Kufotokozera Kwachidule:

Pulagi yakutsogolo ya 8.7/15kV yaku Europe ndi ya European 630A ndi 1250A pulagi mndandanda. Ndizoyenera

kwa (chingwe chamagetsi cholumikizira) mkati ndi kunja kwa mayunitsi akuluakulu a mphete, ndipo chimalumikizidwa ndi

mkati ndi kunja mizere bushing sockets wa switchgear, zodutsa-khoma bushings wa kugawa chingwe

bokosi, ndi zitsamba ziwiri zodutsa ndi mabawuti. Imagwiranso ntchito pazida zamtundu wa bokosi. Iwo

imapereka kutsekereza kwathunthu ndi kulumikizana kosindikiza kwathunthu kuchokera ku zingwe zamagetsi kupita ku switchgear kapena kugawa chingwe

mabokosi. Pulagi yakumbuyo imalumikizidwa ndi pulagi yakutsogolo yaku Europe kapena pulagi ina yakumbuyo, ndikuwonjezera

chingwe cholumikizira lupu (nthambi) chomwe sichingalumikizidwe mwachindunji ku casing. Mchira ukhoza kulumikizidwa

molunjika ndi pulagi yotsekera, kapena imatha kukulitsidwa kulumikiza chingwe china chakumbuyo kapena chomangira pulagi chakumbuyo.

Pamene pulagi yakutsogolo ikugwira ntchito, imalumikizidwa ndi socket ya switchgear bushing ndi mabawuti; mchira wake ukhoza kukhala

mwachindunji otsekedwa ndi zipangizo insulating, kapena anawonjezera kulumikiza ndi pulagi kumbuyo mtundu cholumikizira magetsi

kapena pulagi yakumbuyo mtundu womanga mphezi. Chogulitsacho chimagwirizana ndi kapangidwe ka C-mtundu wa bushing mu miyezo EN50180

ndi 50181.
