Ib leeg tub ntxhais Aluminium 6.35 / 11kV Nruab Nrab Voltage Fais Fab Cable

.6.35/11kV nruab nrab voltage fais fab cable muaj ib lub tsho armored uas tiv thaiv lub cable los ntawm kev tawm tsam sab nraud. Armoring yuav tsum tau siv nyob rau hauv tag nrho cov mechanically corrosive installation. Lub tsho sab hauv muaj cov hlau xaim lossis cov hlua khi ua armor. Lub tsho sab nrauv tiv thaiv cov xov hlau los ntawm kev puas tsuaj rau txhua yam thiab tshuaj lom neeg, thiab nws cov xim sib sib zog nqus liab txheej yog impermeable rau dej, huab cua, cuam tshuam thiab puas.

yam ntxwv

Aluminium MV fais fab cables yog dav siv nyob rau hauv ntau daim ntawv thov vim lawv muaj peev xwm rau reliably xa nruab nrab voltage zog. Piv txwv li, kev faib khoom siv hluav taws xob; Kev siv hluav taws xob tauj dua tshiab, rau kev sib txuas cov tshuab hluav taws xob, hloov pauv, thiab kab sib txuas; nyob rau hauv loj industrial chaw; infrastructure, thiab vaj tse, xws li tunnels, tshav dav hlau, railways, thiab kev loj, thiab lwm yam.

Feature

• Tus neeg xyuas pib: Stranded Compacted Circular aluminium conductor raws li AS / NZS 1125

• Conductor Screen: Extruded Semi-conductive compound

• Rwb thaiv tsev: XLPE

• Rwb thaiv tsev Screen: Extruded

• Kev thaiv dej Longitudinal: Dej thaiv daim kab xev saum toj thiab hauv qab strippable Semi-conductive compound

tooj liab screen (yeem)

• Hlau Rwb thaiv tsev Screen: Copper Wire Screen + helically siv tooj liab daim kab xev (E / F tam sim no muaj peev xwm - Raws li yuav tsum tau)

• Metallic Sheath: Lead Alloy (yeem)

• Txheej txheej: Extruded Polyvinyl Chloride, Xim: Dub

(Alternative Sheath: PVC + HDPE Composite Sheath lossis LSZH Cov ntaub qhwv sab nraud thiab cov ntsuas yuav hloov raws li)

Daim ntawv pov thawj

Nruab nrab voltage fais fab cable yog SAA certified, uas muaj anti-UV txheej sheath, zoo heev siab tsis kam thiab sab nraud quab yuam kuj, corrosion kuj, thiab laus kuj. Nws yog qhov tsim nyog rau kev xa hluav taws xob thiab kev faib tawm hauv cov phiaj xwm kev tsim vaj tsev, kev tso hauv av, kev tso sab nraum zoov thiab lwm yam xwm txheej.

Cov kab ntau lawm

Greater Wire chaw tsim tshuaj paus muab cov kev pab cuam khoom customized. Raws li tus neeg siv khoom xav tau qhov project, nws tuaj yeem muab cov kev xav tau rau cov khoom siv hluav taws xob, cov ntaub ntawv rwb thaiv tsev, cov ntaub ntawv sheath, xim, thiab lwm yam. Lub Hoobkas ua tau raws li cov kev xav tau los ntawm kev hloov pauv ntau lawm. Piv txwv li, qee cov ntawv thov kev lag luam xav tau cov cable tshwj xeeb uas tiv taus qhov kub thiab txias, lossis kev tsim kho yuav tsum muaj cov kab hluav taws xob tsis muaj halogen thiab tsis muaj pa taws. Lub Hoobkas tuaj yeem tsim cov khoom siv cable sib xws raws li cov kev xav tau tshwj xeeb. Cov kev pabcuam Customized pab cov chaw tsim khoom kom ua tau raws li tus kheej xav tau ntawm cov neeg siv khoom thiab txhim kho kev lag luam kev sib tw. Txhawm rau kom ntseeg tau tias qhov txuas ntxiv ntawm cov txheej txheem tsim khoom, Cov Hlau Hlau feem ntau tswj xyuas qee yam ntawm cov khoom siv raw khoom, xws li tooj liab, txhuas, cov ntaub ntawv rwb thaiv tsev, thiab cov ntaub ntawv sheath. Nyob rau tib lub sijhawm, kev tswj cov khoom lag luam ntawm cov cables tiav kuj tseem ceeb heev. Lub Hoobkas yuav tsum tau npaj cov khoom tiav cov khoom tiav raws li kev txiav txim siab thiab kev ua lag luam kwv yees kom tsis txhob muaj ntau dhau lossis tsis txaus ntawm cov khoom muag.

FAQ

Q: Yuav ua li cas nrog nruab nrab voltage fais fab cable overload?

A: Thaum nruab nrab voltage fais fab cable yog overloaded, tam sim no load yuav tsum tau txo tam sim ntawd. Lub sij hawm ntev overload yuav ua rau cable overheating thiab rwb thaiv tsev puas, thiab lub cable cross-section yuav tsum tau nce los yog kub dissipation yuav tsum tau txhim kho.

Q: Kev kho hauv zos ntawm MV cable yog dab tsi?

A: Kev kho hauv zos ntawm MV cable yog los kho cov rwb thaiv tsev hauv zos los ntawm kev siv cov cua sov shrink tubing los yog txias shrink tubing los kho cov rwb thaiv tsev ntawm cov cable.

Q: Yuav ua li cas xaiv nruab nrab voltage cables haum rau underground nteg?

A: Cov kab hluav taws xob nruab nrab uas tsim nyog rau kev tso hauv av yuav tsum muaj lub zog txhua yam, tsis muaj dej tsis kam thiab corrosion kuj. Armored cables lossis cables nrog cov txheej txheem noo noo yog qhov kev xaiv ntau.
