Ukongeza ekonakalisa ubuhle bendalo, imigca yombane ephezulu egqitywe ngamawaka eevolthi iya kuba neziphumo eziyingozi kubantu abakufutshane ngenxa yentsimi ye-electromagnetic eveliswa ngeenxa zonke kubo. Oku ikakhulu kuxhomekeke kumandla ombane wombane.
Xa abantu bechanabeke kumandla ombane angama-50 ~ 200 kV/m, kusenokubakho intloko ebuhlungu, isiyezi, ukudinwa, ukungalali kakuhle, ukuphelelwa ngumdla wokutya, igazi, inkqubo ye-cardiovascular system kunye ne-central nervous system engaqhelekanga. Ngokuqinisekileyo, apha kubhekiselwa kumbane ongaphezulu kwe-100 kV imigca yokuhambisa i-ultra-high-voltage transmission, ngokwemigaqo ngokuqhelekileyo kungekhona ngeendawo zokuhlala, ngoko ke abantu abaqhelekileyo banokukhuselwa kwingozi. Kwizixeko kunye neendawo zokuhlala, ininzi yemigca yokusabalalisa amandla kunye ne-voltage engaphantsi kwe-volts eyi-1000 imiselwe kwindawo ephakamileyo, enempembelelo encinci kumzimba womntu. Ukuba umgca wothumelo lwe-voltage ephezulu phakathi kwe-1 kunye ne-100 kV kufuneka udlule kwiindawo zokuhlala, kufuneka usekwe ubuncinane kwi-6.5 yeemitha ukusuka emhlabeni.
Ukongeza, ukuhanjiswa okude kwiindawo ezininzi zelizwe lethu ubukhulu becala yi-220 kV.
I-220 kV Yuanshan North Line yindawo ebalulekileyo yokubonelela ngombane kummandla osentshona weChengdu. Kwimozulu yamva nje eqhubekayo yobushushu obuphezulu, umgca wabonakala ubushushu obungaqhelekanga kwisiphako sikaxakeka, kodwa ngenxa yokuba umgca wawunomthwalo onzima kakhulu kwaye wawungenako ukuphazamiseka, i-Chengdu Power Supply yagqiba ngoko nangoko ukusebenzisa indlela yokusebenza ekwi-equipotential kunye nomngcipheko omkhulu wokhuseleko kunye nowona mngcipheko uphezulu. ubunzima bobugcisa kwiprojekthi yokusebenza ephilayo ukuphelisa ilahleko.
Ngentsimbi yesi-7:30 kusasa, kwaqalisa ukupheliswa kokusetyenziswa kombane. Ngaphantsi kwelanga elitshisayo, abaqhubi be-8 basebenzisana ngokusondeleyo nangocwangco. Babeka ibhloko, badibanisa ileli egqunyiweyo, banxiba iimpahla zokusebenza ezikhuselekileyo, bakhwela ileli, babamba intambo ye-220 kV high-voltage kwi-equipotential, baza bapolisha ibamba locingo... Kwiiyure ezine emva koko, iqondo lobushushu lecable clamp izixhobo ezikwicala elikhulu lenqaba ye-10 zibuyele kwisiqhelo, kwaye umsebenzi wokuphelisa wagqitywa ngokukhawuleza ngaphandle kokuchaphazela ukunikezelwa kwamandla. I-220 kV Yuanshan North Line iyaqhubeka nokuthutha umthwalo "kwimeko epheleleyo", iphucula ngakumbi amandla esiqinisekiso se-kurtosis ye-Chengdu yegridi yamandla ehlobo.
