Cable accessories khoom taw qhia

Txoj kev sib txuas
Txoj kev sib txuas ntawm cov khoom siv cable feem ntau muab faib ua qhov txuas txuas thiab nruab nrab kev sib txuas. Terminal kev twb kev txuas yog muab faib ua lub davhlau ya nyob twg sab hauv tsev thiab sab nraum zoov davhlau ya nyob twg. Feem ntau, sab nraum zoov davhlau ya nyob twg hais txog qhov qhib-cua cable sib koom ua ke, thiab sab hauv lub davhlau ya nyob twg yog hais txog kev sib koom ua ke ntawm sab hauv kev sib txuas cable thiab khoom siv hluav taws xob; intermediate kev twb kev txuas yog muab faib ua ncaj-los ntawm hom thiab insulated hom.

Cov cuab yeej txhawb nqa
Cov txheej txheem kev pov hwm zoo no yuav tsum tsawg kawg suav nrog cov hauv qab no:
(1) Ua ntej tawm hauv lub Hoobkas, cov khoom tseem ceeb (xws li roj hmab kev ntxhov siab lub khob hliav qab, epoxy resin lub tes tsho ntawm GIS, impregnation tus neeg sawv cev, prefabricated qhov nruab nrab ntawm cov pob qij txha, thiab lwm yam) yuav tsum tau kuaj nruj me ntsis. Ua tib zoo xyuas seb qhov ntsuas thiab ntsuas cov cuab yeej puas ntseeg tau, seb txoj kev xeem puas muaj txiaj ntsig, seb cov neeg ua haujlwm xeem puas tau kawm zoo, thiab seb cov ntaub ntawv xeem puas tiav;
(2) Txawm hais tias lub installation thiab kev tsim kho cov neeg ua haujlwm xa los ntawm cov chaw tsim khoom tau raug cob qhia nruj me ntsis thiab muaj kev tsim kho txaus;
(3) Txawm hais tias kev sib koom tes ntawm cov chaw sib txawv ntawm cov chaw tsim khoom yog qhov zoo;
(4) Cov ntaub ntawv muag khoom thiab kev ua haujlwm dhau los.

Accessory hom
Cable accessories muaj ntau hom, muaj ntau hom ntawm cov yam ntxwv thiab kev txwv, thiab feem ntau tsis tuaj yeem hloov ib leeg. Cov uas nquag muaj raws li nram no:
(1) Wrapping hom: Cable accessories ua los ntawm wrapping on-site nrog roj hmab strips (self-adhesive) yog hu ua qhwv cable accessories. Cov khoom siv zoo li no yooj yim rau loosen, muaj hluav taws tsis zoo thiab lub neej ua haujlwm luv luv;
(2) Casting type: Ua los ntawm kev nchuav rau ntawm qhov chaw nrog thermosetting resin ua cov khoom tseem ceeb. Cov ntaub ntawv xaiv muaj xws li epoxy resin, polyurethane, acrylate, thiab lwm yam. Qhov tsis zoo ntawm cov khoom siv no yog cov npuas tau yooj yim tsim thaum kho;
(3) Moulding hom: Feem ntau yog siv rau cable intermediate kev twb kev txuas, molded thiab rhuab rau ntawm qhov chaw, kev sib txuas nrog lub cable. Cov txheej txheem tsim khoom ntawm cov khoom siv no yog qhov nyuaj thiab siv sijhawm ntev, thiab nws tsis haum rau cov pob qij txha hauv lub davhlau ya nyob twg;
(4) Cold shrinkage type: Silicone roj hmab, EPDM roj hmab thiab lwm yam elastomers yog pre-expanded nyob rau hauv lub Hoobkas thiab yas txhawb strips ntxiv rau lawv. Thaum lub sij hawm tsim kho ntawm qhov chaw, cov kev txhawb nqa strips tau rub tawm los ua kom cov yeeb nkab shrinkage ntawm cov kab hauv qab cov nyhuv elastic ntawm cov roj hmab los tsim cov khoom siv cable. Cov khoom siv no zoo tshaj plaws rau cov chaw tsim kho uas tsis tuaj yeem ua kom sov los ntawm cov nplaim taws, xws li mines, petrochemicals, thiab lwm yam.;
(5) Thaum tshav kub kub shrinkage hom: Roj Hmab-yas alloy yog tsim los rau hauv "zoo li lub cim xeeb nyhuv" Cov khoom siv yog ua los ntawm cov khoom sib txawv thiab yog rhuab thiab shrunk ntawm cable ntawm qhov chaw. Cov khoom siv yog cov yam ntxwv ntawm lub teeb yuag, kev tsim kho yooj yim thiab yooj yim, txhim khu kev lag luam thiab tus nqi qis;
(6) Prefabricated: Silicone roj hmab yog txhaj rau hauv cov khoom sib txawv, vulcanized thiab tsim nyob rau hauv ib lub sij hawm, tsuas yog qhov kev sib txuas lus yog khaws cia, thiab cov khoom siv tau muab tso rau hauv cable thaum lub sij hawm tsim kho. Cov txheej txheem kev tsim kho no txo ​​cov yam tsis zoo ntawm ib puag ncig mus rau qhov tsawg kawg nkaus, yog li cov khoom siv muaj peev xwm siv tau zoo thiab yog cov kev taw qhia ntawm kev sib txuas ntawm cov kab txuas txuas, tab sis cov cuab yeej tsim khoom yog qhov nyuaj thiab muaj ntau yam kev qhuab qhia thiab kev lag luam. Cov khoom siv ntawm cov khoom siv prefabricated hauv qab peb-txoj kev sib tshuam thiab qhov chaw nres nkoj ntawm lub cable tseem yog cov ntaub ntawv kub-shrinkable, yog li lawv yog ib qho ua ke ntawm prefabricated thiab tshav kub-shrinkable.

Cov khoom uas txuas cov cables rau cov kab sib kis thiab cov kab sib txuas thiab cov khoom siv sib txuas
Qhov kev nkag no yog tshuaj xyuas los ntawm "Science Popularization China" Science Encyclopedia Nkag Sau thiab Daim Ntawv Thov Ua Haujlwm Project.
Fais fab cable accessories (Lus Askiv lub npe: Cable Accessories yog cov khoom uas txuas cables mus rau lub hwj chim kis tau tus mob thiab tis kab thiab muaj feem xyuam rau lub hwj chim faib khoom. fais fab kis tau tus mob cable accessories feem ntau yog raws li cov yam ntxwv ntawm cov qauv cable lawv tuaj yeem tsis tsuas yog kho qhov kev ua tau zoo ntawm cov cables, tab sis kuj xyuas kom meej qhov txuas txuas ntawm cable ntev thiab lub davhlau ya nyob twg kev ntseeg siab ntawm high-voltage cable accessories yuav raug txiav txim los ntawm cov yam xws li hluav taws xob kev ua tau zoo, sealing thiab ya raws-pov thawj kev ua tau zoo, mechanical kev ua tau zoo thiab cov txheej txheem kev ua tau zoo.
