Insinga zirinda ubushyuhe mu by'amabuye y'agaciro (MI Cable) ni insinga ikora neza kandi idashya ishingiye ku buryo bw'ibikoresho by'insinga zidakora neza. Bitandukanye n'insinga zisanzwe zikoresha ibikoresho byo gukingira ubushyuhe mu by'ubushyuhe nka PVC,XLPE, naLSZH, Insinga ya MI ikorwa hakoreshejwe icyuma gifata umuringa, icyuma gifata umuringa kidakora neza, hamwe n'ibikoresho bikingira magnesium oxide (MgO) nk'imiterere y'ibanze yayo. Iyi sisitemu y'ibikoresho igena imikorere yayo ihamye mu gihe cy'ubushyuhe bwinshi n'umuriro.
Ukurikije iterambere ry’ibikoresho by’insinga, sisitemu z’ibikoresho bidafite umwimerere zikuraho neza ibibazo byo kubora, gushonga, no gusohora umwotsi w’uburozi biba mu bikoresho by’umwimerere mu gihe cy’ubushyuhe bwinshi. Ibi bituma insinga za MI ziba igisubizo cy’ingenzi ku nsinga zirinda umuriro, insinga zikoresha ubushyuhe bwinshi, n’ibikoresho by’insinga z’amashanyarazi.
Imiterere n'imiterere y'ibikoresho
Imikorere y'insinga za MI iterwa ahanini n'uburyo bw'ibanze bw'ibikoresho byayo by'insinga. Insinga zikozwe muri conductor y'umuringa ifite ubuziranenge bwinshi, itanga amashanyarazi meza cyane kandi idahindagurika cyane, bigatuma iba igice cy'ingenzi cy'ibikoresho by'insinga z'amashanyarazi.
Urusobe rw'ibikoresho byo gukingira rukoresha okiside ya manyeziyumu (MgO), ibikoresho bisanzwe byo gukingira insinga z’amashanyarazi bifite ubushyuhe burenze 2800°C. Bikomeza imikorere ya dielectric idahindagurika ndetse no mu bushyuhe bukabije, bikaba ari byo bikoresho by'ingenzi bifasha mu kurwanya inkongi.
Urukuta rw'inyuma rugizwe n'icyuma cy'umuringa gikozwe mu buryo butagira umugozi, gitanga uburinzi bwa mekanike no kurwanya ingese. Gitanga kandi ubushobozi bwiza bwo gutwara ubushyuhe no kurinda ingufu za elegitoroniki (EMI shielding). Byongeye kandi, icyuma cy'umuringa gishobora gukora nk'icyuma gitera ubutaka, byoroshya imiterere ya sisitemu no kunoza imikorere.
Imikorere y'umuriro n'ibyiza by'ibikoresho
Mu gihe cy'inkongi y'umuriro, itandukaniro mu buryo bw'ibikoresho riba rikomeye. Ibikoresho gakondo bya polymeric insinga bikunze gutangira kubora cyangwa kwangirika mu bushyuhe buri hagati ya 300°C na 500°C, bigasohora umwotsi n'imyuka mibi.
Mu buryo bunyuranye, insinga ya MI ishingiye kuri sisitemu yo gukingira umuriro idakoresha umwimerere, kandi ishobora kugumana ubuziranenge bw'amashanyarazi mu gihe cy'umuriro ku bushyuhe bugera kuri 950°C. Ishobora gukora iminota irenga 90, yujuje amabwiriza mpuzamahanga yo kwirinda inkongi nka BS 6387 na IEC 60331.
Hagati aho, insinga zayo zidashya ntizishya, ntizisohora umwotsi, kandi ntizisohora imyuka ihumanya, bigatuma insinga za MI ziba igisubizo gisanzwe cy’insinga zirinda inkongi zikoreshwa cyane mu gutanga amashanyarazi no kurinda inkongi.
Ibyiza n'imbogamizi bishingiye ku bikoresho
Ukurikije ibikoresho by'insinga, insinga ya MI itanga ubushobozi bwo kwirinda inkongi, ubushobozi bwo gutwara umuriro mwinshi, kandi ikaba imara igihe kirekire (ubusanzwe ni imyaka 40-60). Ikwiriye ahantu hari ubushyuhe bwinshi, ubushuhe, kandi hateje akaga.
Ariko, bitewe n’uko ibikoresho by’umuringa n’ibikoresho byo gukingira magnesium oxide (MgO insulation) bikoreshwa cyane, igiciro rusange cy’ibikoresho kiri hejuru ugereranyije n’iby’imiyoboro isanzwe. Byongeye kandi, imiterere y’imiyoboro yose idakora neza ituma habaho gukomera cyane, ibyo bikaba bishyiraho ibisabwa bikomeye mu gushyiraho insinga, gukora neza no kuzifunga.
Imiterere y’insinga za MI ishobora kunoza imikorere yo gushyiraho, ariko nanone yongera ubukana bw’ibikoresho n’inganda.
Porogaramu zisanzwe
Bitewe n’imikorere yayo myiza y’insinga zirinda umuriro, insinga ya MI ikoreshwa cyane mu nyubako ndende zirinda inkongi, ibikorwa remezo by’inzira za gari ya moshi, ibikorwaremezo binini bya rubanda, n’ahantu hafite ubushyuhe bwinshi n’ibyago bishobora gushya.
Muri izi porogaramu, imikorere ihamye ya sisitemu yayo y'ibikoresho by'insinga ituma umuriro uhoraho utangwa mu gihe cy'umuriro cyangwa mu bihe bikomeye, bigatuma iba igisubizo cy'ingenzi kuri sisitemu z'amashanyarazi zikoreshwa mu gutwara imizigo.
Umwanzuro: Icyerekezo cy'iterambere ry'ibikoresho by'insinga
Ukurikije uko ibikoresho by’insinga bigenda bitera imbere, insinga za MI zigaragaza impinduka ikomeye kuva ku bikoresho by’insinga zikoreshwa mu gukingira ibidukikije kugera ku bikoresho by’insinga zikoreshwa mu gukingira ibidukikije.
Ku batanga ibikoresho by'insinga, ubushobozi bwo kugenzura ubuziranenge, ingano y'uduce duto, ubushobozi bwo kwirinda ubushuhe, n'imiterere y'amazi ya magnesium oxyde (MgO insulation), hamwe n'uburyo buhoraho bwo gutanga ibikoresho by'umuringa n'icyuma gikingira umuringa, bizaba ari ibintu by'ingenzi mu guhatana ku isoko ry'ibikoresho by'insinga bidashobora gushya.
Dukomeje kwibanda ku bikoresho bifitanye isano n’insinga, dushyigikira abakiriya mu gukoresha insinga za MI n’izindi nsinga zikora neza kandi zirinda umuriro.
