STRUCTURALFEATURES
1.Thecabinetof theGGDAClow-voltage Switchgearadoptsauniversalcabinet form,assembled with C-sectionsteel. Theframecomponentsand specialsupporting partsare suppliedbythecompanyto ensure the accuracyand qualityof thecabinet.Thecomponents of the universal cabinet are designed basedona modular principle,with 20-module mounting holesandahighuniversalcoeficient,alowingfactories toachievepre-production,reducing manufacturing cycles,and improving efficiency.
2.The designofthe GGDcabinet takes into account the heat disipation isues during operation.There are diferent numbersof heat disspation slotsatthe upperandlowerendsof thecabinet.Whenthe electrical components inside the cabinet generate heat,theheatrisesand is discharged through theupperslot,whilefreshaircontinuouslyenters the cabinetthrough the lower slot.This creates a natural ventilation channelin the sealed cabinet from botom to top, achieving the purpose of heat dissipation.
3.The GGDcabinetisdesigned according totherequirementsof modern industrialproductstyling,using thegolden ratio method to design the cabinet'sappearance and the division size of each part.This makes theentire cabinet aesthetically pleasing.
4.Thecabinetdoorsareconnectedwiththeframebyhinge-type movablechains,makingiteasytoinstallanddismantle. Atthe folded edgesof the doors,there isan embedded mountain-shaped rubber strip.When the dooris closed,the rubberstrip between the doorand theframe hasacertain compressionstroke,preventing directcolisionbetween the door and the cabinet and improving the protection level of the door.
5.Theinstrumentdoorwith electricalcomponents isconnectedtotheframe by multiple strandsofsoft stel wire.The installtionpartsinsidethecabinetareconnectedtotheframewithembossed washers,formingacompletegrounding protection system for the entire cabinet.
6.Thesurfaceofthecabinetistreatedwith high-pressureelectrostaticpowdercoating.Ithasstrongadhesionand good appearance.Theentirecabinethasamatetone,avoidingglareefects,creatingacomfortable visualenvironmentfor operators.
7.Theitems on thecabinet bodycan beremoved when needed to facilitate theassembly andadjustmentof the main busbaron site.Thefour corners of thecabinet top are equipped with lifting rings forlifting and shipping.
8.The protection levelof thecabinet is IP30.Users canalsochoose between IP20and IP30according to the requirements of the operating environment.
