Insinga zifatanye ni ngufi ya polyethylene ifatanye (XL-PE) ikoreshwa mu gufunga. Insinga zifatanye zikwiriye imiyoboro yo kohereza no gukwirakwiza ibikoresho hamwe n’amashanyarazi afite voltage ya ac frequency kugeza kuri 500KV. Kuri ubu, insinga nyinshi zikoreshwa mu gufunga zikoreshwa na polyethylene ifatanye.
Insinga zifatanye ubusanzwe ziva ku nsinga zifite ubushyuhe bukozwe mu bikoresho bifatanye. Igikoresho gikoreshwa cyane ni polyethylene ifatanye (XLPE). Uburyo bwo guhuza ni ugukora imiterere ya molekile ya polyethylene (PE) binyuze mu buryo bwihariye bwo kuyitunganya kugira ngo habeho imiterere y'umurongo wa polyethylene ufatanye. Kubera iyo mpamvu, ubushyuhe bwemewe bwo gukora mu gihe kirekire buzamurwa kuva kuri 70℃ kugeza kuri 90℃ (cyangwa hejuru), naho ubushyuhe bwemewe bwo mu gihe gito buzamurwa kuva kuri 140℃ kugeza kuri 250℃ (cyangwa hejuru), ibi bikaba birushaho kunoza imikorere nyayo mu rwego rwo gukomeza imikorere myiza y'amashanyarazi.
Hari ibyiza byinshi bya XLPE. Wenchang itanga ubwoko bwinshi bwa XLPE uhisemo.
Nka UL3265, UL3266, UL3167, UL3173, UL3182, UL3194, UL3195, UL3196, UL3199, UL3236 n'ibindi.
(1) Imiterere myiza cyane ya mekanike n'iy'umubiri, kurwanya imihindagurikire y'ikirere, kurwanya kwangirika neza, kurusha PVC na PE bishobora kwihanganira imihindagurikire ikomeye ya mekanike.
(2) Irwanya imiti itandukanye ya shimi, ihamye mu buryo butandukanye bwo kwangiza ibintu hirya no hino.
(3) Umurambararo w'inyuma w'insinga zishyushye za polyolefin zifatanye ni muto ugereranije n'insinga zishyushye za polyvinyl chloride zose zifite igice kimwe cy'ibipimo, bishobora kugabanya umurambararo w'umuyoboro ukoreshwa mu kubaka imiyoboro, cyangwa kwambara insinga nyinshi munsi y'imiterere imwe y'umurambararo w'umuyoboro, bityo bikagabanya ikiguzi cyo gushyiraho inyubako.
(4) Insinga za polyolefine zishyushye zikozwe mu mirasire y'imirasire y'amashanyarazi zoroshye cyane kurusha insinga za PVC zishyushye, ibyo bikaba byoroshye kuyishyiraho no kuyitwara, bigabanya imbaraga z'abakozi n'ikiguzi cyo kuyitwara.
(5) Ubushyuhe ntarengwa bw'insinga zishyushye zifatanye n'imirasire bushobora kugera kuri 125°C mu gihe kirekire, kandi ubushobozi bwo kuzitwara buruta ubw'insinga zishyushye za PVC.
(6) Ntirekura imyuka yangiza cyangwa imyuka y'uburozi mu gihe cyo gutwika, kandi ntabwo izangiza ibindi. Ni ubwoko bushya bw'ibicuruzwa birinda ibidukikije bijyanye n'ibisabwa mu buryo bugezweho mu bijyanye no kwirinda inkongi z'umuriro.
(7) Imikorere myiza y'amashanyarazi, ubushobozi bwo gukingira insinga buri hejuru cyane ugereranyije n'insinga za PVC, kandi igihombo kiri hagati Inguni ni nto cyane, mu by'ukuri ntihinduka iyo ubushyuhe buhindutse.
