Kev txhais ntawm kab

Lus Txhais 1: ib lub xov hlau ua los ntawm ib los yog ntau tshaj qhov sib txuas insulated conductors thiab ib txheej insulating tiv thaiv txheej uas xa hluav taws xob los yog cov ntaub ntawv los ntawm ib qho chaw mus rau lwm qhov.

Lus Txhais 2: feem ntau muaj ob peb lossis ntau pawg ntawm cov xov hlau (tsawg kawg) ob ntawm txhua pab pawg ntawm cov hlua sib tw xws li cable, insulated ntawm txhua pab pawg ntawm cov hlau, twist thiab feem ntau tig mus ncig ntawm ib qho chaw, lub khob cij muaj txheej txheej insulating heev. Lub cable muaj cov yam ntxwv ntawm cov khoom siv hluav taws xob sab hauv thiab cov rwb thaiv tsev sab nraud.

kev faib tawm

Cables yog fais fab cable, tswj cable, them cable, shielded cable, kub kub cable, computer cable, teeb liab cable, coaxial cable, hluav taws kub-resistant cable, Marine cable, mine cable, aluminium alloy cable thiab hais txog. Lawv yog tsim los ntawm ib leeg lossis ntau txoj hlua ntawm cov hlau thiab cov rwb thaiv tsev uas siv los txuas cov circuits, cov khoom siv hluav taws xob, thiab lwm yam.

Raws li qhov system ntawm qhov chaw nres tsheb fais fab photovoltaic, cov cables tuaj yeem muab faib ua dc cables thiab ac cables, uas tau faib raws li hauv qab no raws li USES sib txawv thiab siv ib puag ncig:

1. Dc kab

(1) series cables ntawm cov khoom thiab cov khoom siv.

(2) cov kab sib txuas ntawm thiab nruab nrab ntawm pawg mus rau dc faib lub thawv (lub thawv sib txuas).

(3) cable ntawm dc faib lub thawv thiab inverter.

Cov cables saum toj no yog tag nrho cov dc cables, nrog rau ntau qhov chaw sab nraum zoov. Lawv yuav tsum muaj dej noo- pov thawj, hnub ci- pov thawj, txias- tiv taus, tshav kub- tiv taus thiab ultraviolet resistant.

2. Ac kab

(1) Kev sib txuas cable los ntawm inverter rau booster transformer.

(2) qhov kev sib txuas cable ntawm lub zog hloov pauv thiab cov khoom xa tawm.

(3) Kev sib txuas cables los ntawm cov khoom siv hluav taws xob xa mus rau lub zog hluav taws xob lossis cov neeg siv.

Qhov no ntawm cable yog ac load cable, uas yog ntsia rau hauv ib puag ncig sab hauv tsev. Nws tuaj yeem raug xaiv raws li cov kev cai dav dav ntawm kev xaiv fais fab cable.

qauv

Kev sib xyaw thiab ua ntu zus

Cov qauv muaj pes tsawg leeg thiab kev txiav txim ntawm hlau thiab cable yog raws li nram no: [1: qeb, hom phiaj][2: phau ntawv qhia

Lub Cev [3: rwb thaiv tsev][4: puab sheath][5: cov yam ntxwv ntawm cov qauv][6: sab nrauv los yog derivation]-[7: cov yam ntxwv ua haujlwm]

Cov khoom 1-5 thiab 7 yog cim los ntawm cov tsiaj ntawv pinyin, thiab cov ntaub ntawv polymer raug suav los ntawm thawj tsab ntawv ntawm lub npe Askiv. Txhua yam tuaj yeem yog 1-2 tsab ntawv. Lub sijhawm thib rau yog 1-3 Tus lej.

Feem ntau siv code

Lub hom phiaj code - tsis cim raws li fais fab cable, K- (tswj cable), P- (lub teeb liab cable);

Tus neeg xyuas pib cov khoom siv code - tsis sau npe tooj liab (lossis CU), L- (aluminium);

Inner sheath code -Q- (polyvinyl chloride sheath), L- (aluminium package), H- (lub tes tsho roj hmab), V- (polyvinyl chloride sheath), lub plhaub sab hauv feem ntau tsis cim;

Txheej txheej txheej txheej -V- (polyvinyl chloride), Y- (polyethylene fais fab cable);

Tau txais code -D- (tsis muaj drip), P- (qhuav rwb thaiv tsev);

Tshem tawm txoj cai

Lub hauv paus ntsiab lus omission nyob rau hauv tus qauv: tooj liab yog lub ntsiab conductor khoom siv nyob rau hauv hlau thiab cable cov khoom, yog li lub code lub npe ntawm tooj liab tub ntxhais yog T xeev, tsuas yog liab qab hlau thiab liab qab conductor khoom. Cov xov hlau liab qab thiab cov khoom lag luam liab qab, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob electromagnetic tsis txhais tau hais tias hom kev lis kev cai, cov khoom siv hluav taws xob nrog cov xaim thiab cable thiab kev sib txuas lus cable tsis tau teev tseg, tab sis cov chav kawm me me lossis cov lej cim, thiab lwm yam.

Yam 7 yog siv ntau lub sijhawm tshwj xeeb lossis kev siv tshwj xeeb ntxiv ntawm cov cim, tom qab "-" hauv cov ntawv pinyin cim. Qee lub sij hawm txhawm rau tsom ib yam khoom, sau ua ntej. Xws li ZR- (nplaim hluav taws xob), NH- (hluav taws kub retardant), WDZ- (tsis muaj pa taws halogen dawb, cov qauv kev lag luam), TH- (siv hauv qhov kub thiab av noo), FY- (termite resistant, enterprise standard), thiab lwm yam.
