Tooj liab hlau

Tooj liab hlau yog feem ntau siv nyob rau hauv kev tsim kho ntawm hluav taws xob faib tes hauj lwm, kis kab mob, grounding systems, xob laim pas nrig, thiab nyob rau hauv daim ntawv thov vuam.

Ib qho ntawm qhov zoo ntawm cov hlau tsis muaj tooj liab yog nws lub peev xwm nqa tam sim no, uas ua rau nws zoo tagnrho rau cov ntawv thov uas tsis tshua muaj hluav taws xob tiv thaiv thiab kev siv hluav taws xob siab. Tsis tas li ntawd, tooj liab yog cov khoom siv tiv thaiv corrosion heev, uas txhais tau hais tias liab qab tooj liab hlau tuaj yeem nyob ntev yam tsis muaj kev puas tsuaj.
