Ib qho kev sib txuas ntawm lub thawv muaj ntau yam tseem ceeb: npog, lub cev, terminals, diodes, txuas xov hlau, thiab cov khoom sib txuas.
Cov kev xav tau ntawm kev siv yog raws li nram no:
1) Lub casing yuav tsum muaj zog tiv thaiv - kev laus thiab UV tsis kam;
2) Nws yuav tsum ua kom tau raws li qhov yuav tsum tau siv rau hauv qhov hnyav sab nraum zoov ib puag ncig;
3) Tus kheej - xauv muaj nuj nqi ua rau kev sib txuas yooj yim dua thiab ruaj ntseg;
4) Nws yuav tsum muaj cov qauv kev sib khi tsis zoo thiab kev tshawb fawb los tiv thaiv - hluav taws xob tiv thaiv hluav taws xob tiv thaiv kev nyab xeeb zoo dua;
5) Cov terminals yuav tsum tau ua kom ruaj khov thiab muaj kev sib tw zoo rau lub busbar;
6) Lub luag haujlwm tseem ceeb ntawm lub diode yog unidirectional conduction;
7) Kev sib txuas thiab kev sib txuas ntawm cov xov hlau: Lawv yuav tsum muaj kev ua haujlwm zoo, thiab cov txiv neej thiab poj niam plugs yuav tsum muaj tus kheej -locking muaj nuj nqi kom yooj yim dua thiab txhim khu kev qha hluav taws xob sib txuas ntawm lub hnub ci vaj huam sib luag thiab hluav taws xob.
