Amashanyarazi(nanone bita insulatrice composite cyangwa nonceramic insulator) igizwefiberglass

inkoni ifatanye ibyuma bibiri byanyuma bitwikiriwe na rebero ikirere.Polymer

insulator zakozwe bwa mbere mu myaka ya za 1960 zishyirwaho muri za 1970.

Imashini ya polimeri, izwi kandi nka insulator ikora, itandukanye na insulator

muburyo bigizwe na polymer yimvura itagira imvura na mandel yibikoresho bya resin.Ni

kurangwa no kutoroha kwegeranya amazi, kurwanya cyane ububi nuburemere bworoshye.Kuri

ubungubu, Ubuyapani ntabwo buteza imbere ikoreshwa rya gari ya moshi zifite amashanyarazi gusa, ahubwo n’urwego rw’amashanyarazi,

kandi byitezwe ko bizahinduka ibikoresho bishya (kuri catenary) mugihe kizaza.

Porogaramu

Abayobora imirongo y'amashanyarazi yo hejuru barahujwe kandi bagashyirwa kumunara na insulator

n'ibikoresho.Insulator zikoreshwa mugukingira insinga niminara ntigomba kwihanganira gusa

igikorwa cya voltage ikora, ariko kandi ikorerwa nigikorwa cya overvoltage mugihe ikora,

kandi nanone yihangane ibikorwa byingufu za mashini, impinduka zubushyuhe ningaruka za

ibidukikije bikikije ibidukikije, bityo insulator igomba kuba imeze neza.Indangabintu na

imbaraga za mashini.Mubisanzwe, ubuso bwa insulator burimo gukonjeshwa.

Ibi ni ukubera ko: Ubwa mbere, intera yamenetse (izwi kandi nka creepage intera) ya insulator

irashobora kwiyongera, kandi buri mugozi wumurongo urashobora kandi kugira uruhare mukuziba arc;

Iya kabiri ni uko iyo imvura iguye, umwanda utemba uva muri insulator ntuzatemba neza

kuva igice cyo hejuru cya insulator kugeza igice cyo hepfo, kugirango wirinde gushiraho inkingi zanduye

no guteza impanuka zumuzunguruko mugufi, kandi zigira uruhare mukubuza gutembera kwimyanda;

Icya gatatu ni uko iyo umwanda wo mu kirere uguye kuri insulator, kubera ubusumbane bwa

insulator, ibyuka bihumanya ntibizaba bifatanye neza na insulator, biteza imbere kurwanya umwanda

ubushobozi bwa insulator kurwego runaka.Hariho ubwoko bwinshi bwa insulator kumashanyarazi hejuru,

zishobora gutondekwa ukurikije ubwoko bwimiterere, iziritse hagati, uburyo bwo guhuza na

ubushobozi bwo kwihanganira.
