Iipolymer insulators(ekwabizwa ngokuba yi-composite okanye i-nonceramic insulators) ibandakanyai-fiberglass

intonga edityaniswe kwiintsimbi ezimbini zokuphela kwentsimbi ezigqunywe yirubha yemozulu.Ipolymer

ii-insulators zaqala ukuphuhliswa ngo-1960 kwaye zafakwa kwi-1970s.

I-polymer insulators, eyaziwa ngokuba yi-composite insulators, yahlukile kwi-porcelain insulators

ngokuba zenziwe nge-polymer sheath yobungqina bemvula kunye ne-mandrel yezinto ze-resin.Yi

ebonakaliswe ngokungelula ukuqokelela amanzi, ukuchasana okuphezulu kwi-fouling kunye nobunzima obulula.Nge

ngoku, iJapan ayikhuthazi kuphela ukusetyenziswa koololiwe bombane, kodwa kunye necandelo lamandla,

kwaye kulindeleke ukuba ibe yimathiriyeli entsha yokugquma (yekhathari) kwixesha elizayo.

Usetyenziso

Abaqhubi bemigca yamandla aphezulu baxhunyiwe kwaye bagxininiswe kwinqaba ngama-insulators

kunye nehardware.Ii-insulators ezisetyenziselwa ukugquma iingcingo kunye neenqaba kufuneka zingaxhathisi kuphela

Isenzo sombane osebenzayo, kodwa kwakhona ube phantsi kwesenzo sokugqithisa kakhulu ngexesha lokusebenza,

kunye nokuthwala isenzo samandla oomatshini, utshintsho lobushushu kunye nefuthe le

indawo engqongileyo, ngoko ke i-insulator kufuneka ibe kwimeko entle.iimpawu zokugquma kunye

amandla athile oomatshini.Ngokuqhelekileyo, ubuso be-insulator bubolile.

Oku kungenxa yokuba: Okokuqala, umgama wokuvuza (okwaziwa ngokuba ngumgama we-creepage) we-insulator

inokunyuswa, kwaye i-strand nganye yamaza nayo inokudlala indima ekuthinteleni i-arc;

Okwesibini kukuba xa kunetha, amanzi amdaka ahla ehla kwi-insulator akayi kuhamba ngokuthe ngqo

ukusuka kwindawo ephezulu ye-insulator ukuya kwindawo engezantsi, ukwenzela ukuba ugweme ukubunjwa kweentsika zamanzi amdaka.

kwaye abangele iingozi zendlela emfutshane, kwaye adlale indima ekuthinteleni ukuhamba kwamanzi amdaka;

Okwesithathu kukuba xa izinto ezingcolisa umoya ziwela kwi-insulator, ngenxa yokungalingani

i-insulator, izinto ezingcolisayo aziyi kuqhotyoshelwa ngokulinganayo kwi-insulator, ephucula ukuchasana nongcoliseko.

isakhono se-insulator ukuya kumlinganiselo othile.Kukho iintlobo ezininzi ze-insulators kwiintambo zamandla aphezulu,

enokuthi ihlelwe ngokohlobo lwesakhiwo, i-insulating medium, indlela yokudibanisa kunye

ukuthwala umthamo we-insulator.
