Ib qho kev sib xyaw insulator muaj peb yam: core pas nrig, silicone rubber shed vaj tsev thiab kawg fittings. Raws li lub load-cov kabmob puab lub cev, cov tub ntxhais qws ua haujlwm tsib lub luag haujlwm hauv qab no:

1. Mechanical Load Bearing (Core Function)

Nws dais tag nrho cov tensile loads nrog rau cov induced los ntawm conductors, fittings, ice coatings, cua siab thiab seismic kev ua ub no, ua raws li ib tug load- nqa ib feem ntawm lub insulator.

Nws txuas txuas txuas txuas txuas txuas ntxiv thiab cov neeg siv hluav taws xob kom tau raws li qhov xav tau ntawm kev nruj thiab kev ncua lub zog rau cov kab hla thiab ntev - ncua kev hla.

Nws nta lub zog tshwj xeeb (lub teeb yuag thiab lub zog tensile ntau dua li porcelain lossis iav), uas txo qhov hnyav ntawm cov kab sib kis.

2. Hluav taws xob rwb thaiv tsev (Basic Electrical Function)

Fabricated los ntawm epoxy resin iav fiber reinforced yas (FRP), cov tub ntxhais pas nrig nws tus kheej yog ib qho siab -cov khoom siv insulating:

Nws thaiv fais fab - zaus ntws tam sim no ntawm siab -voltage conductors thiab grounded towers.

Nws muab cov rwb thaiv tsev tseem ceeb hauv tsev, thiab ua haujlwm hauv kev sib koom tes nrog cov khoom siv silicone roj hmab sab nrauv kom paub txog kev sib cais hluav taws xob ntawm theem thiab nruab nrab ntawm theem thiab hauv av.

3. Kev hloov hluav taws xob thiab kev sib koom ua ke

Nws homogenizes cov hluav taws xob sab hauv hluav taws xob faib hluav taws xob ntawm lub insulator kom tsis txhob muaj lub zog hauv zos ntau dhau uas yuav ua rau corona tawm thiab tawm ib nrab.

Nws inhibits internal breakdown channels tsim los ntawm huab cua sib txawv thiab interfacial tsis xws luag, thiab txhim kho lub zuag qhia tag nrho breakdown voltage kuj.

4. Moisture thiab Internal Breakdown Barrier

The dense solid FRP core rod prevents rainwater, moisture and polluted gas from penetrating into the insulator interior through end fittings:

Nws zam txoj hauv kev tsim los ntawm cov dej noo ingress, yog li tiv thaiv cov tub ntxhais qws brittle puas thiab sab hauv deg tawg.

Ua ke nrog qhov kawg sealing qauv, nws thaiv cov channel rau hydrolysis thiab acid corrosion kom qeeb kev laus.

5. Kev them nyiaj yug tus qauv tsim

Raws li lub cev pob txha nruj, nws txhawb nqa cov roj hmab silicone sab nraud:

Nws tiv thaiv kev deformation thiab kev sib tsoo ntawm lub tsev nyob hauv qab cua siab thiab kub siab.

Nws tuav qhov ncaj thiab qhov ntev stability ntawm tag nrho cov insulator, thiab khaws cov txheej txheem creepage nrug ntawm sab nraud rwb thaiv tsev tiv thaiv deformation.

Ntxiv Distinction: Core Qws vs. Silicone Rubber Shed Tsev

Core Rod: Pem hauv ntej tivthaiv, lub luag hauj lwm rau mechanical load bearing thiab lub ntsiab rwb thaiv tsev.

Silicone Rubber Shed Tsev: Cov khoom siv sab nrauv, mob siab rau los tiv thaiv- pa phem flashover, creepage nrug ncua ntxiv, huab cua tsis kam thiab UV tsis kam, tsis muaj peev xwm loj tensile.

Cov khoom tseem ceeb uas yuav tsum tau muaj

Txhawm rau ua kom tiav cov haujlwm saum toj no, tus pas nrig tseem ceeb yuav tsum muaj lub zog tensile siab, tsis tshua muaj dej nqus, hydrolysis tsis kam, hluav taws xob yaig tsis kam, siab ntim resistivity, khoov tsis kam thiab tiv thaiv -kev ua haujlwm nkag.
