ABB South Africa has delivered its largest 132 kV high voltage gas insulated switchgear (GIS) board as part of a multi-million rand order to City Power’s new Sebenza intake substation.
The 132 kV GIS board comprising 38 bays is the largest such high voltage board ABB has supplied in Africa. GIS is a compact metal encapsulated switchgear consisting of high-voltage components such as circuit-breakers and disconnectors, which can be safely operated in confined spaces. GIS is used where space is limited, for example, extensions, in city buildings, on roofs, on offshore platforms, industrial plants and hydro power plants.
“ABB is a leading innovator in GIS technology especially in the areas of ratings, operations, switching technology, smart control and supervision, and compactness,” says Confidence Mabulwana, product group manager high voltage products, ABB South Africa. “As a result, ABB’s GIS offers outstanding reliability, operational safety and environmental compatibility.”
The order for the ABB HV switchgear was placed at the end of 2014 and the products were delivered in November 2015. The installation and commissioning started at the beginning of March 2016 and commissioning is planned for completion at the end of September.
The 132 kV GIS equipment was manufactured in Germany while the 132 kV to 400 kV AIS circuit breakers and surge arresters were manufactured in Sweden. ABB is responsible for supervision of all installation and commissioning. South African based company Switec is responsible for all installations of 132 kV GIS under the supervision of ABB.
