Amavuta yo gukingira uruhu, azwi kandi nka irangi cyangwa varnish ikingira uruhu, agira uruhare mu gukingira uruhu, kurwanya ubushuhe, gukwirakwiza ubushyuhe, no gukaraba mu byuma bihindura uruhu bifite umuvuduko mwinshi.
Dukurikije imiterere itandukanye y’ibinyabutabire, amavuta akingira ubushyuhe ashobora kugabanywamo ibice bitatu: ashingiye kuri polyester; ubwoko bwa Resin; ibikoresho bya siliceous. Amavuta akingira ubushyuhe ya polyester ategurwa ahanini binyuze mu buryo bwo guhumeka bwa polyol na polyacide, kandi akenshi ni amazi adafite ibara cyangwa umuhondo woroshye ubonerana. Afite voltage nyinshi yo kwangirika no kwihanganira ingano y’amazi, bishobora kubuza umuriro kunyuramo no gutanga ubushyuhe bwiza. Afite uburyo bwo kugabanya ikiguzi mu bwoko butatu bw’amavuta akingira ubushyuhe kandi ni yo mavuta akingira ubushyuhe akoreshwa cyane mu byuma bihindura ubushyuhe bwinshi.
Ariko, amavuta akingira polyester afite ubushyuhe bwinshi, kandi ubushyuhe bwayo bugira ingaruka zikomeye ku bushyuhe. Ubushyuhe bwiyongera cyane iyo ubushyuhe buri hasi, ibyo bigira ingaruka cyane ku bushyuhe bwayo no ku gushonga k'ubushyuhe. Kubwibyo, iyo ikoreshejwe, akenshi biba ngombwa kongeramo ibinyabutabire kugira ngo igabanye ubushyuhe bw'amavuta akingira, ikomeze kuba nziza, kandi irebe neza ko transformer ifite frequency yo hejuru ishobora kwinjizwa yose mu gihe cyo kwinjizwa. Uburemere bwihariye bw'amavuta akingira polyester n'ibinyabutabire muri rusange ni hafi 0.9, bushobora kugeragezwa hakoreshejwe icyuma gipima uburemere runaka.
Icya kabiri, amavuta akingira polyester ashobora kwangirika no kwangirika mu bushyuhe bwinshi, bigatuma habaho ibintu bihumanya ikirere n'imyanda, ibyo bigira ingaruka ku mikorere isanzwe y'umusaruro kandi bigagabanya ikoreshwa ryawo mu bushyuhe bwinshi. Byongeye kandi, ugereranije n'amavuta akingira resin na siliceous, amavuta akingira polyester afite agaciro kanini k'igihombo cya dielectric, bivuze ko igihombo cy'ingufu kiba kinini mu gihe cy'amashanyarazi asimburana kandi ku rugero runaka kizagira ingaruka ku mikorere y'umusaruro.
Muri iki gihe, amavuta akingira ibidukikije ya polyester akoreshwa cyane mu gutera ibyuma, nka transformers zifite frequency yo hejuru, moteri, insinga, nibindi, bishobora kunoza uburyo bwo gukingira, gutwara ubushyuhe, no kwirinda ubushuhe bw'ibicuruzwa no kongera igihe cyabyo cyo gukora. Amavuta akingira ibidukikije ashingiye kuri resin agizwe ahanini n'ibinyabutabire bya polymeri, akenshi biba mu buryo bw'amazi cyangwa bukomeye, kandi birwanya kwangirika neza.
Amavuta yo gukingira ashingiye kuri resin ashobora gukorwa hakoreshejwe guhindura ingano y'ibikoresho fatizo n'imiterere y'imikorere kugira ngo hakorwe ibinyobwa bya resin bifite ubukana buke. Ibi binyobwa bifite ubushobozi bwo gutemba neza no gutwikira, kandi muri rusange ntibisaba ibindi binyobwa. Mu gihe cy'ubushyuhe, amavuta yo gukingira ashingiye kuri resin ashobora no koroshya cyangwa gushonga. Ugereranyije n'amavuta yo gukingira ya polyester, amavuta yo gukingira resin afite ubukana bwinshi, imikorere myiza yo gukingira amashanyarazi, kandi afite igiciro kiri hejuru. Akoreshwa cyane mu gukingira transformateur zitandukanye, ibyuma by'amashanyarazi, n'imiyoboro. Amavuta yo gukingira ya siliceous agizwe ahanini n'ibinyabutabire bya silicone nka polydimethylsiloxane. Akenshi ni amazi adafite ibara cyangwa umuhondo woroshye kandi afite ubukana buke cyane kandi afite ubukana bwiza.
Ugereranyije n'amavuta ya polyester na resin, amavuta ya siliceous insulation afite agaciro gake k'ibihombo bya dielectric, ingufu nke zitakaza munsi y'amashanyarazi asimburana, ndetse n'imikorere myiza y'ibicuruzwa. Afite kandi ubushobozi bwiza bwo kurwanya arc no kudasohoka, kandi ashobora gukomeza gukora neza mu bidukikije bikomeye. Amavuta ya siliceous insulation ashobora gukoreshwa mu gukingira ahantu hakomeye nko mu kirere gifite amashanyarazi menshi, ubushyuhe bwinshi, ubushuhe bwinshi, n'ubukonje bukabije, bigatuma urwego rwo gukingira rurushaho kuba rwiza kandi imikorere y'ibicuruzwa irushaho kuba myiza. Aho umuriro ucana cyane n'ubushobozi bwo kuzimya ubwabyo biha amavuta ya siliceous insulation inyungu zikomeye mu mutekano w'inkongi. Ariko, amavuta ya siliceous insulation afite ikiguzi kinini kandi muri rusange ntabwo akoreshwa muri transformers zifite frequency nyinshi.
