Ma polymer insulators(omwe amatchedwanso composite kapena nonceramic insulators) amakhala ndindi fiberglass
ndodo yomangirizidwa pazitsulo ziwiri zachitsulo zomwe zimakutidwa ndi kachitidwe ka rabara.Polima
ma insulators anayamba kupangidwa mu 1960s ndipo anaikidwa mu 1970s.
Ma polymer insulators, omwe amadziwikanso kuti ma insulators ophatikizika, ndi osiyana ndi zotchingira zadothi
chifukwa amapangidwa ndi polima mvula m'chimake ndi mandrel za utomoni.Zili choncho
yodziwika ndi zovuta kudziunjikira madzi, mkulu kukana fouling ndi kulemera kuwala.Pa
panopa, Japan sikuti ikulimbikitsa kugwiritsa ntchito njanji zamagetsi, komanso gawo lamagetsi,
ndipo ikuyembekezeka kukhala chotchingira chatsopano (cha catenary) mtsogolomo.
Ma kondakitala a mizere yamagetsi apamwamba amalumikizidwa ndikukhazikika pansanja ndi ma insulators
ndi hardware.Ma insulators omwe amagwiritsidwa ntchito potsekera mawaya ndi nsanja sayenera kupirira
mphamvu yamagetsi yogwira ntchito, komanso kukhala ndi vuto la overvoltage panthawi yogwira ntchito,
komanso kunyamula zochita za makina mphamvu, kusintha kutentha ndi chikoka cha
malo ozungulira, kotero insulator iyenera kukhala yabwino.insulation katundu ndi
mphamvu zina zamakina.Nthawi zambiri, pamwamba pa insulator ndi malata.
Izi ndichifukwa: Choyamba, mtunda wotayikira (womwe umadziwikanso kuti mtunda wa creepage) wa insulator
ikhoza kuchulukidwa, ndipo chingwe chilichonse chimatha kugwiranso ntchito poletsa arc;
Chachiwiri ndi chakuti mvula ikagwa, zimbudzi zotsika kuchokera ku insulator sizidzayenda mwachindunji
kuchokera kumtunda kwa insulator kupita kumunsi, kuti mupewe kupanga mizati ya zimbudzi.
ndi kuyambitsa ngozi zazifupi, ndikuchitapo kanthu potsekereza kutuluka kwa zimbudzi;
Chachitatu ndi chakuti pamene zoipitsa mlengalenga zigwera pa insulator, chifukwa cha kusagwirizana kwa mpweya.
insulator, zoipitsa sizingagwirizane ndi insulator, zomwe zimathandizira kudana ndi kuipitsa.
luso la insulator pamlingo wina.Pali mitundu yambiri ya ma insulators a zingwe zamagetsi zam'mwamba,
zomwe zitha kugawidwa molingana ndi kapangidwe kake, sing'anga yotsekereza, njira yolumikizira ndi
kunyamula mphamvu ya insulator.
