AS/NZS heerka 12.7-22kV-XLPE dahaaran MV Korontada

Tilmaamaha:

    Qaybinta korantada ama fiilooyinka gudbinta hoose ee sida caadiga ah loo isticmaalo sahayda aasaasiga ah ee shabakadaha degaanka ee ganacsiga, warshadaha iyo magaalooyinka.Ku habboon nidaamyada heerka khaladka sare ee lagu qiimeeyay ilaa 10kA/1sec.Dhismayaasha hadda lagu qiimeeyay cilad sare ayaa diyaar ah haddii la codsado.

    Xadhkaha korantada dhexdhexaadka ah ee loo qaabeeyey
    Waxtarka iyo cimri dhererka, fiilada MV kasta waa in lagu habeeyaa rakibaadda laakiin waxaa jira waqtiyo marka fiilo dhab ah loo baahan yahay.Khubaradayada xadhiga MV ayaa kula shaqayn kara si aad u qaabayn lahayd xal u dhigma shuruudahaaga.Inta badan, habayntu waxay saamaysaa cabbirka aagga muraayadda birta ah, taas oo lagu hagaajin karo si loo beddelo awoodda wareegga gaaban iyo bixinta dhulka.

    Xaalad kasta, xogta farsamada ayaa la bixiyaa si ay u muujiso ku habboonaanta iyo qeexida loo habeeyay soo saarista.Dhammaan xalalka la habeeyey waxay ku xiran yihiin tijaabinta la xoojiyey ee Xarunta Tijaabada Cable ee MV.

    La xidhiidh kooxda si aad ula hadasho mid ka mid ah khubaradayada.

Codsiga:

Xadhkaha LSZH MV waxa kale oo ka mid ah fiilooyinka gaashaaman ee PVC hal-core AWA iyo xargaha gaashaman ee XLPE-ga badan ee SWA.
Naqshaddan waxaa caadi ahaan loo adeegsadaa fiilooyinka korantada ee kaaliyaha ee xadhkaha korantada iyo deegaanno kala duwan.Hubka lagu daray waxay ka dhigan tahay in fiilada si toos ah loogu aasi karo dhulka si looga hortago shoog shil ah iyo waxyeelo.
Xadhkaha LSZH way ka duwan yihiin fiilooyinka PVC iyo fiilooyinka laga sameeyay xeryahooda kale.
Marka xadhiggu dab qabsado, waxa uu soo saari karaa xaddi badan oo qiiq madow oo cufan iyo gaas sun ah.Si kastaba ha ahaatee, sababtoo ah fiilada LSZH waxay ka samaysan tahay walxo heerkulbeeg ah, waxay soo saartaa qadar yar oo qiiq ah iyo sunta sunta ah, kuma jiraan wax gaas ah oo acidic ah.
Waxay u sahlaysaa dadka inay ka baxsadaan dab ama meel halis ah.Sidaa darteed, inta badan waxaa lagu rakibaa gudaha gudaha, sida meelaha caamka ah, meelaha kale ee khatarta ah, ama jawi liidata.

Fiilooyinka korantada dhexdhexaadka ah ee loo qaabeeyey:

Waxtarka iyo cimri dhererka, fiilada MV kasta waa in lagu habeeyaa rakibaadda laakiin waxaa jira waqtiyo marka fiilo dhab ah loo baahan yahay.Khubaradayada xadhiga MV ayaa kula shaqayn kara si aad u qaabayn lahayd xal u dhigma shuruudahaaga.Inta badan, habayntu waxay saamaysaa cabbirka aagga muraayadda birta ah, taas oo lagu hagaajin karo si loo beddelo awoodda wareegga gaaban iyo bixinta dhulka.
Xaalad kasta, xogta farsamada ayaa la bixiyaa si ay u muujiso ku habboonaanta iyo qeexida loo habeeyay soo saarista.Dhammaan xalalka la habeeyey waxay ku xiran yihiin tijaabinta la xoojiyey ee Xarunta Tijaabada Cable ee MV.
