Daim ntawv thov
Haum rau kev teeb tsa sab hauv tsev: feem ntau hauv cov chaw nres tsheb fais fab thiab sab nraum zoov: hauv cov kab hluav taws xob, hauv av, thiab ntawm cov tais cable rau kev lag luam, hloov-boards thiab chaw nres tsheb fais fab. Vim muaj qhov zoo thiab cov yam ntxwv ntawm cov neeg kho tshuab, cov cable no tsim nyog thaum yuav tsum muaj kev tiv thaiv kev siv tshuab lossis hauv cov ntawv thov uas yuav tsum muaj kev puas tsuaj rau txhua yam.

Cov qauv
Lub hwj chim cable yog tsim raws li IEC 60502-1: 2004.
Nws yog tsim nyog los muab tso rau hauv lub hwj chim cable kab nrog rated voltage ntawm {{0}}.6/1kv (U0/U) rau fais fab kis.
