FAQ
Q: Dab tsi yog qhov kev xaiv thiab kev tsim kho kev ceev faj rau BV hlau?
A:
Tsis txhob siv cov kav dej ntau dhau, uas tuaj yeem ua rau khoov nyuaj:
- BV hlau muaj siab rigidity; thaum khiav ntau lub xov hlau sab-los ntawm- sab hauv ib lub raj, nws raug nquahu kom txo tus lej lossis siv BVR xaim hloov.
Siv cov kaus mom hlau los yog cov terminals thaum txuas:
- Ib leeg -strand khoom hlau yog yooj yim kho thiab muaj kev tiv thaiv qis dua.
- Tsis txhob ncaj qha qhwv tooj liab nyob ib ncig ntawm lwm cov xov hlau rau kev sib txuas:
- Siv cov txheej txheem txuas los tiv thaiv oxidation thiab overheating.
Them mloog mus rau xim coding:
- Liab / Daj / Ntsuab: nyob hlau
- Xiav: Neutral hlau
- Daj-Green: av xaim
