Uwitekainsinga z'amashanyarazihamwe na polyethylene (XLPE) ihuza imirongo yo hejuru yagenewe gushyirwaho amashanyarazi hamwe numuyoboro uhinduranya amashanyarazi hamwe na voltage nominal Uo / U 0.6 / 1 kV cyangwa mumashanyarazi ataziguye hamwe na voltage ntarengwa ukurikije ubutaka 0.9 kV.
Intsinga zifasha (gutwara) zeru zikoreshwa mukubaka imiyoboro mumijyi no mumijyi kandi insinga zo kwifashisha ubwazo ni iyo kubaka imiyoboro yo gukwirakwiza muri utwo turere.
Intsinga zo kwishyiriraho hejuru zishobora gukoreshwa muburyo butandukanye bwo kwishyiriraho: kumanikwa yubusa;hagati y'imyanya;ku mpande zihamye;ibiti n'inkingi.Biremewe gufata uduce tw’amashyamba bidakenewe gutunganywa no gufata neza gufungura biremewe.
Intsinga zifasha kuyobora zeru, bundle yose irahagarikwa kandi itwarwa numuyoboro ushyigikira, bikozwe muri aluminium.
Kwiyubaka-kwiyubaka, guhagarika no gutwara bundle yose bikorwa nicyiciro cyabigenewe.
Bundles irashobora gushiramo imwe cyangwa ebyiri ziyongera kumatara rusange no kugenzura byombi.
