GE is a global market leader for disconnectors (disconnect switches) since 1960, with 8 product facilities in 7 countries and hundreds of thousands installations in more than 130 countries around the world. The portfolio includes disconnectors for AC applications (up to 1,200 kV), for DC applications (up to 1,000 kV) and for railway applications. GE also offer power connectors to connect two or more conductors for a continuous electrical path.
GE prides itself on being one of the leading manufacturers of Disconnectors (Switches) in the world. GE offers flexible and reliable layout configurations up to 1,200 kV designed and tested to support international standards such as IEEE, IEC and GB (China).
From scorching hot climates to extreme cold environments, and areas of intense seismic activity, GE solutions are field proven with installations across the globe.
GE disconnectors are available in a variety of physical forms based on substation configurations and a space requirements. Our highly experienced engineers and technicians can provide expert advice and support in defining customized solutions.
Vertical Break Disconnectors
Center Break Disconnectors
Double-Side Break Disconnectors
Pantograph and Semi-Pantograph Disconnectors
Knee Type Disconnectors
XD/GE Disconnectors
The portfolio includes:
Disconnectors (DSC) for HVDC applications are designed to specific constraints and requirements typical for DC applications, that are quite different compared to AC applications. They are requested to withstand DC voltage open gap and to ground to ensure safety for the people in the substation and to permit proper and safe layout configuration. In some cases, like for filter applications, they are requested to break a sum of harmonic currents at a certain voltage (amply smaller than the rated voltage of the disconnector) due to the ripple created by harmonics on the reactances.
All these DC disconnectors take benefit of huge experience and installed base of AC disconnector technology delivered worldwide in regards to design technology and quality e.g. supplier qualification, assembly processes or ISO conformity.
The railway network has to be globally interconnected, and the connection between systems with different voltages and frequencies (electrical borders) can only be achieved through the disconnecting points that decouple them.
Disconnectors are an essential element of the supply systems (overhead conductors or ground level wires) that feed the trains. Their function is to disconnect the cells that make up the line in order to supply energy only when a train is running.
Power connectors join two or more conductors for the purpose of providing a continuous electrical path. GE offers tap, terminal, splice and non current carrying connectors.
The GE portfolio offers an extensive range of HV power connectors for substations. Several other types of connectors not mentioned are available, or can be specifically designed.
The test results and field experience demonstrate that the GE design criteria provides the best performance for connectors applications up to and over 800 kV, both for AC and DC applications.
GE’s connectors have been supplied to many customers worldwide and thanks to our consolidated experience, after more than 40 years no corrosion nor over-heating issues have been reported.
