Kev nkag siab txog cov kab hluav taws xob thiab cov xov hlau, lawv hom, kev siv, thiab kev teeb tsa yog qhov tseem ceeb rau kev ua haujlwm hluav taws xob zoo thiab nyab xeeb. Kab lus no muab kev nkag siab zoo rau cov ntsiab lus no.
Cables thiab xov hlau tuaj nyob rau hauv ntau hom thiab yog siv rau ntau lub hom phiaj. Cov cim thiab cov ntawv luv luv hauv kev txheeb xyuas cable pab kom paub txog thiab xaiv txoj cai cable rau cov ntawv thov tshwj xeeb.
Cov Cim Tseem Ceeb thiab Lawv Lub Ntsiab Lus:
B: Hluav taws xob xaim (qee zaum tsis qhia)
T: Copper core (default sawv cev)
L: Aluminium tub ntxhais
R: Mos tooj liab
V: Polyvinyl chloride rwb thaiv tsev
X: Roj hmab rwb thaiv tsev
F: Neoprene roj hmab
P: Tiv thaiv
B: Parallel
Piv txwv ntawm Common Wires:
BX, BLX: Rubber insulated xov hlau, siv rau kev txhim kho hauv tsev.
BXF, BLXF: Neoprene roj hmab insulated xov hlau, haum rau siv sab nraum zoov.
BXR: Rubber insulated cov xov hlau mos, siv hauv kev teeb tsa yuav tsum tau hloov pauv.
BV, BLV: Polyvinyl chloride insulated xov hlau, zoo dua rau qhov chaw ntub dej thiab huab cua-tshuaj.
RV: Ib leeg-ntxhais tooj liab tub ntxhais polyvinyl chloride insulated saj zawg zog xaim, siv rau kev sib txuas ntau yam khoom siv hauv xov tooj, cov cuab yeej, thiab cov khoom siv sib txuas lus.
Specification Indication Methods:
Piv txwv li: RVVP 2 × 32 / 0.2 txhais tau tias cov hlau mos nrog ob lub plhaub thiab thaiv, 2 cores nrog 32 strands ntawm 0.2mm txoj kab uas hla tooj liab txhua.
General Wire Specifications:
Kev ntsuas hluav taws xob: 300 / 500V, 450 / 750V
Hlau Loj: 1.5, 2.5, 4, 6, 10, 16, 25, 32, 50, 70, 95, 120, 150, 185, 240, 300, 400.
Kev tso cables suav nrog ntau txoj hauv kev, txhua qhov tsim nyog rau qhov chaw sib txawv thiab cov kev xav tau. Kev tso dej kom zoo ua kom muaj kev nyab xeeb, ua haujlwm tau zoo, thiab lub neej ntev ntawm cov cables.
Qhib Laying:
Nqe lus piav qhia: Cables tau muab tso rau ntawm phab ntsa, qab nthab, lossis ncej, pom thiab siv tau rau kev saib xyuas.
Daim ntaub ntawv: Siv nyob rau hauv cov tsev lag luam thiab kev lag luam uas qhov kev zoo nkauj tsis tshua muaj txiaj ntsig.
Qhov zoo: Yooj yim rau nruab thiab tswj.
Concealed Txheej:
Nqe lus piav qhia: Cov kab hluav taws xob tau muab zais rau hauv phab ntsa, hauv pem teb, lossis qab nthab.
Daim Ntawv Thov: Cov tsev nyob thiab cov chaw ua haujlwm uas muaj kev zoo nkauj tseem ceeb.
Qhov zoo: Tiv thaiv cables los ntawm kev puas tsuaj thiab txhim kho kev zoo nkauj.
Underground Txheej:
Nqe lus piav qhia: Cables tau faus rau hauv av hauv trench.
Daim ntaub ntawv: Sab nraum zoov thiab ntev-ntev cable khiav, xws li nruab nrab ntawm lub tsev lossis hla teb.
Qhov zoo: Tiv thaiv cables los ntawm huab cua thiab lub cev puas tsuaj.
Kev them nyiaj yug cable thiab kho txoj kev:
Clamp Boards: Siv los kho cov cables ntawm phab ntsa thiab qab nthab.
Porcelain Fwj: Muab rwb thaiv tsev thiab kev txhawb nqa rau cov khoom siv hluav taws xob.
Cov kav hlau: Cov kab txuas txuas rau kev teeb tsa thiab tiv thaiv cables.
Txoj Kev Laying Ntxiv:
Clipboard Wiring: Siv cov porcelain lossis yas clipboards los tuav thiab kho cov xov hlau.
Porcelain Bottle Wiring: Siv lub raj mis plooj (porcelain fwj) los txhawb thiab kho cov xov hlau, haum rau thaj tsam loj thiab qhov chaw ntub dej.
