Substations tsim hluav taws xob electromagnetic, tseem hu ua hluav taws xob smog. Raws li cov kev cai tiv thaiv hluav taws xob muaj feem xyuam, rau 110 kV substation kis tau tus mob overhead kab, nws qhov chaw tiv thaiv yog 10 meters sab nraum kab, nyob rau hauv lwm yam lus, ntev npaum li cas. deb los ntawm cov kab hluav taws xob 10 meters deb ntawm qhov chaw, hluav taws xob hluav taws xob hluav taws xob muaj kev nyab xeeb yog lav.

Rau 220 kv thiab 500 kV kis tau tus mob thiab transformation system kab, qhov chaw tiv thaiv yog 15 meters thiab 20 meters feem. Raws li kev nyab xeeb ntawm sab nraum zoov lub thawv substation, qhov kev nyab xeeb ntawm 6KV yog 0.7m, 0.4kV yog qhov qis-voltage sab, thiab nws yog qhov tsis zoo rau kov. Qhov kev ncua deb hu ua kev nyab xeeb yog qhov tsawg kawg nkaus nrug ntawm tib neeg lub cev thiab lub cev them nyiaj.
