Porcelain insulators tau siv thawj zaug hauv xov tooj hauv xyoo 1849. Nyob rau xyoo 1990, kev tsim thiab ua tiav ntawm cov plooj (porcelain insulators) hauv Suav teb tau vam khom rau ntawm phau ntawv hammering. Nyob rau hauv lub xyoo pua 21st thaum ntxov, kom ua tau raws li qhov xav tau ntawm ultra- high voltage (UHV) kev tsim kho, cov tuam txhab hauv tsev tau pib ua haujlwm thev naus laus zis. Xyoo 2010, cov tuam txhab xws li Sinoma Electric Porcelain tau txais kev txhim kho ntawm UHV pas nrig- zoo li cov insulators. Los ntawm kev txhim kho cov txheej txheem, lawv ua tiav qhov siab dhau ntawm cov khoom megavolt, thiab cov khoom lag luam tau ua tiav hauv cov haujlwm thaum ntxov xws li Jin-Southeast-Nanyang-Jingmen 1000 kV UHV AC kev sim ua qauv qhia, rhuav tshem cov kev lag luam txawv teb chaws.
Cov txheej txheem ntau lawm tom qab underwent innovation, los ntawm "dag ca rau ntuj huab cua kom qhuav" mus rau "ntim hluav taws xob cua ziab," ho txhim kho noo noo uniformity thiab ntau lawm efficiency. Lub rooj cob qhia tau qhia cov cuab yeej ntse xws li ob lub-chaw nres tsheb puv tsis siv neeg dawb huv- tshuab tiav, paub txog kev hloov pauv los ntawm phau ntawv hammering mus rau kev tsim khoom ntse. Los ntawm kev tsim ib lub chaw tshawb fawb thiab kev loj hlob thiab nce R & D peev, tuam txhab uas muag tau kov yeej cov kev cov nyom nyob rau hauv cov cheeb tsam xws li 550 kV thiab saum toj no Circuit Court breaker resistance sheets, thiab 750 kV thiab 1000 kV inorganic bonded hollow porcelain insulators, sau cov khoob hauv tsev. Sinoma Porcelain Insulators tau tsim ib qho loj - nplai, tag nrho cov kab ntau lawm thiab ntse tswj kev tsim khoom rau ultra-siab voltage thiab ntxiv- high voltage insulators.
Tam sim no, Tuam Tshoj tus plooj (porcelain insulator) thev naus laus zis tau mus txog theem thoob ntiaj teb, tsim cov khoom lag luam matrix npog tag nrho cov qib voltage ntawm 10kV rau ± 1100kV. Cov khoom tsim hauv tsev tau ua tiav rau cov haujlwm tseem ceeb hauv tsev thiab thoob ntiaj teb xws li Changji-Guquan ±1100kV ultra-high voltage direct tam sim no project transmission and the Belo Monte ± 800kV ultra-high voltage transmission line in Brazil. Sinoma Porcelain Insulators tau dhau los ua tus tsim nyog suav cov khoom siv hluav taws xob rau Italian lub teb chaws daim phiaj, Terna, thiab nws cov xiav - grey glaze thiab lwm yam khoom lag luam raug xa tawm mus rau ntau tshaj 20 lub teb chaws thiab cheeb tsam thoob ntiaj teb.
