Zw7-40.5 letoto la ka ntle la motlakase o phahameng oa motlakase oa motlakase ke mekhahlelo e meraro ea AC 50Hz. Li-switchgear tse tsoang kantle tse nang le matla a phahameng a matla a 40.5Kv. E na le mochini oa ts'ebetso ea selemo kapa mochini o sebetsang oa motlakase, e khona ho laola karohano le ho koala motlakase, hape e ka boloka matla a bolokiloeng ka letsoho, ho arola le ho koala ka letsoho. Ts'ebetso ea moralo e fihlela litlhoko tsa GB1984 "AC high voltage circuit breaker" standard ea naha, 'me e kopana le litlhoko tsa IEC62271:100 "High voltage AC circuit breaker" standard ea International Electrotechnical Commission. ZW7-40.5 vacuum circuit breaker e sebelisoa haholo-holo bakeng sa taolo le ts'ireletso ea tsamaiso ea ka ntle ea 35KV ea phetisetso ea matla le phetoho, hape e loketse ts'ebetso e tloaelehileng le tšireletso ea potoloho e khutšoanyane ea marang-rang a kabo ea matla a litoropo le mahaeng le likhoebo tsa indasteri le tsa merafo. Sebopeho se akaretsang sa sehlahisoa ke mofuta oa litšiea tsa porcelain; Botlolo ea porcelain e kaholimo e na le kamore ea ho tima ea arc ea vacuum, 'me botlolo ea porcelain e tlase ke botlolo ea litšiea tsa porcelain. E loketse ts'ebetso ea khafetsa. E na le litšoaneleho tsa ho tiisa hantle, ho thibela botsofali, ho hanyetsa khatello e phahameng, ho se chese, ha ho na ho phatloha, bophelo bo bolelele ba tšebeletso, ho kenya habonolo le tlhokomelo.
