PS / PSN 25-66KV 3-12.5KN Post hom porcelain insulator rau sab nraum zoov high voltage Fais fab kab

Porcelain post insulators rau high-voltage kab Ib kab ncej insulator yog steel insulator uas muaj ib los yog ntau tshaj insulators tas mus li glued rau ib tug hlau puag, tej zaum nrog ib tug cap, thiab yuav ua tau ob npaug rau mounted rau ib tug hlau puag.Lub taub hau ntsia liaj qhov rooj los yog ib qho los yog ob peb lub bolts yog rigidly mounted rau ntawm tus qauv txhawb nqa.Nws yog siv rau insulating thiab txhawb cov xov hlau nyob rau hauv AC fais fab kab nrog ib tug nominal voltage siab tshaj 1000V, ib zaus tsis siab tshaj 100Hz, thiab qhov siab tshaj tsis siab tshaj 1000m.ntawm 40 ° C.Kab (khoom) ncej insulators tuaj yeem hloov tus pin insulators.Pin insulators yog B-hom insulators, uas yog nquag ua kom puas thiab puas thaum ua haujlwm.Toughened iav insulators yuav ua rau nws tus kheej puas nyob rau lub sijhawm no, thaum cov porcelain insulators yuav tsis.Yog li ntawd, lub tuam txhab kev lag luam hluav taws xob yuav siv ntau lub zog thiab cov khoom siv los ua kev soj ntsuam hluav taws xob thiab kev tiv thaiv kev ntsuas ntawm cov plooj (porcelain insulators), uas muaj qee qhov tsis zoo ntawm kev lag luam thiab kev nyab xeeb ntawm cov khoom siv hluav taws xob.Yog li ntawd, nrog kev txhim kho ntawm kev tsim technology, kab (khoom) post insulators tshwm sim.Cov insulator no muaj cov khoom siv insulator thiab yog hom A insulator, yog li tsis tas yuav txhawj xeeb txog kev tawg ntawm sab hauv ntawm insulator thaum ua haujlwm, uas yog qhov zoo ntawm nws.
Kab pillar porcelain insulators tau muab faib ua yim qib ntawm 95, 105, 125, 150, 170, 200, 250 thiab 325kV raws li qhov ntsuas hluav taws xob impulse withstand voltage tus nqi;Raws li qhov ntsuas qhov ntsuas tsis ua haujlwm load, lawv muab faib ua 3, 5, 8 thiab 12.5kN Plaub qib;Raws li txoj kev teeb tsa, nws tau muab faib ua ob hom: ntsug installation thiab kab rov tav installation;Raws li txoj kev sib txuas nrog high-voltage xov hlau, nws muab faib ua ob hom: sab saum toj khi hom thiab sab saum toj clamp hom;Raws li txoj kev sib txuas ntawm cov hlau ko taw thiab lub hauv paus, nws tau muab faib ua detachable Hom (xov kev sib txuas) thiab inseparable hom ob.
