Hlau thiab cable hauv kev nkag siab dav kuj raug hu ua cable.Hauv kev nkag siab nqaim, cable hais txog cov kab hluav taws xob insulated.Nws tuaj yeem txhais tau tias yog ib qho kev sib sau ntawm ib lossis ntau qhov insulated hlau cores, ua ke nrog lawv cov kev ua tau zoo, tag nrho cov txheej tiv thaiv thiab txheej txheej.Lub cable kuj tseem yuav muaj cov khoom siv hluav taws xob ntxiv.
Tuam Tshoj cov khoom siv hlau thiab cable tau muab faib ua tsib pawg raws li lawv siv:
1. hlau liab.
2. winding hlau.
4. Kev sib txuas lus cables thiab kev sib txuas lus fiber ntau optic cables.
5. Cov khoom siv hluav taws xob nrog cov xaim thiab cable.
Lub hauv paus qauv ntawm hlau thiab cable.
1. Tus neeg xyuas pib: cov khoom uas ua rau tam sim no, xaim thiab cable specifications qhia nyob rau hauv cov nqe lus ntawm tus ntoo khaub lig-section ntawm tus neeg xyuas pib.
2. Rwb thaiv tsev: cov khoom siv rwb thaiv tsev sab nraud raws li nws cov degree ntawm kev tiv thaiv hluav taws xob.
Ua haujlwm tam sim no thiab suav.
Hluav taws xob (cable) cable ua hauj lwm tam sim no xam cov mis.
Ib-theem
I = P÷(U × cosΦ)
P - hwj chim (W);U - voltage (220V);cosΦ - fais fab tuag (0.8);I - theem kab tam sim no (A).
Peb theem
I = P÷(U × 1.732 × cosΦ)
P - hwj chim (W);U - voltage (380V);cosΦ - fais fab tuag (0.8);I - theem kab tam sim no (A).
Feem ntau, kev nyab xeeb txiav tawm ntawm tooj liab hlau yog 5-8A / mm2, thiab cov hlau txhuas yog 3-5A / mm2.
Nyob rau hauv ib-theem 220V kab, tam sim no ib 1KW hwj chim yog hais txog 4-5A, thiab nyob rau hauv peb-theem Circuit Court nrog sib npaug peb-theem load, tam sim no ib 1KW zog yog hais txog 2A.
Uas yog hais tias, nyob rau hauv ib tug ib-theem Circuit Court, txhua 1 square millimeter ntawm tooj liab conductor tuaj yeem tiv taus 1KW lub zog load;peb-theem sib npaug Circuit Court tuaj yeem tiv taus 2-2.5KW ntawm lub zog.
Tab sis qhov siab dua qhov kev khiav hauj lwm tam sim no ntawm cable, qhov me dua qhov kev nyab xeeb tam sim no ib square millimeter tuaj yeem tiv taus.
