High Voltage 70kn Disc Ncua Toughened iav Insulator U70BL

High Voltage 70kn Disc Suspension Toughened iav Insulator U70BL Featured duab

Lus piav qhia luv luv:

Cov qauv ntawm iav insulator zoo ib yam li cov porcelain insulator, tshwj tsis yog tias cov insulator yog iav.Cov ntaub ntawv tseem ceeb ntawm iav insulator yuav tsum muaj xws li quartz xuab zeb, feldspar, limestone, dolomite, soda tshauv, potassium carbonate, thiab lwm yam tempered iav tsim los ntawm cov yam ntxwv ntawm iav insulator yog homogeneous silicate, lub sab hauv microstructure uniformity zoo dua li ntawm hluav taws xob porcelain, thiab muaj zog dielectric zoo dua.Nyob rau tib lub sij hawm, qhov saum npoo ntawm tempered iav muaj prestress thiab zoo heev thermal stability

3 Kev teeb tsa

3.1 Saib xyuas
Cov insulators yuav tsum tau soj ntsuam ib tug los ntawm ib tug raws li tshooj 28 ntawm GB / T1001.1-2003 thiab cov qauv no ua ntej kev teeb tsa, thiab kev siv cov insulators uas tsis ua raws li cov cai saum toj no yuav tsum raug txwv.

3.2 Insulator kuj ntsuas
Rwb thaiv tsev tsis kam ntawm porcelain insulators yuav tsum ntsuas ib los ntawm ib qho ua ntej installation.Insulators uas tsis ua raws li cov cai ntawm DLT626 yuav tsum tsis txhob siv.

3.3 Kev ceev faj
Thaum lub sij hawm installation, cov insulators yuav tsum tau ua tib zoo saib xyuas, tsis txhob muab pov tseg, thiab tsis txhob muaj kev sib tsoo thiab kev sib txhuam nrog cov khoom ntse.

4 Kev ua haujlwm thiab kev tu
4.1 cov ntaub ntawv
Chav ua haujlwm yuav tsum tsim cov ntaub ntawv insulator raws li DL/T 626.

4.2 kev saib xyuas
Thaum lub sij hawm soj ntsuam thiab tshuaj xyuas cov insulators, yog tias nws pom tias lub xauv pin ploj lawm los yog lub insulator muaj pes tsawg tus nqi, nyob rau hauv lub lag luam los yog lub hwj chim tsis ua hauj lwm kho yuav tsum tau saws, thiab cov insulators yuav tsum tau soj ntsuam nyob rau hauv lub sij hawm raws li cov kev cai nram qab no.
Yog tias ib qho ntawm cov xwm txheej hauv qab no tshwm sim, lub insulator tuaj yeem txiav txim siab tias tsis raug.A) Cov kab nrib pleb thiab cov kab daj daj tshwm rau ntawm lub hau hlau (acid reflux);B) Khoov thiab tawg ntawm cov ko taw steel;C) Kev kub hnyiab ntawm cov hlau hau thiab steel ko taw;
D) hlau hau, rwb thaiv tsev thiab steel ko taw tsis nyob rau tib axis: e) porcelain tawg;
F) Rwb thaiv tsev qhov chaw raug kub hnyiab los ntawm kev tso tawm ib nrab thiab ib nrab los ntawm qhov tshwm sim;G) Cov kab nrib pleb lossis skew tshwm hauv cov cement ntawm lub ko taw steel;
H) Corrosion ntawm steel taw tshwm sim raws li tau piav qhia hauv DLT626-2005.
