Switchgear XGNS1-40.5 includes a series of expandable SF6-insulated metal-clad switchgears at the voltage rating of 40.5kV. All live parts of primary high-voltage circuit are wholly enclosed in a welded cabinet of 3mm-thinckness stainless steel sheets, which gives a small volume. The switchgear is not subject to the influence of surrounding conditions so that it guarantees the safe and reliable running and zero maintenance. It can be integrated as module by using plug-in expansion busbar. Meet requirements of end users or network nodes and satisfy demands of various substations and switching stations, box-type substation, cable branch boxes and wind turbine towers. It features the compact structure, safety, reliability, long life and zero maintenance.
XGNS1 series provides transformers with following protections:
l Load switch-fuse composite apparatus.
l Vacuum circuit breaker with relay protection
l Complete functions provided by basic functional units such as load switch, load switch+fuse composite apparatus and circuit breaker.
l Small volume, light weight, size down to 500*1010*1900 (mm) and particularly suitable for wind turbine tower application.
l Simple operation, safe use, easy maintenance and zero maintenance for 30 years.
l Enclosed design, zero exposed live component and long-term availability under severe conditions.
l Flexible modular integration with plug-in expansion busbar.
l Elevation: Not more than 5000m above the sea level.
l Ambient temperature: Max.: +50℃, Min.: -40℃.
l Relative humidity: daily average is not more than 95%, monthly average is not more that 90%.
l No apparent pollution of corrosive or combustible gas around.
l No regular violent vibration.
l Note: if deviation for normal service conditions occurs, the customer should inform the manufacturer before production.
