China Aluminum Casting and Aluminum alloy Forging Manufacturer, Leading Precision Machinery Parts Supplier, High Quality, Competitive Price, Leading Manufacturer. ISO9001 Quality. Fast Delivery.
GIS switchgear tank cover is the key components for gas-insulated switchgear, Tanks also names enclosures,housings,material and processing technical usually adopted Aluminum precision casting,such as Low pressure die casting, high pressure die casting,gravity casting,Sand casting. which casting method depend on your products design.
our factory is GIS/AIS/HV Transformer/Cable Terminations casting aluminium parts supplier, products including End Fittings(Flanges/Enclosures/Conductors) and so on.
reliable and consistent products with high quality, and strict during-production and after-production inspection such as anti-leaking test, spectrum, X-rays and so on,surface treatment have anodizing, paint spraying,sand blasting, we have been gained good credit from all the clients.
For any aluminium casting products (varieties of housing, shell and cover products), we are confident we can offer you good quality and excellent service, welcome any inquiry and request from all over the world.
Steel material be adopted in GIS enclosures/housings:
There are two basic tasks of the enclosure: to keep the gas pressure inside and to be gas tight so that SF6 will not be released to the atmosphere. Both tasks can be well covered by using sheet steel materials. Cast steel has porosities that cannot guarantee such high gas tightness values as required for GIS.
Steel is relative easy to weld and to form. Therefore, the steel enclosures have been welded by steel sheets that have been mechanically formed to cylinders and then were welded.
Aluminum material be adopted in GIS tanks:
Used for the conductors as an extruded pipe or in cast technology. For enclosures aluminum is used in cast technology or with welded sheet materials using longitudinal welds or spiral welding processes.
Extruded pipes can be used as conductors in a straight bus bar section. When conductors are used inside disconnecting or ground switches, the required shape and design requires a casting technology.
The disadvantage of cast aluminum in the early years was that the insulation gas was released to the atmosphere due to its porosity.
Today, most enclosures are manufactured in cast aluminum as the top performer for GIS In pic shown Straight conductor graphic that manufacture by aluminium.
aluminum alloy casting parts with machinery processing,surface treatment such as coating painting or anodizing, each Fittings must pass several inspection before shipment, such as water pressure test (industrial inspection) operation.
GIS parts including convert plate/GIS housing/ tank/ pressure vessel/electric conductor/conversion board, passed CNLA laboratory test strain tensor analysis and bursting pressure test, construct a more complete production line, and accept the orders and produce products.
GIS Tank aluminum alloy castings parts and accessories for the transmission and distribution of energy equipments, such as ABB HUBBELL TE SIEYUAN is our good customers.
GIS, Gas Insulated Switchgear uses SF6 inert gas as the insulation. Its main purpose is to be a switch at a transformer station, and presently, it is applied to the engineering of transmission and distribution of energy extensively.
