1. Lub thav duab ntawm substation yog ua los ntawm hlau thiab lub kaum sab xis hlau galvanized kom muaj lub zog txaus.
2. Cov ntawv hlau uas dov txias, cov hlau tsis xeb, cov ntawv txhuas lossis cov ntawv sib xyaw ua ke muaj yeeb yuj yogsiv rau lub qhov rooj kaw.
3. Txhua lub cubicle raug sib cais los ntawm cov hlau ntawv kom sib txawv sab hauv.
4. Cov khoom siv teeb pom kev zoo tau teeb tsa hauv LV & H.V. cubicles thiab transformer cubicle rau kev saib xyuas thiab kev txij nkawm.
5. Lub hau yog ob txheej kom tiv thaiv qhov kub ntawm qhov kub nce ntxiv.
6. Siv cua ntuj los ua kom lub transformer ua haujlwm tau zoo. Thaum qhov kub hauv lub transformer cubicle siab dua qhov kub uas tau teem tseg, lub kiv cua uas ntsia rau saum toj yuav pib ua haujlwm thiab tswj tau.qhov kub thiab txias.
7. Cov khoom siv kaw tau muab tso rau ntawm qhov tig kom tsis txhob muaj dej noo.
8. Kev tiv thaiv zoo meej thiab kev ua haujlwm yooj yim, tshwj xeeb tshaj yog "tsib-pov thawj" kev ua haujlwm ntawm HV sab ua kom muaj kev ruaj ntseg ntawm kev saib xyuas.
9. Cov khoom zoo nkauj thiab ntuj tsim nyob rau hauv qee qhov chaw ib puag ncig.
① Qhov siab: <1000m
② Qhov kub thiab txias: -25 ℃ -+ 40 ℃
③ Cua ceev: <30m/s
④ Cov av noo sib piv: <90%
