Zoo- haum rau qis- daim ntawv thov kev tswj hwm tam sim no thiab ib puag ncig uas tsis muaj zog sib nqus cuam tshuam tuaj yeem tshwm sim.
Insulated thiab sheathed cable yog tsim los ua kom ntseeg tau kev ua haujlwm hauv hluav taws xob tswj cov tshuab. Nws nta PVC ua ob qho khoom siv rwb thaiv tsev rau cov neeg siv khoom thiab cov ntaub qhwv sab nrauv, muab kev tiv thaiv zoo tiv thaiv ya raws, cuam tshuam rau lub cev, thiab tshuaj lom neeg corrosion. Cov neeg siv feem ntau muaj xws li qis-voltage fais fab faib network thiab daim ntawv thov teeb liab / tswj Circuit Court.
