Tlhaloso ea Sehlahisoa
GGD AC low-voltage switchgear e loketse litsamaiso tsa kabo ea matla tse nang le AC 50Hz, matla a sebetsang a lekantsoeng a 380V, 'me a lekantsoe ho sebetsa hona joale ho fihla ho 3150A ho lifeme tsa motlakase, li-substations, lifeme le likhoebo tsa merafo, ka sepheo sa ho fetolela matla, ho ajoa, le taolo ea matla, mabone le thepa ea ho aba.
GGD AC low-voltage switchgear ke mofuta o mocha oa AC low-voltage switchgear e entsoeng ho latela litlhoko tsa baokameli ba Lefapha la Matla, basebelisi ba matla a maholo le mafapha a meralo, ho latela melao-motheo ea polokeho, moruo, kahlolo e molemo le ho tšepahala.Sehlahisoa se na le bokhoni bo phahameng ba ho pshatla, botsitso bo matla le bo futhumatsang, merero ea motlakase e feto-fetohang, motsoako o bonolo, ts'ebetso e matla, sebopeho sa novel, le boemo ba ts'ireletso, 'me e ka sebelisoa e le sehlahisoa se ntlafalitsoeng bakeng sa li-switchgear tse tlase-voltage.
GGD AC low-voltage switchgear e boetse e kopana le litekanyetso tse kang IEC439 "Complete Low-voltage Switchgear and Controlgear" le GB7251 "Low-voltage Complete Switchgear."
Maemo a tshebediso
Mocheso oa moea o potolohileng ha oa lokela ho feta +40 ℃ mme o se ke oa ba tlase ho -5 ℃, 'me mocheso o tloaelehileng nakong ea lihora tse 24 ha oa lokela ho feta +35 ℃;
Ho khothaletsoa ho kenya ka tlung, 'me bophahamo ba sebaka sa ts'ebeliso ha boa lokela ho feta 2000m, e lokelang ho boleloa ha o laela;

Hlahisa Setšoantšo sa Dimensional
mehato ea ho fana ka taelo:
Ha o etsa odara, mosebelisi o lokela ho fana ka:
- Setšoantšo se ka sehloohong sa kabo ea potoloho le setšoantšo sa sebopeho, matla a ho sebetsa a lekantsoeng, e lekantsoeng ea hona joale ea ho sebetsa, lisebelisoa tsa ts'ireletso tsa hajoale, le litekanyetso tse hlokahalang tsa tekheniki.
- Bontša litlhaloso tsa thapo e kenang le e tsoang.
- Mohlala, litlhaloso, le bongata ba likarolo tsa mantlha tsa motlakase ka har'a khabinete ea switch.
- Haeba ho hlokahala marokho a libese kapa libaka tsa libese pakeng tsa likhabinete tsa switch kapa likhabinete tse kenang, litlhoko tse khethehileng tse kang bolelele le bolelele ho tloha fatše li lokela ho bontšoa.
- Ha li-switches likhabinete li sebelisoa maemong a khethehileng a tikoloho, litaelo tse qaqileng li lokela ho fanoa ha o laela.
- 'Mala oa bokaholimo ba khabinete ea switch le litlhoko tse ling tse ikhethang.
