1.Thiab Xhhw hlau: muaj pes tsawg leeg thiab cov yam ntxwv tseem ceeb
XHhw xaim yog ib hom qauv hluav taws xob insulated nrog tus kab mob sib txuas nrog polyethylene rau nws cov khoom siv hluav taws xob, thiab lub zog siv zog. Daim ntawv "XHHW" qhia tias nws cov kev haum rau kev siv cov chaw qhuav thiab ntub dej hauv chav dej ntub, nyob ntawm cov chaw qhuav, nyob ntawm qhov tshwj xeeb.
1.1 Qhov Zoo ntawm XHHW HLAU
Cov Kub Kub Kuj
XHHW rwb thaiv tsev nrog cov cua sov huab cua sov, ua rau nws zoo tagnrho rau lub zog hluav taws xob uas high pib ua haujlwm kom ua haujlwm nrawm dua. Cov cuab yeej no minimizes kev pheej hmoo ntawm rwb thaiv tsev degradation nyob rau lub sijhawm.
Dej noo thiab tshuaj lom neeg tsis
XLPE rwb thaiv tsev muab kev tiv thaiv zoo heev rau dej, roj, acids, thiab alkalis, ua kom muaj kev txhim kho txhim kho hauv kev lag luam lossis sab nraum zoov lub cev muaj chaw.
Durability thiab hloov tau
XHhw Hlau tswj tau yooj yim ntawm tsawg kub, yooj yim installation hauv cov chaw nruj lossis cov teeb meem nyuaj. Nws cov kev tsim kho tau zoo tiv thaiv puas, txiav, thiab cuam tshuam kev puas tsuaj.
Ua raws li cov qauv
XHhw xaim sib ntsib los yog ntau dua cov qauv xws li UL 44, NEC (Nom) Kev Yuav Tsum Ua Haujlwm Kev Lag Luam Kev Lag Luam, thiab siv.
2.xhhw xaim hauv lub cev muaj zog ncig: vim li cas nws yog qhov kev xaiv ntse
Lub cev muaj zog nrog cov neeg coj tau muaj peev xwm tuav qhov siab pib (Inrush tee, thiab thau khoom lag luam. Ntawm no yog li cas xhhw hlau txawj nyob rau hauv cov ntawv thov no:
2.1 kev siv cov khoom siv siab tam sim no
Cov Motors, tshwj xeeb tshaj yog cov neeg muaj cov, xav tau cov neeg saib xyuas uas muaj kev cuam tshuam tsawg tsawg los txo lub zog poob. Tooj liab xhhw xov hlau nyiam4 / 0 xhhw -2 tooj liab hlauthiab2 / 0 xhhw hlauKev muab kev coj ua zoo dua, ua kom pom kev zoo. Piv txwv li:
4 / 0 xhhw -2 tooj liab hlau(AWG 4 / {0) tuaj yeem nyab xeeb nqa mus txog 260 amps ntawm 75 degree, ua kom haum rau hnyav-ua haujlwm.
500mcm mcm xhhw(500 kcmil) aluminium lossis tooj liab cov qauv yog qhov zoo tagnrho rau cov neeg muaj peev xwm loj, xws li cov neeg hauv hvac system lossis manufacturing nroj tsuag.
2.2 Kev Tswj Hluav Taws Xob
Tus ntoo khaub lig-txuas Polyethylene rwb thaiv tsev hauv XHHW hlau tiv thaiv overheating thauj txawm tias nyob rau hauv kev thauj khoom. Qhov no yog qhov tseem ceeb rau cov motors ua haujlwm nyob ib puag ncig zoo li cov chaw tsim khoom lossis cov chaw nres tsheb, qhov chaw huab cua kub muaj ntau.
2.3 Versatility hla lub cev muaj zog
XHhw Hlau yog sib haum nrog ntau lub zog tsim muaj zog, suav nrog:
Ib leeg-theem thiab peb-theem motors
Submersible twj (ua tsaug rau nws cov dej tsis kam)
High-Torque motors hauv conveyor tshuab lossis compressors
