenance and care, a transformer's lifespan can be extended to well over 30 years.
Insulation components and materials - Hitachi ABB Power Grids lifetime of a transformer depends on the reliability of the insulation used. Hitachi ABB Power Grids pays particular attention to the manufacturing systems and processes used and continues to improve product quality and reliability by investing in modern equipment and experienced people.
