1. Kusarudzwa kwemaitiro makuru: mavharivha evhavha anofanirwa kusarudzwa maererano nemaitiro eunyanzvi akanyorwa mune zvinodiwa.
2. Paunenge uchishandisa chivhariso chevharuvhu yekudzivirira mheni overvoltage, mukuwedzera kune mota dzinotenderera, sarudza zvinosunga zvine akasiyana ekushandisa voltage renji uye akasiyana system software grounding nzira.
3. Iyo yakasara yekushanda kwekushanda kwevhavhavhavhavha yekuvhara pasi pechigadziro chekugadzirisa uye kubuda ikozvino haigoni kudarika 71% yemheni inoputika yakazara-wave inomira kushanda kwemhepo (BIL) yezvigadzirwa zvemagetsi pasi pekugadzirisa (kunze kwemagetsi anotenderera).
4. Iyo yakayerwa ikozvino yesimbi oxide inosunga uye kabhoni-kabhoni composite mavharuvhu zvinosunga zvinofanirwa kuzadzisa zvinotevera zvinodiwa:
(1) 110kV inonzwisisika yekudzivirira yepasi isiri pasi pe0.8Um.
(2) 3 ~ 10kV uye 35kV, 66kV system software haisi pasi pe1.1Um uye UM;3kV uye pamusoro jenareta set system software yakanyanya kushanda voltage haisi pasi pe1.1 nguva.
(3) Iyo yakayerwa ikozvino yeasina kwaakarerekera point arrester haisi pasi pe0.**Um uye 0.58Um zvakateerana;iyo yakanyanya kushanda voltage ye3 ~ 20kV generator set haisi pasi pe0.* * nguva.
5. Paunosarudza non-void metal oxide arresters semheni overvoltage kudzivirira midziyo, mitemo inoenderana inofanira kusangana.
6. Kune 110kV uye 220kV transformers avo vasina kwavakarerekera pfungwa inorondedzerwa se insulating layer, kana yekuzvitsaura switch ine urombo synchronous performance inoshandiswa, iyo metal oxide arrester inofanira kuchengetedza isina kwayakarerekera point ye transformer.
7. Void-free metal oxide arresters inorongwa maererano neyakajairwa yavo yekuchaja uye kubuda kwemhepo.
8. Mubatisi ane system software yakatarwa ikozvino ye35kV uye pamusoro anofanira kunge akashongedzerwa nekuchaja uye kuburitsa posture monitoring software.
