Qhov zoo: Muab qhov zoo sib npaug ntawm cov nqi-zoo thiab hluav taws xob conductivity. Nws yog qhov sib dua ntawm qhov hnyav piv rau tooj liab, uas tuaj yeem ua tau zoo hauv qee yam kev siv.

Disadvantages: Prone rau corrosion thiab muaj qis conductivity tshaj tooj liab. Nws kuj tseem yuav xav tau kev tiv thaiv ntxiv los tiv thaiv oxidation.

Daim Ntawv Thov Field: Siv rau hauv cov kab xa hluav taws xob, transformers, thiab lub cev muaj zog windings qhov hnyav thiab tus nqi yog xav txog.
